SEMICONDUCTOR TECHNICAL DATA

The MC74LCX16501 is a high performance, non–inverting 18–bit

universal bus transceiver operating from a 2.7 to 3.6V supply. This part is

not byte controlled; it is “18–bit” controlled. High impedance TTL

compatible inputs significantly reduce current loading to input drivers

while TTL compatible outputs offer improved switching noise

performance. A V specification of 5.5V allows MC74LCX16501 inputs to

be safely driven from 5V devices. The MC74LCX16501 is suitable for

memory address driving and all TTL level bus oriented transceiver

applications.

Data flow in each direction is controlled by Output Enable (OEAB,

OEBA), Latch Enable (LEAB, LEBA) and Clock inputs (CAB, CBA). When

LEAB is HIGH, the A–to–B dataflow is transparent. When LEAB is LOW,

and CAB is held at LOW or HIGH, the data A is latched; on the

LOW–to–HIGH transition of CAB the A–data is stored in the

latch/flip–flop. The outputs are active when OEAB is HIGH. When OEAB

is LOW the B–outputs are in 3–state. Similarly, the LEBA, OEBA and CBA

control the B–to–A dataflow. Please note that the output enables are

complementary; OEAB is active HIGH, OEBA is active LOW.
