CY74FCT2245TSOCT

Overview

The CY74FCT2245TSOCT is an octal bus transceiver manufactured by Texas Instruments, belonging to the FCT logic series. It features tri-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides eight channels with TTL input and output levels. Key electrical parameters include a propagation delay of 7 ns, a low-level output current of 12 mA, and a high-level output current of -15 mA. It is housed in a 20-pin SOIC package and supports surface-mount installation. The component functions as a non-inverting transceiver suitable for standard digital applications.

Feature Summary

• Octal bus transceiver architecture providing bidirectional data transfer across eight channels
• Tri-state output capability allowing effective bus isolation and system management
• TTL-compatible input and output voltage levels ensuring interface compatibility

Applications

• High-speed data transmission on parallel buses
• Memory buffer interfaces in computing systems
• I/O port expansion for microcontroller-based designs

Procurement Notes

Verify the manufacturer designation carefully, as official documentation lists Texas Instruments as the producer for this part number despite the query specifying Cypress Semiconductor Corp. Confirm the specific suffix 'TSOCT' corresponds to the SOIC-20 package and reel/cut-tape packaging options. Ensure compliance with RoHS standards and check for any recent product change notices regarding material or assembly updates before finalizing procurement orders.

Selection Notes

Select this component when an octal width is required for bus interfacing rather than the hex configuration found in similar FCT devices. The 7 ns propagation delay offers adequate speed for many general-purpose digital systems. Consider the 20-pin SOIC footprint for PCB layout constraints. Verify that the 4.75 V to 5.25 V operating range aligns with the target system's power supply rails.

Part Context

This device is part of the broader 74FCT2245 family of octal bus transceivers. It shares functional similarities with other FCT series components but is distinguished by its specific pinout and electrical characteristics. The part serves as a critical interface element between different logic domains or memory subsystems in electronic circuits requiring reliable bidirectional data flow.

Replacement Considerations

Publicly confirmed substitute part numbers include CY74FCT2245ATSOCT and CY74FCT2245ATPWR. These alternatives maintain the same logical function and pinout compatibility.
