74ABTH16827A
FEATURES
•
Multiple V
CC
and GND pins minimize switching noise
•
Live insertion/extraction permitted
•
3-State output buffers
•
Power-up 3-State
•
74ABTH16827A incorporates bus-hold data inputs which
•
Output capability: +64 mA / –32 mA
•
Latch-up protection exceeds 500 mA per Jedec Std 17
•
ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
eliminate the need for external pull-up resistors to hold unused
inputs
DESCRIPTION
The 74ABT16827A high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16827A 20-bit buffers provide high performance bus
interface buffering for wide data/address paths or buses carrying
parity. They have NOR Output Enables (nOE1, nOE2) for maximum
control flexibility.
Two options are available, 74ABT16827A which does not have the
bus-hold feature and 74ABTH16827A which incorporates the
bus-hold feature.

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 3.4 V.
3. This parameter is valid for any V
CC
between 0 V and 2.1 V with a transition time of up to 10 msec. From V
CC
= 2.1 V to V
CC
= 5 V
±
10% a
transition time of up to 100
µsec
is permitted.
4. Unused pins at V
CC
or GND.
5. This is the bus hold overdrive current required to force the input to the opposite logic state.
