CY74FCT2245TSOCTE4

Overview

The CY74FCT2245TSOCTE4 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 provides TTL-compatible input and output levels with a propagation delay of 7 ns. It supports low-level output currents of 12 mA and high-level output currents of -15 mA. Designed for surface-mount installation, it is housed in a 20-pin SOIC package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability with common control
• Tri-state outputs for effective bus line isolation
• TTL-compatible input and output voltage levels

Applications

• High-speed data bus architectures
• Memory module interfacing
• Buffering and bus driving applications

Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's current datasheet to confirm compliance details and pinout consistency. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements. Confirm that the 4.75V to 5.25V supply voltage range aligns with the system power design specifications before finalizing procurement.

Selection Notes

Select this component when an octal, non-inverting bus transceiver with tri-state functionality is required for 5V logic systems. The FCT series offers faster switching speeds compared to standard LS logic. Consider the 20-pin SOIC package for surface-mount assembly constraints. Verify that the 7 ns propagation delay meets the timing requirements of the specific bus interface application.

Part Context

This part belongs to the Texas Instruments CY74FCT family of fast CMOS logic devices. The FCT series is designed to provide performance comparable to Schottky TTL while maintaining CMOS power consumption characteristics. The CY74FCT2245 variant specifically addresses applications requiring wide data path buffering and direction control on shared communication buses.
