CY74FCT2245ATSOCT

Overview

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

Feature Summary

• Octal configuration providing eight bidirectional data paths for efficient bus interfacing
• Three-state outputs enable direct connection to system buses without additional drivers
• Non-inverting polarity maintains signal integrity during data transmission

Applications

• High-speed data bus architectures requiring bidirectional transfer
• Memory module interfaces in computing systems
• Industrial control systems utilizing TTL-compatible logic levels

Procurement Notes

Verify the specific suffix 'CT' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required operating temperature range and electrical specifications for the target application environment.

Selection Notes

Select this component for applications demanding high-speed data transfer with minimal propagation delay. The FCT series offers improved performance over standard 74F logic while maintaining compatibility with existing TTL designs. Consider the SOIC-20 package dimensions for PCB layout constraints and thermal management requirements.
