CY74FCT821BTPC

Overview

The CY74FCT821BTPC is a 10-bit bus interface register with tri-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and features non-inverting polarity. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. It is housed in a 24-pin PDIP package designed for through-hole installation. The component functions as a D-type flip-flop with positive edge triggering, providing reliable data storage and transfer capabilities for high-speed digital applications.

Feature Summary

• Provides 10-bit bus interface registration capability
• Features tri-state outputs for efficient bus sharing
• Supports positive edge-triggered D-type flip-flop operation

Applications

• High-speed data bus interfacing systems
• Digital signal processing equipment
• Computer peripheral interface circuits

Procurement Notes

Verify component authenticity and datasheet alignment before procurement. Confirm that the specific BTPC suffix corresponds to the required 24-PDIP through-hole package variant. Ensure compatibility with existing PCB footprints and soldering processes. Check for any obsolescence notices or lifecycle status updates from the manufacturer to guarantee long-term supply availability.

Selection Notes

Select this component when a 10-bit registered interface with tri-state control is required. It is suitable for designs needing positive edge-triggered data latching in a through-hole format. Consider the FCT series speed and drive strength characteristics. Verify that the 24-pin DIP package fits the mechanical constraints of the target assembly.

Part Context

This part is part of the CY74FCT821 family of bus interface registers. It shares functional similarities with other 10-bit variants but differs in packaging. The BTPC designation specifically indicates the 24-pin plastic dual in-line package configuration. It complements other FCT logic components for complete system integration.
