SN74S373DW

Overview

The SN74S373DW is an octal D-type transparent latch manufactured by Texas Instruments, belonging to the 74AS logic series. It features eight independent latches with tri-state outputs in a single package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 6 ns. It provides a low-level output current of 32 mA and a high-level output current of -15 mA. The component is housed in a 20-pin SOIC package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Offers eight independent D-type transparent latches in a single integrated circuit package
• Features tri-state bus-driving outputs for efficient data transfer on shared buses
• Includes buffered control inputs to manage parallel access loading effectively

Applications

• High-speed digital data storage systems requiring fast latch operations
• Bus-oriented memory architectures utilizing tri-state output capabilities
• Parallel-to-serial conversion circuits in communication interfaces

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing lot details prior to integration. Ensure proper handling procedures are followed during installation to maintain signal integrity and device longevity in operational environments.

Selection Notes

Select this component for applications demanding high-speed performance from the AS logic family. Compare against HC or LS variants if lower power consumption or wider voltage ranges are required instead of speed. Validate that the SOIC package format aligns with existing PCB footprint designs and thermal management requirements.

Part Context

This part belongs to the Texas Instruments 74AS series, known for advanced Schottky technology providing high speed. It serves as a specialized latch solution compared to standard TTL or CMOS alternatives. The DW suffix indicates a plastic small-outline package suitable for surface-mount assembly techniques.

Replacement Considerations

The SN74LS373DWR is a documented substitute offering similar functionality but with slower switching speeds. Verify compatibility regarding propagation delay and drive strength differences when transitioning between these logic families.
