SN74HCT373ANSR

Latches Overview

The SN74HCT373ANSR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the HCT logic series. It features eight D-type latches with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 16 ns at 5 V. It provides a low-level output current of 32 mA and a high-level output current of -2.6 mA. The component functions across a temperature range of 0°C to +70°C with a static current of 25 mA.

Latches Feature Summary

• Octal transparent D-type latch architecture with tri-state outputs
• Compatible with standard CMOS logic levels via HCT series interface
• Surface-mount packaging for automated assembly integration

Latches Applications

• Parallel data storage in digital systems

Latches Procurement Notes

Verify the specific suffix 'ANSR' against official Texas Instruments documentation to confirm the exact package variant and tape-and-reel specifications. Ensure the operating temperature range aligns with system requirements, as industrial variants may differ. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for bus-driven applications. The HCT series ensures compatibility with TTL-driven systems while maintaining CMOS noise immunity. Verify that the 20-pin SOIC package fits the PCB layout constraints and that the 4.5 V to 5.5 V supply voltage matches the system power rails.

Latches Part Context

This part belongs to the SN74HCT373 family of octal D-type latches. It shares functional similarities with other 74HCT series devices but is distinct from HC or ALS variants due to its specific input thresholds and speed characteristics. The 'A' prefix typically denotes improved specifications or updated manufacturing revisions within the Texas Instruments portfolio.
