CY74FCT541CTSOCT

Overview

The CY74FCT541CTSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.1 ns at 5 V, a high-level output current of -32 mA, and a low-level output current of 64 mA. Static current consumption is specified at 200 nA, while operating power current reaches 3.3 mA. The component supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix 'CTSOCT' against official Texas Instruments documentation to confirm the exact tape and reel packaging configuration and moisture sensitivity level. Ensure the order matches the required SOIC-20 footprint and lead finish specifications defined in the latest datasheet revision to avoid assembly discrepancies.

Selection Notes

Select this component when designing systems requiring high-speed octal buffering with three-state control. It is appropriate for applications needing compatibility between CMOS and TTL logic families. Consider the 20-SOIC package constraints and thermal characteristics relative to the intended operating environment and board layout requirements.

Part Context

This part belongs to the CY74FCT541T family of octal buffers and line drivers. It serves as a standard solution for expanding bus capabilities in digital circuits. The FCT series is designed to bridge the performance gap between older bipolar technologies and modern CMOS solutions, offering faster switching speeds than legacy counterparts while maintaining low power consumption.

Replacement Considerations

Cross-reference with CY74FCT541ATSOC or CY74FCT541ATQCT for alternative pin-compatible options from Texas Instruments. Verify that any substitute maintains the same 20-pin SOIC or SSOP form factor and identical electrical characteristics to ensure seamless integration without circuit redesign.
