CY74FCT245ATSOCT

Overview

The CY74FCT245ATSOCT is an octal bus transceiver from the Texas Instruments FCT logic series, housed in a 20-pin SOIC 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, three-state outputs with a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 7 ns. It functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability for system interconnects
• Three-state outputs enable direct connection to system buses without additional drivers
• TTL-compatible input and output voltage levels ensure interface compatibility

Applications

• High-performance memory mapping systems
• Clock drivers and buffer circuits
• Bus-oriented architectures requiring bidirectional data flow

Procurement Notes

Verify the specific suffix 'TSOCT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and lead-free status. Ensure the order matches the required 20-SOIC form factor and that the component meets RoHS compliance standards as defined in the latest product change notices.

Selection Notes

Select this component when an octal, non-inverting transceiver with TTL-compatible I/O is required for 5V logic systems. The FCT series offers faster switching speeds compared to standard CMOS alternatives. Confirm that the 7 ns propagation delay and 64 mA drive strength meet the specific timing and load requirements of the target application design.
