CY74FCT2374TSOCTE4

Overview

The CY74FCT2374TSOCTE4 is an octal D-type flip-flop with output registers and 3-state outputs manufactured by Texas Instruments. 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 logic functionality with a typical propagation delay of 10 ns at 5 V with a 50 pF load. It supports high drive currents, delivering -32 mA for high-level output and 64 mA for low-level output. Designed for surface-mount applications, it is housed in a 20-SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with dedicated output registers for data latching
• Three-state outputs enabling bus-oriented memory and clocked operations
• TTL-compatible input levels ensuring interoperability with standard logic families
• Integrated 25-ohm output series resistors to minimize transmission-line reflection noise

Applications

• Bus-oriented memory implementations requiring parallel data storage
• Clocked register designs for temporary data holding in digital systems
• High-speed data buffering applications utilizing 3-state bus architectures

Procurement Notes

Verify the specific suffix 'E4' corresponds to lead-free RoHS compliance requirements for your assembly process. Confirm that the SOIC-20 package dimensions match your PCB footprint constraints. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Cross-reference the datasheet for any updates regarding pinout compatibility with legacy FCT or F Logic devices before finalizing procurement.

Selection Notes

Select this component when an octal D-type flip-flop with registered outputs and 3-state capability is required. It is suitable for designs needing TTL input compatibility and moderate speed performance around 10 ns. Consider this part for applications where reducing transmission-line reflections via integrated series resistors is beneficial. It serves as a direct replacement for similar FCT family parts in new designs requiring surface-mount packaging.

Part Context

This component belongs to the Texas Instruments CY74FCT family, which combines Fast CMOS technology with Schottky TTL-like switching speeds. The 2374 variant specifically integrates output registers, distinguishing it from simple latch variants. It is part of the broader 74FCT logic line designed for high-density digital applications requiring reliable data storage and bus management capabilities in compact surface-mount packages.
