FEATURES
•
Power-up 3-State
•
Multiple V
CC
and GND pins minimize switching noise
•
Provides ideal interface and increases fan-out of MOS
•
•
74ABTH16541 incorporates bus-hold data inputs which eliminate
•
•
ESD protection exceeds 2000 V per MIL STD 883 Method 3015
•
•
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
and 200 V per Machine Model
Two 8-bit bus interfaces
the need for external pull-up resistors to hold unused inputs
Latch-up protection exceeds 500mA per Jedec Std 17
Microprocessors
3-State buffers sink 64mA and source 32mA
DESCRIPTION
The 74ABT16541 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16541 has two octal buffers that are ideal for driving bus
lines. The outputs are all capable of sinking 64mA and sourcing
32mA.
Two options are available, 74ABT16541 which does not have the
bus-hold feature and 74ABTH16541 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 3.4V.
3. This is the bus hold overdrive current required to force the input to the opposite logic state.
