Product specification
Dual octal latched transceivers with dual enable
(3-State)
FEATURES
• Two 8-bit octal transceivers with D-type
MB2543
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per
latch
• Live insertation/extraction permitted
• Power-up 3-State
• Power-up reset
• Multiple VCC and GND pins minimize
power dissipation with high speed and high
output drive.
The MB2543 dual octal registered transceiver
contains two sets of D-type latches for
temporary storage of data flowing in either
direction. Separate Latch Enable (nLEAB,
nLEBA) and Output Enable (nOEAB,
nOEBA) inputs are provided for each
register to permit independent control of data
transfer in either direction. The outputs are
guaranteed to sink 64mA.
Jedec JC40.2 Std 17
• ESD protection exceeds 2000V per MIL
STD 883 Method 3015 and 200V per
Machine Model
switching noise
DESCRIPTION
• Back-to-back registers for storage
• Separate controls for data flow in each
The MB2543 high-performance BiCMOS
device combines low static and dynamic
direction

Dual octal latched transceivers with dual enable
(3-State)
A subsequent Low-to-High transition of the
nLEAB signal puts the A data into the latches
where it is stored and the B outputs no longer
change with the A inputs. With EAB and
nOEAB both Low, the 3-State B output
FUNCTIONAL DESCRIPTION
The MB2543 contains two sets of eight
D-type latches, with separate control pins for
each set. Using data flow from A to B as an
example, when the A-to-B Enable (nEAB)
input and the A-to-B Latch Enable (nLEAB)
input are Low the A-to-B path is transparent.
MB2543
buffers are active and display the data
present at the outputs of the A latches.
Control of data flow from B to A is similar, but
using the nEBA, nLEBA, and nOEBA inputs.

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.

NOTES:
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 VCC between 0V and 2.1V, with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5V ± 10% a
transition time of up to 100µsec is permitted.
