The MC74LCX16244 is a high performance, non-inverting 16-bit buffer operating from a 2.3 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 TTLlevel bus oriented transceiver applications.

The 4.5ns maximum propagation delays support high performance applications. Current drive capability is 24mA at the outputs. The Output Enable (OEn)bar inputs, when HIGH, disable the outputs by placing them ina HIGH Z condition.

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)bar input for each nibble. When OEnbar is LOW, the outputs are on. When OEnbar is HIGH, the outputs are in the high impedance state.
