CY74FCT374ATPC

Overview

The CY74FCT374ATPC is an octal transparent D-type flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features three-state outputs. The device supports TTL input levels and provides non-inverting logic polarity. Key electrical specifications include a propagation delay of 6.5 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It is housed in a PDIP-20 package designed for through-hole mounting and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal transparent data storage with eight independent D-type flip-flops
• Three-state outputs allowing direct bus interfacing
• TTL-compatible input structure for robust signal reception
• Power-off disable capability to permit live insertion

Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching digital data lines
• Memory address register implementations
• General-purpose shift register configurations

Procurement Notes

Verify the specific suffix 'ATPC' corresponds to the PDIP-20 through-hole package variant when sourcing. Confirm that the manufacturer designation aligns with Texas Instruments, as Cypress Semiconductor was previously associated with this product line. Ensure compliance with RoHS directives if required for the target assembly process. Cross-reference the datasheet revision to confirm pinout consistency with existing board designs.

Selection Notes

Select this component when an octal latch with high drive capability and TTL compatibility is required. The 64 mA low-level output current supports moderate capacitive loads without external buffering. The wide operating temperature range suits industrial environments. Consider the PDIP-20 form factor for prototyping or applications requiring manual soldering. Evaluate power consumption requirements against the static current specifications provided in the official documentation.

Part Context

This part belongs to the FCT (Fast CMOS) logic family, bridging the performance gap between standard CMOS and Schottky TTL technologies. It offers high-speed operation comparable to LS-TTL while maintaining low power dissipation typical of CMOS devices. The CY74FCT374 series is widely used in embedded systems requiring reliable data retention and fast switching speeds.
