74LVT162240 • 74LVTH162240

Low Voltage 16-Bit Inverting Buffer/Line Driver

with 3-STATE Outputs and

25

: Series Resistors in the Outputs

General Description

The LVT162240 and LVTH162240 contain sixteen inverting

buffers with 3-STATE outputs designed to be employed as

a memory and address driver, clock driver, or bus oriented

transmitter/receiver. The device is nibble controlled. Indi-

vidual 3-STATE control inputs can be shorted together for

8-bit or 16-bit operation.

The LVT162240 and LVTH162240 are designed with

equivalent 25

: series resistance in both the HIGH and

LOW states of the output. This design reduces line noise in

applications such as memory address drivers, clock driv-

ers, and bus transceivers/transmitters.

The LVTH162240 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

These inverting buffers and line drivers are designed for

to provide a TTL interface to a 5V environment. The

LVT162240 and LVTH162240 are fabricated with an

advanced BiCMOS technology to achieve high speed oper-

ation similar to 5V ABT while maintaining a low power dis-

sipation.

Features

s Input and output interface capability to systems at

s Outputs include equivalent series resistance of 25

: to

make external termination resistors unnecessary and

reduce overshoot and undershoot

s Bushold data inputs eliminate the need for external

pull-up resistors to hold unused inputs (74LVTH162240),

also available without bushold feature (74LVT162240)

s Live insertion/extraction permitted

s Power Up/Down high impedance provides glitch-free

bus loading

s Functionally compatible with the 74 series 162240

s Latch-up performance exceeds 500 mA

s ESD performance:
