74AHC373PW,112

Latches Overview

The Nexperia 74AHC373PW,112 is an octal D-type transparent latch with 3-state outputs housed in a TSSOP20 package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. Propagation delays (Dn to Qn) range from 1.0 ns to 19.0 ns depending on load capacitance and voltage. The device features Schmitt-trigger inputs, overvoltage tolerance up to 5.5 V, and ESD protection exceeding 2000 V (HBM).

Latches Feature Summary

• Octal D-type transparent latch architecture with common 3-state output enable.
• Overvoltage tolerant inputs allowing operation in mixed voltage environments.
• Schmitt-trigger action on all inputs for high noise immunity.
• Robust ESD protection meeting ANSI/ESDA/JEDEC JS-001 Class 2 and JS-002 Class C3 standards.

Latches Applications

• Bus-oriented applications requiring data storage and transfer.
• Mixed voltage translation between different logic families.
• Parallel data buffering and register stages in digital systems.

Latches Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and temperature grade. Confirm RoHS compliance status via official datasheets before integration. Check for any product discontinuation notices or lifecycle changes directly from the manufacturer to ensure long-term availability for production.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus applications. Ensure the system voltage falls within the 2.0 V to 5.5 V operating range. Verify that the TSSOP20 package dimensions fit the PCB layout constraints. Consider the propagation delay specifications relative to the system clock speed and load capacitance requirements.

Latches Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other industry-standard octal latches but offers specific performance characteristics defined by the AHC technology node. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package variant.

Latches Replacement Considerations

Direct pin-compatible substitutes include the 74AHCT373PW variants for TTL-level input compatibility. Other 74AHC373 packages such as SO20 (74AHC373D) are electrically equivalent but require different footprint considerations. Cross-reference with other manufacturers' 74AHC373 equivalents for form-fit-function verification.
