CC
and GND pins minimize switching noise
Power-up 3-State
3-State buffers
Output capability: +64 mA/32mA
Live insertion/extraction permitted
Latch-up protection exceeds 500mA per JEDEC Std 17
ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
74ABTH16244A incorporates bus hold data inputs which eliminate
the need for external pull up resistors to hold unused inputs
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ABT16244A high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16244A device is a 16-bit buffer that is ideal for driving
bus lines. The device features four Output Enables (1OE, 2OE,
3OE, 4OE), each controlling four of the 3-State outputs.
Two options are available, 74ABT16244A which does not have the
bus hold feature and 74ABTH16244A 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 data sheet limit may vary among suppliers.
4. This is the bus hold overdrive current required to force the input to the opposite logic state.
