CY74FCT2245CTSOC

Overview

The CY74FCT2245CTSOC 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 three-state outputs with 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 across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission via eight independent channels
• Features non-inverting logic polarity for signal integrity
• Supports three-state outputs to prevent bus contention

Applications

• High-speed data bus architectures
• Memory-to-memory or memory-to-I/O transfers
• Buffering applications requiring isolation

Procurement Notes

Verify the specific suffix 'CTSOC' against the manufacturer's official datasheet to confirm the tube packaging configuration and commercial grade temperature rating. Ensure compatibility with standard SOIC-20 footprints during PCB layout. Cross-reference RoHS compliance status directly with the latest component documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring fast switching speeds with moderate drive capability. The 4.6 ns propagation delay suits high-frequency digital interfaces. Compare the 12 mA/15 mA output currents against load requirements to ensure adequate noise margins without exceeding thermal limits in dense circuit board layouts.

Part Context

This part belongs to the CY74FCT2245T family of octal bus transceivers manufactured by Texas Instruments. It shares functional similarities with other FCT series devices but is distinguished by its specific pinout and electrical characteristics optimized for standard TTL-compatible logic families in commercial electronic applications.

Replacement Considerations

The CY74FCT2245ATSOC serves as a verified alternative within the same product family, offering identical functionality with potential variations in temperature rating or packaging.
