74LVT16240 鈥?74LVTH16240
Low Voltage 16-Bit Inverting Buffer/Line Driver
with 3-STATE Outputs
General Description
The LVT16240 and LVTH16240 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.
Individual 3-STATE control inputs can be shorted together
for 8-bit or 16-bit operation.
The LVTH16240 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 LVT16240 and
LVTH16240 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining a low power dissipation.
