SN74ACT373DWR

Overview

The SN74ACT373DWR is an octal D-type transparent latch manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes ACT logic technology, providing low static power consumption with a maximum quiescent current of 4 µA. It is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package designed for surface-mount applications. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type transparent latch architecture
• Three-state output capability
• Low static power consumption via ACT technology

Applications

• Registering data in digital systems
• Buffering bus signals
• Data storage in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-20 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the design accommodates the specified 4.5V to 5.5V supply voltage constraints.

Selection Notes

Select this component when an octal latch with three-state outputs is required for 5V logic systems. The ACT series offers faster switching speeds compared to standard LS or HC families while maintaining CMOS input compatibility. Consider the SOIC-20 package dimensions for PCB layout constraints.

Part Context

This part belongs to the Texas Instruments 74ACT logic family, which combines the speed of bipolar circuits with the low power consumption of CMOS technology. It is functionally similar to other octal latches like the SN74ACT573 but distinguished by its specific pinout and internal transparency characteristics defined in the official datasheet.

Replacement Considerations

Check for direct equivalents such as the SN74ACT573 if pin compatibility allows. Verify that any substitute maintains the same three-state output functionality and ACT logic speed characteristics.
