CD74ACT373E

Latches Overview

The CD74ACT373E is an octal transparent latch manufactured by Harris Corporation, belonging to the 74ACT logic series. It features eight D-type latches with three-state outputs in a 20-pin PDIP package. Key electrical parameters include a propagation delay of 10.4 ns at 5 V, static current of 8 uA, low-level output current of 32 mA, and high-level output current of -24 mA. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a temperature range from -55 C to +125 C.

Latches Feature Summary

• Octal transparent latch configuration with common latch enable control
• Three-state outputs providing bus line driving capacity
• Buffered inputs for signal integrity

Latches Applications

• Bus-oriented memory mapping
• Registering I/O devices
• Working as a latch

Latches Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired Harris Corporation's logic business. Ensure the specific part number matches the required ACT series specifications rather than HC or HCT variants. Confirm RoHS compliance status through official documentation, as legacy Harris parts may have different environmental certifications compared to modern TI equivalents.

Latches Selection Notes

Select this component when high-speed CMOS performance is required with LSTTL compatibility. The ACT series offers faster switching speeds than standard HC or HCT logic families while maintaining low power consumption. Verify that the 4.5 V to 5.5 V operating voltage aligns with the system design requirements before integration.

Latches Part Context

This component is part of the broader 74ACT family of high-speed CMOS logic devices. It serves as a digital storage element capable of holding eight bits of data. The device is functionally similar to other octal latches but distinguished by its specific ACT series speed and drive characteristics provided by Harris Corporation prior to industry consolidations.
