74AHCT373D,118

Latches Overview

The 74AHCT373D,118 is an octal D-type transparent latch with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device includes latch enable (LE) and output enable (OE) inputs for data storage and bus isolation. It is housed in a SO20 plastic small outline package (SOT163-1).

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-state outputs.
• Overvoltage tolerant inputs allowing operation in mixed voltage environments.
• CMOS low power dissipation with high noise immunity.
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Latches Applications

• Data storage in digital systems.
• Bus driver applications requiring latching capability.
• Mixed voltage translation interfaces.

Latches Procurement Notes

Verify the manufacturer designation as Nexperia on official documentation. Confirm the specific ordering suffix ',118' corresponds to the SO20 package variant SOT163-1. Ensure compliance with RoHS3 specifications and check for any recent Product Change Notifications (PCN) regarding assembly or labeling updates before finalizing procurement.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required. The AHCT series ensures compatibility with standard CMOS logic levels while offering HCT-compatible input thresholds. Verify that the operating temperature range of -40 °C to +125 °C meets the environmental requirements of the target application.

Latches Part Context

This part belongs to the 74AHC/AHCT logic family produced by Nexperia. It is functionally similar to the 74AHC373 but utilizes AHCT input structures for TTL/CMOS compatibility. The 'D' suffix indicates the SO20 package type, distinguishing it from TSSOP variants like the 74AHC373PW.

Latches Replacement Considerations

The 74AHC373PW,118 serves as a pin-compatible alternative using a TSSOP20 package. Other 74AHC373 variants from different manufacturers may require verification of input/output electrical characteristics and package dimensions to ensure interchangeability.
