Low?Voltage CMOS 16?Bit Buffer

With 5 V?Tolerant Inputs and Outputs (3?State, Non?Inverting)

The MC74LCX16244 is a high performance, non?inverting 16?bit buffer operating from a 2.3 to 3.6 V supply. The device is nibble controlled. Each nibble has separate Output Enable inputs which can be tied together for full 16?bit operation. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX16244 inputs to be safely driven from 5.0 V devices. The MC74LCX16244 is suitable for memory address driving and all TTL level bus oriented transceiver applications.
