CY74FCT273ATQCT

Overview

The CY74FCT273ATQCT is an octal D-type flip-flop with clear, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features TTL-compatible inputs with CMOS outputs. The device provides non-inverting logic and includes a master reset function. Key electrical parameters include a propagation delay of 7.2 ns at 50 pF load, high-level output current of 32 mA, and low-level output current of 64 mA. Static current (Iq) is specified at 200 µA. It is housed in a 20-SSOP package and supports surface mount installation.

Feature Summary

• Octal D-type flip-flop architecture with integrated clear functionality
• TTL-compatible input levels interfacing with CMOS output drivers
• Master reset capability for synchronous data control

Applications

• Parallel-to-serial data conversion circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) prior to soldering. Ensure packaging integrity matches reel or cut-tape specifications required for automated assembly processes. Cross-reference ordering suffixes to confirm exact package variant and temperature grade alignment with design requirements.

Selection Notes

Select this component when designing systems requiring octal storage with TTL input compatibility. Consider the 20-SSOP package dimensions for PCB layout constraints. Evaluate thermal performance within the -40°C to +85°C operating range. Compare propagation delay characteristics against system timing budgets to ensure signal integrity across all eight channels.

Part Context

This part belongs to the Texas Instruments 74FCT logic family, which combines BiCMOS technology for high-speed performance with low power consumption. The 74FCT273 series specifically addresses applications needing parallel data storage with fast switching speeds. It serves as a standard solution for digital logic interfaces requiring reliable data retention and quick response times in industrial and consumer electronics.

Replacement Considerations

CY74FCT273CTQCT offers similar functionality but may differ in specific electrical characteristics or package tolerances. Verify pinout compatibility and parameter equivalence before substitution. Consult official datasheets for detailed comparison of propagation delays and drive strengths to ensure functional parity in existing designs.
