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

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.
