74LVTH162244
Low Voltage 16-Bit Buffer/Line Driver
with 3-STATE Outputs
and 25 Series Resistors in the Outputs
General Description
The LVT162244 and LVTH162244 contain sixteen non-
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 con-
trolled. Individual 3-STATE control inputs can be shorted
together for 8-bit or 16-bit operation.
The LVT162244 and LVTH162244 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 LVTH162244 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These buffers and line drivers are designed for low-voltage
(3.3V) V
CC
applications, but with the capability to provide a
TTL interface to a 5V environment. The LVT162244 and
LVTH162244 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining a low power dissipation.

Bushold data inputs eliminate the need for external pull-
up resistors to hold unused inputs (74LVTH162244),
also available without bushold feature (74LVT162244).
