CY74FCT273CTSOCTG4

Overview

The CY74FCT273CTSOCTG4 is an octal D-type flip-flop with a clear input, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features TTL-compatible inputs with CMOS outputs. The device provides non-inverting logic in a 20-pin SOIC package. Key electrical parameters include a propagation delay of 5.8 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with dedicated clear functionality
• TTL-compatible input interface ensuring broad signal compatibility
• CMOS output stage designed for robust driving capabilities

Applications

• High-speed data storage systems requiring parallel bit retention
• Digital control circuits utilizing edge-triggered state management
• Bus interface modules needing reliable data latching operations

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and environmental adherence during sourcing. Confirm the CTSOC designation matches the required 20-SOIC package dimensions for PCB layout integration. Ensure the manufacturer identification aligns with Texas Instruments specifications to guarantee component authenticity and performance consistency in final assembly processes.

Selection Notes

Select this component when designing systems requiring eight-bit synchronous data capture with explicit reset control. The FCT series offers superior switching speeds compared to standard logic families. Evaluate the 5.8 ns propagation delay against system timing constraints. Consider the wide operating temperature range for industrial or automotive environments where thermal stability is critical for long-term reliability.

Part Context

This part belongs to the Texas Instruments 74FCT logic family, which bridges Bipolar and CMOS technologies. The CY74FCT273 variant specifically addresses applications needing multiple independent flip-flops in a single package. The G4 suffix denotes a green, lead-free product compliant with RoHS directives, supporting modern environmental manufacturing standards while maintaining legacy pinout compatibility.

Replacement Considerations

CY74FCT273CTSOC serves as the direct equivalent without the environmental suffix. CD74FCT273E represents a through-hole alternative in PDIP-20 packaging. CY74FCT273ATQCT offers the same logical function but utilizes SSOP packaging for different board space requirements.
