74LCX245FT

Overview

The Toshiba Semiconductor and Storage 74LCX245FT is a low-voltage CMOS octal bus transceiver designed for 3.3-V systems. It features bidirectional data transmission controlled by a single direction input and an enable pin to isolate busses. The device operates within a supply voltage range of 1.65 V to 3.6 V, with a propagation delay of 7 ns at 3.3 V. It provides 24 mA output drive capability in both high and low states. Packaged in a TSSOP-20 format, it supports operation from -40°C to +85°C.

Feature Summary

• Low-voltage CMOS technology optimized for 3.3-V system applications while maintaining compatibility with 5-V tolerant environments.
• Bidirectional octal bus transceiver architecture allowing two-way asynchronous communication between data buses.
• High-speed performance with low power dissipation characteristics inherent to CMOS logic families.

Applications

• High-speed data transmission in portable electronic devices
• Memory bus interfacing in consumer electronics
• General-purpose bidirectional data routing in embedded systems

Procurement Notes

Verify the specific suffix 'FT' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements as indicated in public documentation. Cross-reference the Mouser part number 757-74LCX245FTAE for accurate ordering details and availability status.

Selection Notes

Select this component when designing 3.3-V logic interfaces requiring bidirectional data flow. The 7 ns propagation delay suits moderate-speed applications. Verify that the 24 mA drive current meets load requirements. Consider the TSSOP-20 package constraints for PCB layout. Confirm voltage levels align with the 1.65 V to 3.6 V operating range.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic integrated circuits manufactured by Toshiba Semiconductor and Storage. The LCX family is characterized by its ability to operate at lower voltages than standard HC/HCT series while offering comparable speed. This specific model implements the standard 74LCX245 octal transceiver function.
