CY74FCT374ATQCT

Overview

The CY74FCT374ATQCT is an octal D-type flip-flop with 3-state outputs belonging to the FCT logic series. It operates within a supply voltage range of 4.75 V to 5.25 V and features TTL-compatible inputs. The device provides non-inverting data transfer triggered by the positive edge of the clock signal. It supports live insertion through power-off disabled outputs. The component is housed in a 20-pin QSOP package with a lead pitch of 0.150 inches. It functions reliably across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Provides octal storage with positive-edge triggering for synchronous data capture
• Features 3-state outputs that disable during power-off to permit live insertion
• Accepts TTL-compatible input signals for direct interfacing with standard logic families

Applications

• High-density memory register implementations
• Buffering and bus-oriented organizational circuits
• Clock domain crossing synchronization stages

Procurement Notes

Verify the manufacturer designation, as documentation sources attribute this part number to both Cypress Semiconductor and Texas Instruments. Confirm the specific RoHS compliance status and lead content requirements against the current datasheet revision. Ensure the ordering suffix matches the required tape-and-reel packaging configuration for automated assembly processes.

Selection Notes

Select this component when an octal storage element with high-speed performance and TTL input compatibility is required. The 3-state output capability allows for efficient bus sharing in complex digital systems. Consider the QSOP package dimensions and thermal characteristics for PCB layout constraints. Verify that the operating voltage range aligns with the system's 5V power distribution network.

Part Context
