SN74ACT373NSR

Overview

The SN74ACT373NSR is an octal D-type transparent latch manufactured by Texas Instruments, belonging to the SN74ACT logic series. It features eight non-inverting D-type latches with a common level-enable input, packaged in a 20-pin SOIC (N) surface-mount device. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 10 ns. It draws a maximum static current of 4 uA and provides output drive capabilities of 32 mA at low levels and -24 mA at high levels. The device is rated for operation between -40°C and +85°C.

Feature Summary

• Contains eight independent D-type transparent latches sharing a single level-enable control input.
• Utilizes Texas Instruments ACT logic technology to achieve fast switching speeds while maintaining low power consumption.
• Provides robust output drive strength suitable for driving bus lines and moderate capacitive loads.

Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in digital systems
• Bus interface buffering applications

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel sources genuine components from authorized distributors to guarantee compliance with RoHS standards and operational temperature ratings. Cross-reference the manufacturer part number with the latest datasheet revision history to validate electrical characteristics before integration.

Selection Notes

Select this component when designing 5V logic systems requiring high-speed data latching with low quiescent current. The ACT series offers superior speed-power product compared to standard TTL or HC families. Consider the SOIC-20 package dimensions for PCB layout constraints and verify that the required output current capability aligns with the load impedance of the destination circuitry.

Part Context

This device is part of the broader SN74ACT family of high-speed CMOS logic devices produced by Texas Instruments. The ACT series bridges the performance gap between older TTL technologies and modern low-voltage CMOS solutions. Similar variants in the family may include tri-state outputs or different packaging options, but the base SN74ACT373 design specifically focuses on transparent latching functionality without output state control.
