UNIT

74AL VT162442.5V/3.3V 16-bit buffer/driver (3-State)

FEATURES

•16-bit bus interface

•5V I/O compatibile

•3-State buffers

•Output capability: +64mA/-32mA

•TTL input and output switching levels

DESCRIPTION

The 74ALVT16244 is a high-performance BiCMOS product
designed for V
to 5V .

This device is a 16-bit buffer and line driver featuring non-inverting
3-State bus outputs. The device can be used as four 4-bit buffers,
two 8-bit buffers, or one 16-bit buffer.

operation at 2.5V or 3.3V with I/O compatibility up

CC

•Input and output interface capability to systems at 5V supply

•Bus-hold data inputs eliminate the need for external pull-up

resistors to hold unused inputs

•Live insertion/extraction permitted

•Power-up 3-State

•No bus current loading when output is tied to 5V bus

•Latch-up protection exceeds 500mA per JEDEC Std 17

•ESD protection exceeds 2000V per MIL STD 883 Method 3015

and 200V per Machine Model
