74LVC16373APVG8 Equivalent & Substitute Parts

Part Overview

The 74LVC16373APVG8 is a D-Type Transparent Latch IC with 16-bit capacity, organized as 2 independent 8:8 channels with tri-state output capability. Manufactured by Renesas Electronics Corporation, this component operates across a 1.65V to 3.6V supply voltage range and is packaged in a 48-BSSOP form factor. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC16373APVG8 is determined by the following critical parameters:

Primary Compatibility Criteria:

Logic Type: D-Type Transparent Latch
Circuit Configuration: 2 Channel 8:8 (2 independent circuits)
Output Type: Tri-State
Voltage Supply Range: Minimum 1.65V support required
Operating Temperature Range: Minimum -40°C to 85°C coverage

Secondary Considerations:

Propagation Delay: 2.1ns baseline (faster alternatives acceptable)
Output Current Capability: 24mA minimum per output
Package compatibility: Surface mount packages with equivalent pinout

Substitute parts must maintain the 2-channel, 8:8 circuit architecture and tri-state output configuration. Parts with single-channel configurations or different circuit arrangements are not direct substitutes despite sharing the same base product number.

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

SN74LVC16373ADL, SN74LVC16373ADGGR, SN74LVC16373ADGVR, and SN74LVC16373DGGR from Texas Instruments provide the closest functional equivalence. These parts maintain identical electrical specifications (1.65V ~ 3.6V supply, 2.1ns propagation delay, 24mA output current, -40°C ~ 85°C operating range) and 2-channel 8:8 configuration. SN74LVC16373ADL matches the original 48-BSSOP package. SN74LVC16373ADGGR and SN74LVC16373DGGR use 48-TFSOP packaging. SN74LVC16373ADGVR employs 48-TVSOP packaging. All are ROHS3 compliant with MSL 1 rating.

Alternative Substitutes (Functional Equivalence with Considerations):

74LVC162373ADGG,11 and 74LVC16373ADGG,118 from NXP Semiconductors maintain the 2-channel 8:8 configuration and active product status. Complete electrical parameter specifications are not provided in available documentation; verification against design requirements is necessary before selection.

74LVC16373ADGGRG4 from Texas Instruments is discontinued at DiGi Electronics but maintains full electrical compatibility with the original part (1.65V ~ 3.6V, 2.1ns delay, 24mA output, -40°C ~ 85°C range) in 48-TFSOP packaging.

Not Recommended as Direct Substitutes:

CLVC16373AMDLREP features a single-channel 8:8 configuration, differing fundamentally from the 2-channel architecture of the original part. This configuration change makes it unsuitable for direct substitution despite active status and superior temperature range (-55°C ~ 125°C).

74LCX162373MTDX and 74LCX16373MTDX from Fairchild Semiconductor operate at 2V minimum supply voltage, exceeding the original part's 1.65V lower limit. The 74LCX162373MTDX offers faster propagation (1.5ns) but reduced output current (12mA). The 74LCX16373MTDX provides matching output current (24mA) but slower propagation (5.4ns). Both use 48-TFSOP packaging.

Frequently Asked Questions (FAQ)

Q: Can I use CLVC16373AMDLREP as a substitute for 74LVC16373APVG8?

A: No. CLVC16373AMDLREP is a single-channel device, while 74LVC16373APVG8 is a 2-channel part. The circuit architecture differs fundamentally, making this unsuitable for direct substitution despite sharing the same base product number.

Q: What is the difference between 48-BSSOP and 48-TFSOP packages?

A: Both are 48-pin surface mount packages with different physical dimensions. 48-BSSOP measures 0.295" (7.50mm) in width, while 48-TFSOP measures 0.240" (6.10mm) in width. Pinout compatibility must be verified before switching between these packages, as they may not be interchangeable on all PCB layouts.

Q: Are the Fairchild 74LCX parts compatible with my design using 1.65V supply voltage?

A: No. Fairchild 74LCX162373MTDX and 74LCX16373MTDX specify a minimum supply voltage of 2V, which exceeds the 1.65V lower limit of the original 74LVC16373APVG8. These parts are not suitable for designs operating at 1.65V.

Q: Why do some substitute parts have incomplete electrical specifications?

A: NXP Semiconductors parts 74LVC162373ADGG,11 and 74LVC16373ADGG,118 have limited parameter data in available documentation. Contact the manufacturer or authorized distributors for complete electrical specifications before design implementation.

Q: Which substitute offers the best performance improvement?

A: 74LCX162373MTDX from Fairchild Semiconductor provides the fastest propagation delay at 1.5ns compared to the original 2.1ns. However, this part operates at a minimum 2V supply voltage and provides reduced output current (12mA vs. 24mA), requiring verification against your specific design constraints.

Q: Can I use SN74LVC16373ADGVR in place of SN74LVC16373ADGGR?

A: Yes. Both parts are electrically identical with matching specifications (1.65V ~ 3.6V, 2.1ns delay, 24mA output, -40°C ~ 85°C range, 2-channel 8:8 configuration). The difference is packaging: SN74LVC16373ADGVR uses 48-TVSOP (0.173", 4.40mm width) while SN74LVC16373ADGGR uses 48-TFSOP (0.240", 6.10mm width). PCB layout compatibility must be confirmed.

Q: What does MSL 1 rating mean compared to MSL 3?

A: MSL (Moisture Sensitivity Level) indicates moisture absorption limits during storage. MSL 1 allows unlimited shelf life without baking, while MSL 3 requires baking after 168 hours of exposure to ambient humidity. Most active substitute parts carry MSL 1, providing better storage flexibility than the original MSL 3 part.
