54LCX16244
Low Voltage 16-Bit Buffer/Line Driver with 5V Tolerant
Inputs and Outputs
General Description
The LCX16244 contains sixteen non-inverting buffers with
TRI-STATE^® outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmitter/
receiver. The device is nibble controlled. Each nibble has
separate TRI-STATE control inputs which can be shorted to-
gether for full 16-bit operation.
The LCX16244 is designed for low voltage (3.3V) V_CC appli-
cations with capability of interfacing to a 5V signal environ-
ment.
The LCX16244 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
