Description

The 74LCXZ16244 contains sixteen non-inverting buffers with 3-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 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 oriented applications.
The 74LCXZ16244 is designed for low voltage (2.7V or 3.3V) V_CC applications with capability of interfacing to a 5V signal environment.
The 74LCXZ16244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
