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.

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.
