August 27, 1993 853-1715 10661

DESCRIPTION

The MB2861 bus transceiver provides high
performance bus interface buffering for wide
data/address paths of buses carrying parity.

The MB2861 10-bit bus transceiver has
NOR-ed transmit and receive output enables
for maximum control flexibility.

FEATURES

•Provides high performance bus interface

buffering for wide data/address paths or
buses carrying parity

•Buffered control inputs for light loading, or

increased fan-in as required with MOS
microprocessors

•Output capability: +64mA/-32mA

•Power-up 3-State

•Live insertion/extraction permitted

•Latch-up protection exceeds 500mA per

Jedec JC40.2 Std 17

•ESD protection exceeds 2000 V per MIL

STD 883 Method 3015 and 200 V per
Machine Model
