IDT74FCT374ATPY8

Flip Flops Overview

The IDT74FCT374ATPY8 is an octal D-type flip-flop manufactured by Renesas Electronics Corporation, belonging to the 74FCT logic series. It features positive-edge triggering and non-inverting outputs with a three-state capability. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 10 MHz. Key electrical parameters include a propagation delay of 6.5 ns at 5V with a 50pF load, low-level output current of 48 mA, and high-level output current of -15 mA. It is housed in a 20-SSOP package (5.30mm width) and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

Flip Flops Procurement Notes

This component is officially designated as obsolete and no longer manufactured by Renesas Electronics Corporation. Procurement must rely on existing stock from authorized distributors or secondary market suppliers. Verify part authenticity and condition carefully, as original factory production has ceased. Cross-reference replacement options such as CY74FCT374ATQCT or CY74FCT374TQCT from Texas Instruments if new production units are required for ongoing designs.

Flip Flops Selection Notes

Select this component only for legacy system maintenance or repair where specific pinout and timing characteristics are mandatory. Due to its obsolete status, it is unsuitable for new design-in projects requiring long-term supply stability. Evaluate alternative FCT-series devices from other manufacturers that offer equivalent electrical performance and compatible packaging to ensure future availability and supply chain resilience.

Flip Flops Part Context

The IDT74FCT374ATPY8 belongs to the broader 74FCT family of high-speed CMOS logic devices originally developed by Integrated Device Technology (IDT), now part of Renesas Electronics. This specific part number denotes the octal D-flip-flop variant in a 20-lead SSOP package. The FCT series was designed to bridge the speed gap between standard TTL and ECL logic families, offering fast switching times while maintaining CMOS power efficiency.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include CY74FCT374ATQCT and CY74FCT374TQCT from Texas Instruments. These alternatives provide similar functional characteristics and may serve as drop-in replacements depending on specific board layout and timing requirements.
