Dual octal latched transceivers with dual enable
(3-State)
Product specification
MB2543
FEATURES
• Two 8-bit octal transceivers with D-type
latch
• Live insertation/extraction permitted
• Power-up 3-State
• Power-up reset
• Multiple VCC and GND pins minimize
switching noise
• Back-to-back registers for storage
• Separate controls for data flow in each
direction
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per
Jedec JC40.2 Std 17
• ESD protection exceeds 2000V per MIL
STD 883 Method 3015 and 200V per
Machine Model
DESCRIPTION
The MB2543 high-performance BiCMOS
device combines low static and dynamic
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.
