74LCX244FT

1. Functional Description

•

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

2. General

The 74LCX244FT 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 74LCX244FT is a non-inverting 3-state buffer having

two active-low output enables. 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 V)

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

(5) Pin and function compatible with the 74 series

(74LVC/ALVC/ etc.) 244 type

4. Packaging
