SN74AHC373DWR

Overview

The SN74AHC373DWR is an octal transparent D-type flip-flop manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2V to 5.5V and utilizes a 20-SOIC surface-mount package. The device exhibits propagation delays of 14.9ns and 9.2ns with a static current consumption of 4µA. Output drive capabilities include 32mA at low level and -8mA at high level. It supports industrial temperature ranges and complies with RoHS standards.

Feature Summary

• Octal transparent latch architecture providing eight independent data storage channels
• Three-state output configuration enabling direct bus driving applications
• Wide operating voltage compatibility supporting both 2V and 5.5V logic systems

Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in microprocessor interfaces
• Buffering for address and data buses

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required environmental certifications such as RoHS compliance before integration into final assemblies. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations.

Selection Notes

Select this component when designing systems requiring wide voltage flexibility between 2V and 5.5V. The low static current makes it suitable for power-sensitive applications compared to older logic families. Verify that the SOIC-20 package dimensions align with the target PCB footprint and thermal management requirements.

Part Context

This part belongs to the Texas Instruments 74AHC logic family, which offers performance comparable to 74ALSTTL while maintaining CMOS low-power advantages. The SN74AHC373 serves as an octal latch variant within this series, distinct from flip-flops like the SN74AHC374. It replaces legacy HC series parts where faster switching speeds are necessary.

Replacement Considerations

The SN74AHC373DWRE4 is a verified equivalent part number from Texas Instruments offering identical functionality and specifications.
