MN54LCX16244-X REV 0A0 MICROCIRCUIT DATA SHEET
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 together for full 16-bit operation. The
device is designed for low voltage (3.3V) Vcc applications with capability of interfacing
to a 5V signal environment.
The LCX16244 is fabricated with an advanced CMOS technology to achieve high speed
operation while maintaining CMOS low power dissipation.
