DESCRIPTION
The MB2052 high-performance BiCMOS
device combines low static and dynamic
power dissipation with high speed and high
output drive.
The MB2052 is a dual octal registered
transceiver. Two 8-bit registers store data
flowing in both directions between two
bidirectional buses. Data applied to the inputs
is entered and stored on the rising edge of
the Clock (nCPXX) provided that the Clock
Enable (nCEXX) is Low. The data is then
present at the 3-State output buffers, but is
only accessible when the Output Enable
(nOEXX) is Low. Data flow from A inputs to B
outputs is the same as for B inputs to A
outputs.
