Product specification
Dual octal bus transceiver/registers (3-State)
MB2646
The MB2646 dual transceiver/register
consists of two sets of bus transceiver
FEATURES
• Latch-up protection exceeds 500mA per
Jedec JC40.2 Std 17
• Independent registers for A and B buses
circuits with 3-State outputs, D-type flip-flops,
and control circuitry arranged for multiplexed
transmission of data directly from the input
bus or from the internal registers. Data on the
A or B bus will be clocked into the registers
as the appropriate clock pin goes High.
Output Enable (nOE) and Direction (nDIR)
pins are provided to control the transceiver
function. In the transceiver mode, data
present at the high impedance port may be
stored in either the A or B register or both.
• ESD protection exceeds 2000V per MIL
STD 883 Method 3015 and 200V per
Machine Model
• Multiple V and GND pins minimize
CC
switching noise
• Live insertion/extraction permitted
• Power-up 3-State
DESCRIPTION
• Power-up reset
The MB2646 high-performance BiCMOS
device combines low static and dynamic
power dissipation with high speed and high
output drive.
• Multiplexed real-time and stored data
• Outputs sink 64mA and source 32mA

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 between 0V and 2.1V, with a transition time of up to 10msec. From V = 2.1V to V = 5V ± 10% a
