CY74FCT2374CTSOC

Overview

The CY74FCT2374CTSOC is an octal transparent D-type latch manufactured by Texas Instruments. It features three-state outputs and integrated series damping resistors to minimize signal reflections. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL-compatible inputs. It is housed in a 20-pin SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal transparent D-type latch architecture with eight data inputs and corresponding outputs.
• Integrated series damping resistors designed to reduce signal ringing and reflections on high-speed buses.
• Three-state output capability allowing direct connection to bus structures for efficient data multiplexing.

Applications

• High-speed parallel data buffering in telecommunications equipment.
• Clocked memory interface circuits requiring controlled signal integrity.
• Bus-oriented logic systems utilizing FCT technology for improved performance.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'CSOC' matches project requirements, as it denotes the SOIC-20 package variant. Check for obsolescence status, as this part may be discontinued. Ensure ESD handling protocols are followed during storage and assembly to prevent damage to sensitive CMOS inputs.

Selection Notes

Select this component when designing systems that require transparent latching behavior rather than edge-triggered storage. The inclusion of series damping resistors makes it suitable for applications where signal integrity is critical without external termination components. Compare propagation delay specifications against system timing budgets to ensure compatibility with clock frequencies.

Part Context

This device belongs to the CY74FCT family, which combines CMOS density with Schottky TTL speed. It serves as a latch variant within the broader FCT logic portfolio, distinct from standard flip-flops like the CY74FCT374 due to its transparent nature. The SOIC-20 package provides a compact footprint for surface-mount assembly in dense PCB layouts.

Replacement Considerations

Public confirmed substitute part numbers: None identified in verified documentation. Note that the CY74FCT2374CTSOC is listed as obsolete in some distributor records; verify current availability and lifecycle status before finalizing designs.
