Part Overview
The 74LVC162244APVG8 is a non-inverting buffer IC manufactured by Renesas Electronics Corporation, designed for low-voltage CMOS logic applications. This 48-pin SSOP device provides 4 elements with 4 bits per element and 3-state output capability, operating across a 2.7V to 3.6V supply voltage range. The part is currently active in production with 769 units in stock. Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging or thermal specifications are required, or when design flexibility demands components from different manufacturers with compatible electrical characteristics.

Substitute Part Grouping Explanation
Substitution of the 74LVC162244APVG8 is determined by the following critical parameters:
Functional Equivalence Requirements:
- Logic type must be Buffer, Non-Inverting
- Element count must be 4 with 4 bits per element
- Output configuration must be 3-State
- Supply voltage range must encompass or exceed 2.7V to 3.6V
- Operating temperature range must support -40°C to 85°C minimum
Electrical Compatibility:
- Output current capability (12mA minimum for High and Low states)
- Input/output voltage levels compatible with 3.3V logic systems
Physical and Manufacturing Considerations:
- Surface mount technology required
- 48-pin package format (SSOP, TSSOP, or TFSOP variants acceptable)
- RoHS3 compliance maintained
Substitute parts are grouped into two categories: direct functional equivalents with identical electrical specifications, and compatible alternatives with enhanced specifications (higher current drive, extended temperature range, or improved supply voltage tolerance) that maintain backward compatibility.

Engineering Selection Recommendations
Primary Substitutes (Active Status, Full Compatibility):
The 74LVC162244ADGG:11 (Nexperia) and 74LVCH162244ADGG,1 (Nexperia) are recommended as primary substitutes. Both maintain the 74LVC series designation, support the full 2.7V to 3.6V supply range of the original part, and are currently in active production. The Nexperia variants offer extended operating temperature range (-40°C to 125°C) and improved supply voltage tolerance (1.2V minimum), providing design margin for future applications. Both parts carry ROHS3 compliance and MSL 1 rating, indicating superior moisture handling compared to the original MSL 3 specification.
Secondary Substitutes (Enhanced Specifications):
The NXP Semiconductors variants (74LVC16244ADGG,112 and 74LVC16244ADGG,118) provide doubled output current capability (24mA versus 12mA) while maintaining the same 48-pin TSSOP package footprint. These parts are suitable for applications requiring higher drive capability and are actively produced with substantial inventory availability (6995 and 57260 units respectively). Both support the extended temperature range and lower minimum supply voltage (1.2V).
Alternative Substitutes (Compatibility with Limitations):
The 74LCX series parts (Fairchild 74LCX162244MTDX and onsemi 74LCX16244MTD) maintain electrical compatibility but carry "Last Time Buy" or discontinued status. The onsemi 74LCXH16244MTDX is similarly marked as Last Time Buy. These alternatives are suitable only for applications where long-term supply continuity is not critical.
The Texas Instruments CLVC16244AIDGGREP and CLVC16244AIDGGRQ1 variants provide 24mA output current and are actively produced. The Q1 variant includes AEC-Q100 automotive qualification, suitable for automotive-grade applications. Both support 1.65V to 3.6V supply range and maintain -40°C to 85°C operating temperature specification matching the original part.
Avoid:
The 74LVCH16244ADGGRG4 (Texas Instruments) is marked as discontinued at DiGi Electronics and should not be selected for new designs requiring long-term availability.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with higher output current (24mA) in place of the 12mA original specification?
A: Yes. Higher output current capability is a superset of the original specification and provides design margin. The 24mA variants (NXP 74LVC16244ADGG,112, onsemi 74LCX16244MTD, and Texas Instruments CLVC16244AIDGGREP) are direct functional substitutes with enhanced drive capability. No circuit modifications are required.
Q: Are the 48-TSSOP and 48-TFSOP packages pin-compatible with the original 48-BSSOP?
A: All three package variants (BSSOP, TSSOP, TFSOP) are 48-pin configurations with identical pinout and electrical characteristics. The primary difference is physical footprint width: BSSOP is 7.50mm, while TSSOP and TFSOP are 6.10mm. PCB layout modifications may be required if the original design uses the wider BSSOP footprint. Verify footprint compatibility with your PCB design before substitution.
Q: What is the difference between 74LVC and 74LVCH series parts?
A: Both series provide non-inverting buffer functionality with identical pin configurations and electrical performance. The 74LVCH designation indicates enhanced specifications, typically including higher output current capability. For the 74LVC162244 and 74LVCH162244 variants provided, both support the same supply voltage and temperature ranges. Selection between series is based on output current requirements and manufacturer availability.
Q: Can I substitute a part with 1.2V minimum supply voltage when my design operates at 2.7V?
A: Yes. A part rated for 1.2V to 3.6V supply range is fully compatible with a 2.7V to 3.6V design. The lower minimum voltage specification provides additional design margin and indicates improved low-voltage performance. No circuit modifications are necessary.
Q: Why do some substitutes show "Last Time Buy" status?
A: Last Time Buy status indicates the manufacturer has announced end-of-life for that part number. While current inventory may be available, future procurement will not be possible. These parts should be avoided for new designs or applications requiring long-term component availability. Select alternatives marked as "Active" status for production designs.
Q: Is the Nexperia 74LVC162244ADGG:11 a direct replacement for the Renesas 74LVC162244APVG8?
A: Yes. Both parts share the 74LVC series designation, identical pin configuration, and equivalent electrical specifications (12mA output current, 2.7V to 3.6V supply range). The Nexperia variant offers extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) and improved moisture sensitivity rating (MSL 1 versus MSL 3). No design changes are required for substitution.
Q: Which substitute offers the best long-term availability?
A: The NXP Semiconductors variants (74LVC16244ADGG,112 and 74LVC16244ADGG,118) demonstrate the highest inventory levels (6995 and 57260 units respectively) and are marked as Active status with no announced end-of-life. These parts are recommended for designs requiring extended production runs or long-term supply security.
