August 27, 1993 853-1667 10660
FEATURES
•Multiple V
CC
and GND pins minimize
switching noise
•Live insertion/extraction permitted
•3-State output buffers
•Power–up 3-State
•Output capability: +64mA/–32mA
•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
DESCRIPTION
The MB2827 high-performance BiCMOS
device combines low static and dynamic
power dissipation with high speed and high
output drive.
The MB2827 20-bit buffers provide high
performance bus interface buffering for wide
data/address paths or buses carrying parity.
They have NOR Output Enables (nOE
1,
nOE
2) for maximum control flexibility.

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.
