CY74FCT2245CTSOCT

Overview

The CY74FCT2245CTSOCT is an octal bus transceiver from the Texas Instruments FCT logic series, housed in a 20-pin SOIC package. It features tri-state outputs and non-inverting polarity with eight independent channels. 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, low-level output current of 12 mA, and high-level output current of -15 mA. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability via eight independent channels
• Tri-state outputs for effective bus line isolation
• Non-inverting signal transmission logic
• TTL-compatible input and output voltage thresholds

Applications

• High-speed data bus architectures
• Memory module interfacing
• I/O port expansion circuits
• Buffering applications in digital systems

Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm temperature grade and manufacturing specifications. Ensure the SOIC-20 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring octal bus direction control with FCT speed characteristics. It serves as a suitable alternative to standard 74FCT2245 devices. Consider the 7 ns propagation delay and 5V operation limits during circuit design to ensure signal integrity and power compatibility.

Part Context

This part belongs to the CY74FCT2245T family of bus transceivers manufactured by Texas Instruments. It shares functional similarities with other FCT series components but offers specific packaging and performance traits defined by the SOIC-20 form factor. The device integrates eight bits of buffering into a single integrated circuit.

Replacement Considerations

CY74FCT2245ATSOCT is a documented substitute offering similar functionality within the same product family.
