SN74S373DWR

Overview

The SN74S373DWR is an octal transparent D-type latch manufactured by Texas Instruments, housed in a 20-pin Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of 4.75V to 5.25V and supports a standard operating temperature range of 0°C to 70°C. The device features eight independent D-type latches with tri-state outputs, providing high-speed data storage capabilities characteristic of the 74S logic series.

Feature Summary

• Octal configuration containing eight independent transparent D-type latches for parallel data storage
• Tri-state output capability allowing direct connection to bus systems without additional interface hardware
• Surface-mount SOIC-20 packaging designed for automated assembly processes

Applications

• Parallel data buffering in digital communication interfaces
• Register stages within microprocessor-based control systems
• Bus driver applications requiring temporary data retention

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and specific package variant against current datasheets. Check for obsolescence notices as this belongs to the legacy 74S logic family. Ensure proper handling procedures are followed during surface-mount installation.

Selection Notes

Select this component when high-speed latch performance is required alongside tri-state bus compatibility. Consider the 74S series characteristics regarding power consumption and propagation delay relative to system requirements. Evaluate thermal management needs given the operational temperature limits and package type constraints.
