74LCX540FT

1. Functional Description

•

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

2. General

The 74LCX540FT 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 74LCX540FT is an 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.

3. Features

(1) Low-voltage operation: VCC = 1.65 to 3.6 V

(2) High-speed operation: tpd = 6.5 ns (max) (VCC = 3.0 to 3.6 V)

(3) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 to 3.6 V)

(4) Power-down protection provided on all inputs and outputs

(5) Pin and function compatible with the 74 series

(74LVC/ALVC/ etc.) 540 type

4. Packaging
