CY74FCT541TSOCT

Overview

The CY74FCT541TSOCT 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, high-level output current of -32 mA, and low-level output current of 64 mA. Static current is specified at 200 nA, with a maximum operating temperature of +85 C.

Feature Summary

• Provides tri-state control for bidirectional bus monitoring or temporary disconnection from system lines
• Delivers high drive capability suitable for driving capacitive loads and transmission lines
• Ensures signal integrity through fast switching speeds and low static power consumption

Applications

• Clock distribution networks requiring buffered signals
• Memory address and data bus drivers
• Control signal buffering in industrial systems

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when sourcing. Confirm the 'C' grade corresponds to commercial temperature ratings. Ensure the manufacturer designation matches Texas Instruments specifications for the CY74FCT541T series to avoid counterfeit components.

Selection Notes

Select this component for applications requiring octal buffering with high drive strength. Compare against the CY74FCT240T if inverting functionality is needed instead. Consider the CY74FCT2541TQCTE4 for alternative QSOP packaging options while maintaining similar electrical characteristics.

Part Context

This part belongs to the Texas Instruments CY74FCT541T family of octal buffers. It shares functional similarities with other FCT series devices but offers specific pinout and drive characteristics optimized for standard SOIC mounting. The device supports CMOS logic levels with TTL-compatible input thresholds.

Replacement Considerations

Direct substitutes include the CY74FCT541ATSOC and CY74FCT541CTSOC for equivalent performance in different packaging or grade variations.
