SEMICONDUCTOR TECHNICAL DATA

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

LOW–VOLTAGE

outputs offer improved switching noise performance. A V specification of

CMOS 16–BIT BUFFER

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.

Function

The MC74LCX16244 contains sixteen non–inverting buffers with

3–state 5V–tolerant outputs. The device is nibble controlled with each

nibble functioning identically, but independently. The control pins may be

tied together to obtain full 16–bit operation. The 3–state outputs are

controlled by an Output Enable (OEn) input for each nibble. When OEn is

LOW, the outputs are on. When OEn is HIGH, the outputs are in the high

impedance state.
