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

The TC74LCX540 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.

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

both inputs and outputs.

The TC74LCX540 is an inverting 3-state buffer having two

active-low output enables. When either

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

• Latch-up performance: −500 mA

• Available in JEITA SOP, TSSOP and VSSOP (US)

• Power-down protection provided on all inputs and outputs

• Pin and function compatible with the 74 series

(74AC/VHC/HC/F/ALS/LS etc.) 540 type
