Low-Voltage Octal Bus Buffer with 5-V Tolerant Inputs and Outputs

The TC74LCX541 is a high-performance CMOS octal bus

buffer. Designed for use in 3.3-V systems, it achieves high-speed

operation while maintaining the CMOS low power dissipation.

The device is designed for low-voltage (3.3 V) VCC applications,

but it could be used to interface to 5 V supply environment for

both inputs and outputs.

The TC74LCX541 is a non-inverting 3-state buffer having two

active-low output enables. When either OE1 or OE2 are high,

the terminal outputs are in the high-impedance state. This device

is designed to be used with 3-state memory address drivers, etc.

All inputs are equipped with protection circuits against static

discharge.

Features
