CY74FCT823CTSOCT

Overview

The CY74FCT823CTSOCT is a 9-bit D-type flip-flop manufactured by Texas Instruments, belonging to the 74FCT logic series. It operates within a supply voltage range of 4.75 V to 5.25 V and utilizes CMOS technology. The device features tri-state, non-inverting outputs with drive capabilities of 32 mA high and 64 mA low. It is housed in a 24-SOIC package and supports surface mount installation. The component exhibits a maximum propagation delay of 20 ns at 5 V with 300 pF load and maintains a static current of 200 µA across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates nine D-type flip-flops with positive edge triggering for sequential data storage applications.
• Provides tri-state output control to manage bus line sharing and signal isolation effectively.
• Features master reset functionality to initialize all flip-flop states simultaneously.

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• Temporary data storage in microprocessor interfaces

Procurement Notes

Verify the specific suffix CT against official Texas Instruments documentation to confirm the tape and reel packaging configuration. Ensure the part number matches the exact SOIC-24 footprint requirements for your PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a 9-bit parallel storage solution with tri-state buffering is required within standard 5V logic families. Consider the 20 ns propagation delay and 300 pF capacitive load limits for timing-critical designs. Evaluate the 24-SOIC package dimensions against available board space constraints during the initial schematic capture phase.

Part Context

This device belongs to the Texas Instruments 74FCT family, which bridges Fast CMOS speed with TTL-compatible input levels. The CY74FCT823 variant specifically addresses applications needing multi-bit latching with controlled output impedance. It serves as a core building block for synchronous digital logic designs requiring reliable data retention and bus management capabilities.

Replacement Considerations

Consult official cross-reference guides for equivalent 9-bit D-type flip-flops with tri-state outputs from other manufacturers. Verify pin compatibility and electrical specifications such as output drive strength and propagation delay before substituting.
