CY74FCT245TSOCT

Overview

The CY74FCT245TSOCT is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features a single non-inverting circuit with eight channels and three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. Key electrical parameters include a propagation delay of 7 ns, a low-level output current of 64 mA, and a high-level output current of -32 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability with common control direction pins
• Three-state outputs for effective bus line driving and isolation
• TTL-compatible input and output voltage levels for system integration

Applications

• High-speed data bus architectures requiring octal buffering
• Memory-to-memory or memory-to-I/O data transfers
• Clock drivers and buffer circuits in digital systems

Procurement Notes

Verify the specific suffix 'TSOCT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and lead-free status. Ensure the ordering part number matches the required package type and environmental compliance specifications before finalizing procurement orders.

Selection Notes

Select this component when an octal, non-inverting bus transceiver with FCT speed characteristics is required. It is suitable for designs needing 7 ns propagation delay and strong drive currents. Compare against similar parts like the CY74FCT245ATSOCT if different packaging options are needed.

Part Context

This part belongs to the Texas Instruments CY74FCT245T family of standard bus transceivers. It shares functional similarities with other members of the 74FCT series but is distinguished by its specific SOIC-20 surface-mount package and commercial/industrial temperature rating.

Replacement Considerations

The CY74FCT245ATSOCT is a documented substitute within the same product family, offering identical logical functionality.
