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.
