CY74FCT2827ATQCTG4

Overview

The CY74FCT2827ATQCTG4 is a 10-bit buffer and line driver manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes CMOS technology. The device features non-inverting polarity with 3-state outputs, providing high-level output current of -15 mA and low-level output current of 12 mA. It operates within a supply voltage range of 4.75 V to 5.25 V and exhibits a propagation delay of 10 ns. The component is housed in a QSOP-24 package, supports surface mount installation, and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides ten independent non-inverting signal paths for buffering and driving applications
• Features three-state outputs to facilitate bus-oriented architectures and system isolation
• Delivers strong drive capability suitable for interfacing with various digital loads

Applications

• High-speed data bus buffering in computer systems
• Signal conditioning for memory interface circuits
• Line driving for parallel communication links

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the package type matches the QSOP-24 footprint requirements for your PCB layout. Ensure the operating environment stays within the specified -40°C to +85°C temperature range to maintain performance integrity. Cross-reference the datasheet for exact pinout configurations before integration.

Selection Notes

Select this component when ten-channel buffering with high drive strength is required. The FCT series offers compatibility with standard TTL and CMOS logic levels. Consider the 10 ns propagation delay for timing-sensitive designs. The 3-state output allows multiple drivers on a shared bus without contention. Verify power supply stability within the 4.75 V to 5.25 V window for optimal operation.

Part Context

This part is part of the broader 74FCT family of high-speed CMOS logic devices. It serves as a specialized buffer solution within Texas Instruments' portfolio of linear and logic ICs. The device complements other FCT components like transceivers and latches by providing dedicated unidirectional signal path management for complex digital systems requiring robust signal integrity.

Replacement Considerations

Check for CY74FCT2827T variants or equivalents from other manufacturers offering identical 10-bit FCT specifications. Ensure any substitute maintains the QSOP-24 package dimensions and electrical characteristics. Verify that alternative parts support the same 3-state output functionality and voltage ranges.
