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 VI 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.
