74LCX16244
Low Voltage 16-Bit Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
General Description
The LCX16244 contains sixteen non-inverting buffers with
3-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmit-
ter/receiver. The device is nibble controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The LCX16244 is designed for low voltage (2.5 or 3.3V)
V
CC
applications with capability of interfacing to a 5V signal
environment.
The LCX16244 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
