CY74FCT2574ATSOCT

Overview

The CY74FCT2574ATSOCT is an octal bus transceiver manufactured by Texas Instruments, belonging to the FCT logic series. It features single-ended inputs and outputs with a non-inverting polarity configuration. The device operates within a supply voltage range of 4.75 V to 5.25 V. It exhibits a propagation delay of 6.5 ns, with high-level output current capability of -15 mA and low-level output current of 12 mA. Packaged in a SOIC-20 form factor, this component is currently marked as obsolete.

Feature Summary

• Octal bus transceiver architecture providing eight independent data channels
• Three-state outputs for effective bus line isolation and management
• Single-ended input and output signal interface design

Applications

• Bus-oriented memory and register implementations
• Clock drivers requiring controlled transfer characteristics
• Bidirectional bus architectures utilizing three-state control

Procurement Notes

This specific part number is officially classified as obsolete by the manufacturer. Verification of availability should focus on alternative package options or direct replacement components rather than original stock. Confirming the exact functional equivalent is essential before procurement planning.

Selection Notes

Designers must evaluate the transition from the obsolete ATSOCT variant to available alternatives. Key selection criteria include verifying pin compatibility and ensuring that the replacement maintains the required 6.5 ns propagation delay and 3-state output specifications for the target application.

Part Context

As part of the FCT family, this component bridges CMOS and TTL logic levels. The octal configuration allows for efficient handling of wide data buses. Its design supports standard industrial temperature ranges and provides reliable performance for general-purpose digital logic applications.
