CY74FCT273CTSOC

Overview

The CY74FCT273CTSOC is an octal D-type flip-flop register manufactured by Texas Instruments. It features a single circuit with eight non-inverting inputs and outputs, housed in a SOIC-20 surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. Key electrical parameters include a propagation delay of 5.8 ns, high-level output current of -32 mA, and low-level output current of 64 mA. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop configuration with integrated clear functionality
• CMOS output structure compatible with TTL input logic levels
• Non-inverting signal path for direct data transfer applications

Applications

• Parallel-to-serial data conversion circuits
• General-purpose digital storage registers
• High-speed interface buffering systems

Procurement Notes

Verify the specific suffix CT against official Texas Instruments documentation to confirm pinout compatibility and package dimensions. Ensure that the operating environment remains within the specified -40°C to +85°C range to maintain performance integrity. Cross-reference the datasheet revision history to validate any changes in mechanical outline or electrical characteristics prior to finalizing procurement orders.

Selection Notes

Select this component when an octal register with a dedicated clear function is required for synchronous data capture. The FCT series offers superior switching speeds compared to standard 74-series logic. Consider the SOIC-20 package constraints and thermal dissipation requirements during PCB layout design to ensure reliable operation under maximum load conditions.

Part Context

This part belongs to the CY74FCT273T family of BiCMOS logic devices. It serves as a high-performance alternative to legacy transistor-transistor logic families. The FCT technology combines the speed of bipolar transistors with the power efficiency of CMOS, making it suitable for demanding digital system architectures requiring fast clock rates.
