General Description
74LCXZ162244 General Description
The LCXZ162244 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 VCC 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 preventing intermittent low impedance loading or glitching in bus oriented applications.
The LCXZ162244 is designed for low voltage (2.7V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. In addition the outputs include 26Ω (nominal) series resistors to reduce overshoot and undershoot and are designed to sink/source 12 mA at VCC = 3.0V.
The LCXZ162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
