Overview
The CY74FCT823CTQC is a 9-bit D-type flip-flop bus driver from Texas Instruments' FCT logic series. It features tri-state outputs and operates within a 4.75V to 5.25V supply range. The device provides a maximum propagation delay of 12.5ns at 5V with 300pF load. Output drive capabilities include 32mA high-level and 64mA low-level currents. It utilizes a 24-pin SSOP/QSOP package and supports surface mount installation across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates nine D-type flip-flops with positive-edge clock triggering for data storage and transfer.
- Provides tri-state output control to manage bus line contention in multi-driver systems.
- Delivers high-current drive capability suitable for direct interface with buses and loads.
Applications
- High-speed parallel data buffering and latching in communication interfaces
- Register stages in digital signal processing architectures
- Bus driver applications requiring controlled output impedance
Procurement Notes
Verify the specific suffix 'CTQC' against official Texas Instruments documentation to confirm pinout, voltage tolerance, and package dimensions. Ensure the component meets required environmental specifications for the target operating temperature range. Confirm that the manufacturer designation aligns with current production status, as availability may vary by source.
Selection Notes
Select this component when a 9-bit wide register with tri-state output is required. Consider the 12.5ns propagation delay for timing constraints. Evaluate the 24-SSOP/QSOP package size against board space limitations. Compare power consumption and drive strength against alternative FCT series devices if system efficiency is critical.
Part Context
This part belongs to the CY74FCT823T family of fast CMOS logic devices. It is designed for high-speed applications requiring low power dissipation. The FCT series bridges TTL and CMOS compatibility, allowing integration into mixed-logic systems while maintaining performance standards typical of advanced semiconductor manufacturing.
Replacement Considerations
Consult official substitution lists for equivalent 9-bit D-type flip-flops with tri-state outputs. Verify pin compatibility and electrical parameters before replacing. Generic equivalents may differ in propagation delay or drive strength.
