August 23, 1993

853–1656 10584

FEATURES

• Two 8-bit octal transceivers with D-type

latch

• Live insertation/extraction permitted

• Power-up 3-State

• Power-up reset

• Multiple V

CC 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.
