MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low-Voltage CMOS 16-Bit Buffer With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting) The MC74LCX16244 is a high performance, non–inverting 16–bit buffer operating from a 2.7 to 3.6V 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 5.5V allows MC74LCX16244 inputs to be safely driven from 5V devices. The MC74LCX16244 is suitable for memory address driving and all TTL level bus oriented transceiver applications. 4.5ns maximum propagation delays support high performance applications. Current drive capability is 24mA at the outputs. The Output Enable (OEn) inputs, when HIGH, disable the outputs by placing them in a HIGH Z condition.
