CD74ACT323E

Shift Registers Overview

The CD74ACT323E is an octal transparent latch with 3-state outputs manufactured by Harris Corporation. It belongs to the ACT logic family, utilizing advanced CMOS technology for high-speed operation. The device features eight D-type latches with tri-state output control, allowing for efficient data bus interfacing. It operates within a supply voltage range of 2V to 6V and supports through-hole mounting in a standard 20-pin DIP package.

Shift Registers Feature Summary

• Octal configuration providing eight independent transparent latches
• Tri-state outputs enabling direct bus-driven applications
• Advanced CMOS construction for high-speed performance
• Transparent latch architecture for immediate data capture

Shift Registers Applications

• Parallel-to-serial data conversion systems
• Bus-oriented memory register structures
• High-speed data buffering interfaces
• Digital signal processing storage elements

Shift Registers Procurement Notes

Verify component authenticity as this part is obsolete. Confirm manufacturer origin between Harris Semiconductor and Texas Instruments due to acquisition history. Check datasheet revision levels for pinout consistency. Ensure packaging matches specified 20-PDIP requirements. Validate RoHS compliance status against specific manufacturing date codes.

Shift Registers Selection Notes

Select this component when requiring octal latching with bus isolation capabilities. The ACT series offers superior speed compared to standard HC or HCT variants. Consider the 20-PDIP package for prototyping or legacy board replacements. Verify voltage compatibility with the 2V to 6V operating range before integration into the target circuit design.

Shift Registers Part Context

This component is part of the 74ACT series of high-speed CMOS logic devices originally developed by Harris Semiconductor. Following the acquisition of Harris Semiconductor by Texas Instruments, documentation and production rights were transferred. The CD74ACT323E represents a specialized latch variant within this broader logic family ecosystem.

Shift Registers Replacement Considerations

CD74ACT573 serves as a functional equivalent with identical pinout and electrical characteristics. CD74ACT574 provides similar latching functionality but utilizes edge-triggered rather than transparent operation. Verify package compatibility and voltage specifications when substituting these alternative components.
