3OE
The 74ABT162244 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.
GND
4Y2
The 74ABT162244 is designed with 30Ω series resistance in both
the upper and lower output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers
and bus receivers/transmitters.

SA00013
The 74ABT162244 is the same as the 74ABT16244-1. The part
number has been changed to reflect industry standards.
Two options are available, 74ABT162244 which does not have the
bus hold feature and the 74ABTH162244 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.
