SN74F373DWR

Overview

The SN74F373DWR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74F logic series. It features eight D-type transparent latches with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a propagation delay of 8.6ns. Output drive capabilities include 3mA for high-level and 24mA for low-level currents. It functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Contains eight independent D-type transparent latches for parallel data storage
• Provides three-state outputs to facilitate bus-driven systems
• Utilizes fast Schottky (F) logic technology for high-speed performance
• Designed for surface-mount installation in compact electronic assemblies

Applications

• Registering data on digital buses
• Driving bus-oriented memory architectures
• Clock-controlled data storage circuits
• Parallel-to-serial conversion interfaces

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the 20-SOIC package and tape-and-reel packaging configuration. Confirm RoHS3 compliance status and ensure the manufacturer designation matches Texas Instruments specifications. Cross-reference the ordering information against official distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when high-speed data latching is required within standard 5V logic environments. The 74F series offers superior speed compared to LS or HC variants but consumes more power. Ensure the application design accommodates the specific output drive requirements and thermal characteristics associated with the F-series logic family constraints.

Part Context

This part belongs to the widely adopted 74xx logic family, specifically the F (Fast) sub-family known for rapid switching speeds. The SN74F373 serves as a fundamental building block for sequential logic designs, providing reliable data retention and transfer capabilities in complex integrated circuit systems requiring precise timing control.

Replacement Considerations

SN74F373N provides equivalent functionality in a through-hole PDIP-20 package. SN74F373NSR offers identical electrical performance in a smaller 20-SO package format. Verify pin compatibility and package dimensions when substituting these alternatives.
