74LVT16244 74LVTH16244
Low Voltage16-Bit Buffer/Line Driver
with 3-STATE Outputs
General Description
The LVT16244 and LVTH16244 contain sixteen non-invert-
ing buffers with 3-STATE outputs designed to be employed
as a memory and address driver, clock driver, or bus ori-
ented transmitter/receiver. The device is nibble controlled.
Individual 3-STATE control inputs can be shorted together
for 8-bit or 16-bit operation.
The LVTH16244 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 LVT16244 and
LVTH16244 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining a low power dissipation
