SN74F373DWRG4

Overview

The SN74F373DWRG4 is an octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It belongs to the 74F logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 8.6 ns, with low-level output current capability of 24 mA and high-level output current of 3 mA. It is housed in a 20-SOIC package and supports surface-mount installation.

Feature Summary

• Octal transparent D-type latch architecture providing eight independent data storage channels
• Three-state outputs enabling direct bus-driven connections without external buffers
• High-speed switching performance characteristic of the 74F logic family

Applications

• Registering data on digital buses
• Driving bus lines in computer systems
• Temporary data storage in memory architectures

Procurement Notes

Verify the G4 suffix indicates lead-free and RoHS compliance per manufacturer standards. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Check for obsolescence status as F-series components may have limited availability compared to newer logic families. Ensure voltage levels align with your 4.5V to 5.5V system design constraints.

Selection Notes

Select this component when high-speed latching is required alongside bus driving capabilities. The 74F series offers faster propagation than HC or HCT variants but consumes more power. Consider thermal management due to higher current drive capabilities. Verify compatibility with existing 5V logic interfaces before integration into the circuit design.

Part Context

This part is part of the SN74F373 family of octal latches. The 'DWR' designation specifies the tape-and-reel packaging format in a 20-pin small-outline integrated circuit. The 'G4' suffix typically denotes environmental compliance including lead-free construction. It serves as a standard solution for parallel data retention in high-speed digital applications.

Replacement Considerations

SN74F373DWR is the non-compliant equivalent. SN74F373DBR offers identical electrical characteristics in reel packaging. SN74F373N provides through-hole alternative. SN74F373NSR offers SOIC-20 reel variant.
