74LCXZ16244
Low Voltage 16-Bit Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
General Description
The LCXZ16244 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 LCXZ12644 is in the
high impedance state during power up or power down. This
places the outputs in high impedance (Z) state preventing
intermittent low impedance loading or glitching in bus ori-
ented applications.
The LCXZ16244 is designed for low voltage (2.7V or 3.3V)
V_CC applications with capability of interfacing to a 5V signal
environment.
The LCXZ16244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
