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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150
°
C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
4. This parameter is valid for any V
