CLVC16244AIDGGREP Equivalent & Substitute Parts

Part Overview

The CLVC16244AIDGGREP is a Buffer, Non-Inverting logic IC manufactured by Texas Instruments, part of the 74LVC series. This 48-TSSOP surface mount device provides 4 elements with 4 bits per element and 3-state output capability, operating across a supply voltage range of 1.65V to 3.6V. The device is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design requirements call for automotive-grade qualification or extended temperature operating ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the CLVC16244AIDGGREP is determined by the following critical parameters:

Logic Type: Buffer, Non-Inverting (4 Element, 4 Bit per Element)
Output Type: 3-State
Current Output Capability: 24mA minimum for both high and low states
Supply Voltage Range: Minimum 1.65V support required
Package: 48-TFSOP form factor
Operating Temperature: -40°C to 85°C minimum range
Surface Mount configuration

Substitute parts are grouped into three categories based on their relationship to the main part:

Parametric Equivalents maintain identical electrical specifications and packaging while differing in qualification level or packaging format (Cut Tape vs. Tape & Reel).

Direct Manufacturer Equivalents are from alternative manufacturers but meet all core electrical and mechanical parameters, with minor variations in supply voltage floor or output current specifications.

MFR Recommended Alternatives provide functional equivalence with acceptable parameter variations, including different series designations, modified output current ratings, or extended temperature ranges, suitable for applications where these variations do not impact system performance.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

CLVC16244AIDGGRQ1 and SN74ALVC16244ADGGR are direct parametric equivalents from Texas Instruments with identical electrical specifications. CLVC16244AIDGGRQ1 includes automotive-grade qualification (AEC-Q100) and is suitable for applications requiring automotive compliance. Both maintain the full 24mA output current and 1.65V minimum supply voltage of the original part.

Secondary Substitutes (Acceptable with Design Review)

SN74ALVCH16244DGGR, M74LCX16244DTR2G, and 74LCX16244MTD provide functional equivalence with a minimum supply voltage floor of 2V instead of 1.65V. These parts are suitable for applications where the system supply voltage does not drop below 2V. M74LCX16244DTR2G is from onsemi and maintains 24mA output current. 74LCX16244MTD is available in high inventory quantity (14490 units) but carries Last Time Buy status.

Alternative Substitutes (Parameter Variations)

74LCX162244MTDX and 74LVC162244APAG reduce output current to 12mA, suitable only for applications with lower current drive requirements. 74LVC162244ADGG:11 from Nexperia extends the operating temperature range to -40°C to 125°C and supports supply voltage down to 1.2V, making it suitable for extended temperature applications. 74LVC162244APVG uses a 48-BSSOP package (0.295" width) instead of 48-TFSOP, requiring PCB layout modification.

Product Status Considerations

Parts marked as Active (CLVC16244AIDGGREP, CLVC16244AIDGGRQ1, SN74ALVC16244ADGGR, SN74ALVCH16244DGGR, M74LCX16244DTR2G, 74LCX162244MTDX, 74LVC162244ADGG:11, 74LVC162244APAG, 74LVC162244APVG) are in current production. Parts marked as Last Time Buy (74LCX16244MTD, 74LCXH16244MTDX) have limited availability and should be used only when inventory is confirmed.

Frequently Asked Questions (FAQ)

Q: Can I substitute CLVC16244AIDGGREP with a part that has 12mA output current instead of 24mA?

A: Substitution with 12mA output current parts (74LCX162244MTDX, 74LVC162244APAG, 74LVC162244APVG) is possible only if your circuit design does not require the full 24mA drive capability. Review your load impedance and signal integrity requirements before selecting a lower-current alternative.

Q: What is the difference between CLVC16244AIDGGREP and CLVC16244AIDGGRQ1?

A: Both parts are electrically identical with the same 24mA output current, 1.65V to 3.6V supply range, and -40°C to 85°C operating temperature. CLVC16244AIDGGRQ1 includes automotive-grade qualification (AEC-Q100) and is packaged in Tape & Reel format, while CLVC16244AIDGGREP is packaged in Cut Tape format. Select CLVC16244AIDGGRQ1 for automotive applications.

Q: Can I use 74LVC162244APVG as a direct replacement?

A: 74LVC162244APVG is functionally equivalent but uses a 48-BSSOP package (0.295" width) instead of the 48-TFSOP package (0.240" width) of the original part. This requires PCB layout modification and is not a direct pin-compatible replacement without board redesign.

Q: Why do some substitutes have a minimum supply voltage of 2V instead of 1.65V?

A: Different logic families have different minimum operating voltage specifications. Parts from the 74LCX series (M74LCX16244DTR2G, 74LCX16244MTD, 74LCXH16244MTDX) specify 2V minimum, while 74LVC series parts specify 1.65V minimum. Select 74LVC series substitutes if your application requires operation below 2V supply voltage.

Q: What does Last Time Buy status mean?

A: Last Time Buy indicates the manufacturer has announced end-of-life for that part number. 74LCX16244MTD and 74LCXH16244MTDX are in Last Time Buy status, meaning current inventory is available but no future production is planned. Use these parts only when confirmed inventory meets your long-term requirements.

Q: Is 74LVC162244ADGG:11 suitable for high-temperature applications?

A: Yes. 74LVC162244ADGG:11 operates across -40°C to 125°C, extending the upper temperature limit by 40°C compared to the original part's -40°C to 85°C range. This part is suitable for applications requiring extended temperature operation. Note that output current is reduced to 12mA.

Q: Can I mix different substitute parts in the same design?

A: All listed substitutes maintain the same logic function (Buffer, Non-Inverting, 4 Element, 4 Bit per Element, 3-State Output) and 48-TFSOP package form factor (except 74LVC162244APVG). Mixing parts with different output current ratings (24mA vs. 12mA) or supply voltage ranges requires circuit analysis to confirm compatibility with your specific load and power supply specifications.
