74LCXZ162244
Low Voltage 16-Bit Buffer/Line Driver with 5V Tolerant
Inputs/Outputs and 26Ω Series Resistors in the Outputs
General Description
The LCXZ162244 contains sixteen non-inverting buffers
with 3-STATE outputs designed to be employed as a mem-
ory and address driver, clock driver, or bus oriented trans-
mitter/receiver. The device is nibble controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
When V
CC
is between 0 and 1.5V, the LCXZ162244 is in
the high impedance state during power up or power down.
this places the outputs in the high impedance (Z) state pre-
venting intermittent low impedance loading or glitching in
bus oriented applications.
The LCXZ162244 is designed for low voltage (2.7V or
3.3V) V
CC
applications with capability of interfacing to a 5V
signal environment.
In addition the outputs include 26Ω (nominal) series resis-
tors to reduce overshoot and undershoot and are designed
to sink/source 12 mA at V
CC
= 3.0V.
The LCXZ162244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
