74LCX162244
Low Voltage 16-Bit Buffer/Line Driver
with 26Ω Series Resistors in Outputs
General Description
The LCX162244 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 LCX162244 is designed for low voltage (2.5V or 3.3V)
V
CC
applications with capability of interfacing to a 5V signal
environment.
In addition, the outputs include equivalent 26Ω (nominal)
series resistors to reduce overshoot and undershoot and
are designed to sink/source up to 12 mA at V
CC
= 3.0V.
The LCX162244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
