74LVCH162373ADGG:1

Latches Overview

The Nexperia 74LVCH162373ADGG:1 is a 16-bit D-type transparent latch featuring 30 Ω series termination resistors and 5 V tolerant inputs/outputs with 3-state control. It operates on a supply voltage range of 1.2 V to 3.6 V, supporting mixed 3.3 V and 5 V environments. The device includes bus hold circuitry for all data inputs and IOFF circuitry for partial power-down applications. Packaged in a TSSOP48 (SOT362-1) format, it provides two independent 8-bit latch sections with separate enables.

Latches Feature Summary

• Integrated 30 Ohm series termination resistors for signal integrity
• Bus hold functionality on all data inputs to maintain state
• IOFF circuitry prevents backflow current during partial power-down
• 5 V tolerant I/Os compatible with mixed voltage systems

Latches Applications

• Data buffering in high-speed digital interfaces
• Address/data latching in memory architectures
• Signal translation between 3.3 V and 5 V logic domains
• Parallel data storage in embedded processing systems

Latches Procurement Notes

Verify the specific ordering suffix :1 against the manufacturer's latest documentation to confirm tape-and-reel specifications and packaging details. Ensure compatibility with the target PCB footprint SOT362-1. Confirm that the LVCH variant with bus hold meets the design requirements, as the standard LVC version lacks this feature. Cross-reference the RoHS and REACH compliance status with current regulatory standards before finalizing procurement.

Latches Selection Notes

Select the 74LVCH162373ADGG:1 when bus hold capability is required to prevent floating inputs, distinguishing it from the non-bus-hold 74LVC162373A variant. The LVCH series offers improved noise immunity compared to standard LVC devices. Ensure the application utilizes the 3-state outputs correctly via the nOE pins. Verify that the 30 Ω internal termination resistors align with the transmission line impedance requirements of the system.

Latches Part Context

This component belongs to the Nexperia 74LVCH162373A family of 16-bit transparent latches. It shares the same pinout and core functionality as the 74LVC162373A but includes enhanced bus hold features and optimized performance characteristics typical of the LVCH series. The ADGG designation indicates the TSSOP48 package type suitable for surface-mount assembly.

Latches Replacement Considerations

The 74LVC162373ADGG is a functional alternative but lacks the bus hold feature found in the LVCH variant. Direct replacements must be verified against the specific bus hold requirement. Other 16-bit latches from different manufacturers may require significant schematic and layout modifications due to pinout or electrical differences.
