74ABT863
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
•
Power-up 3-State
•
Live insertion/extraction permitted
•
Inputs are disabled during 3-State mode
DESCRIPTION
The 74ABT863 bus transceiver provides high performance bus
interface buffering for wide data/address paths of buses carrying
parity.
The 74ABT863 9-bit bus transceiver has NOR-ed transmit and
receive output enables for maximum control flexibility.
•
Output capability: +64mA/–32mA
•
Latch-up protection exceeds 500mA per Jedec Std 17
•
ESD protection exceeds 2000V 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.

NOTES:
1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. This parameter is valid for any V
CC
between 0V and 2.1V, with a transition time of up to 10msec. From V
CC
= 2.1V to V
CC
= 5V
±
10%, a
transition time of up to 100µsec is permitted.
