SN74HC373NE4

Overview

The SN74HC373NE4 is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features high-current true outputs capable of driving up to 15 LSTTL loads. The device includes eight latches in a single package, utilizing a PDIP-20 through-hole package. Typical propagation delay is 13ns at 5V, with maximum operating temperatures reaching +85°C.

Feature Summary

• Octal transparent D-type latches with 3-state outputs
• Wide operating voltage range from 2V to 6V
• High-current outputs for driving capacitive or low-impedance loads

Applications

• Buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Procurement Notes

Verify the component matches the exact SN74HC373NE4 designation to ensure correct packaging and lead finish specifications. Confirm RoHS compliance status and check for any specific environmental certifications required for your application. Ensure the supplier provides valid traceability documentation consistent with Texas Instruments manufacturing standards.

Selection Notes

Select this component when designing systems requiring parallel data storage with tri-state control capabilities. It is suitable for applications needing wide voltage flexibility between 2V and 6V. Consider the PDIP-20 package constraints for through-hole assembly processes and verify thermal management requirements against the specified junction-to-ambient resistance values.

Part Context

This part belongs to the SNx4HC373 family of octal transparent D-type latches. It shares functional characteristics with other variants in the series but differs in physical packaging and specific ordering suffixes. The 'N' suffix indicates the PDIP-20 package, while 'E4' denotes lead-free composition compliant with specific environmental directives.
