CY74FCT2245TSOCT

Overview

The CY74FCT2245TSOCT is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features tri-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports TTL input and output levels with a propagation delay of 7 ns. It provides a low-level output current of 12 mA and a high-level output current of -15 mA. Packaged in a 20-SOIC format, it functions as a non-inverting transceiver suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability with tri-state outputs
• TTL-compatible input and output voltage levels
• Non-inverting signal polarity for direct data routing

Applications

• High-speed data bus architectures requiring octal width
• Memory-to-memory or memory-to-I/O data transfers
• System control signal routing in industrial environments

Procurement Notes

Verify the specific suffix 'TSOCT' against the manufacturer's official datasheet to confirm package type (SOIC-20) and tape-and-reel configuration. Ensure compatibility with 5V logic systems given the 4.75V to 5.25V operating range. Confirm RoHS compliance status through the latest component documentation before integration into production designs.

Selection Notes

Select this component when an octal, non-inverting bus interface is required with TTL level compatibility. The 7 ns propagation delay suits moderate-speed digital systems. Compare against the CY74FCT2245AT variant if A-grade specifications are needed. Ensure the 20-SOIC footprint matches the PCB layout constraints and that the 12 mA/15 mA drive currents meet load requirements.

Part Context

This part belongs to the CY74FCT2245T family of standard bus transceivers. It shares functional similarities with other FCT series devices like the CY74FCT245 but differs in specific electrical characteristics such as drive strength and delay times. The SOIC-20 package is common for this logic family, facilitating automated assembly in consumer and industrial electronics.

Replacement Considerations

The CY74FCT2245ATSOCT is a documented substitute within the same product line. Verify pinout and electrical parameter equivalence before substitution.
