CY74FCT2245ATSOCT

Overview

The CY74FCT2245ATSOCT is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features a single non-inverting element with eight bits per element and three-state outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports TTL input and output levels. It exhibits a propagation delay of 4.6 ns, with low-level output current of 12 mA and high-level output current of -15 mA. Designed for surface mount installation, it is housed in a 20-SOIC package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability via a single control element
• Three-state outputs enable direct system bus interconnection without additional drivers
• TTL-compatible input and output voltage levels ensure interface compatibility

Applications

• High-speed memory bus architectures requiring bidirectional data flow
• System clock distribution networks utilizing non-inverted signal paths
• Address bus drivers in complex digital processing systems

Procurement Notes

Verify the manufacturer designation carefully, as this component is frequently listed under Texas Instruments despite the Cypress part number prefix. Confirm the specific suffix 'CT' indicates tape and reel packaging rather than tube configuration. Ensure the datasheet corresponds to the FCT2245T family specifications to validate electrical characteristics and pinout alignment before integration into design files.

Selection Notes

Select this component when an octal, non-inverting transceiver with TTL compatibility is required for bidirectional data routing. The FCT series offers faster switching speeds compared to standard LS logic while maintaining similar power consumption profiles. Verify that the 20-SOIC package dimensions fit the available PCB footprint and that the 4.75V to 5.25V operating range matches the target system power supply rails.

Part Context

This device belongs to the 74FCT2245 family of octal bus transceivers. It serves as a critical interface component for managing data flow between microprocessors and peripheral devices. The FCT technology combines CMOS density with TTL speed, making it suitable for applications demanding high performance in standard logic environments. The SOIC-20 package provides a compact solution for dense circuit board layouts.
