CD74FCT821AEN

Overview

The CD74FCT821AEN is a BiCMOS FCT interface logic device featuring ten non-inverting D-type flip-flops with three-state outputs. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 100 MHz. The component utilizes a 24-pin PDIP package and functions across an industrial temperature range of 0°C to +70°C.

Feature Summary

Integrates ten non-inverting D-type flip-flops for high-density data storage applications
Provides three-state outputs to facilitate direct bus interfacing without external buffers
Utilizes BiCMOS technology to achieve high-speed performance compatible with Fast CMOS (FCT) standards

Applications

High-speed parallel data buffering in computer systems
Interface logic between microprocessors and peripheral devices
Clock distribution networks requiring precise timing control

Procurement Notes

Verify the specific suffix 'AEN' corresponds to the 24-pin PDIP package and commercial temperature grade. Confirm RoHS compliance status through official manufacturer documentation or current datasheets, as environmental certifications may vary by production batch. Ensure the supplier provides valid traceability for this Texas Instruments part number.

Selection Notes

Select this component when ten synchronized data latches with tri-state capability are required. It is suitable for designs needing 5V operation with FCT-compatible input and output levels. Consider the PDIP package constraints for prototyping or through-hole assembly requirements compared to surface-mount alternatives.

Part Context

This device belongs to the Texas Instruments CD74FCT series, which focuses on high-speed BiCMOS logic solutions. The FCT family bridges the performance gap between standard CMOS and ECL technologies, offering faster switching speeds while maintaining CMOS power efficiency and noise immunity characteristics.
