TC74LVX240FTEL

Overview

The TC74LVX240FTEL is an octal bus buffer featuring inverted, three-state outputs. It operates within a supply voltage range of 2.0 V to 3.6 V and supports input voltages up to 5.5 V regardless of the supply level. The device provides balanced propagation delays with a typical value of 4.7 ns at 3.3 V. It includes power-down protection on all inputs and maintains low quiescent current.

Feature Summary

• Provides high-speed operation suitable for low-voltage and battery-operated systems while maintaining CMOS low power dissipation.
• Features input protection circuits that allow 0 to 5.5 V application to input pins independent of the supply voltage.
• Includes power-down protection on all inputs to prevent device destruction due to mismatched supply and input voltages.

Applications

• Three-state memory address drivers
• Interfacing 5 V to 3 V systems
• Two supply system interfaces such as battery backup

Procurement Notes

Verify the specific package type against the datasheet, as the 'F' suffix indicates SOP-20 packaging while 'FT' denotes TSSOP-20. Confirm RoHS compliance status directly with Toshiba Semiconductor and Storage or authorized distributors, as environmental declarations are subject to change. Ensure design reviews align with the manufacturer's reliability handbook regarding derating concepts and operating conditions.

Selection Notes

Select this component when interfacing between 5 V and 3 V logic domains requiring bidirectional data transfer. The inverted output configuration distinguishes it from the non-inverting TC74LVX244 variant. Verify that the required input voltage levels do not exceed the 5.5 V maximum rating under any operating condition.

Part Context

This part belongs to the TC74LVX series of high-speed CMOS octal bus buffers manufactured by Toshiba Semiconductor and Storage. It is functionally compatible with the 74HC240/244 family but optimized for lower voltage operation. The device utilizes silicon gate CMOS technology to achieve high-speed performance with minimal power consumption.
