description/ordering information
The 'ABT162245 devices are 16-bit noninverting
3-state transceivers designed for synchronous
two-way communication between data buses.
The control-function implementation minimizes
external timing requirements.
These devices can be used as two 8-bit
transceivers or one 16-bit transceiver. They allow
data transmission from the A bus to the B bus or
from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable
(OE) input can be used to disable the device so that the buses effectively are isolated.
The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 25-
series resistors
to reduce overshoot and undershoot.
These devices are fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the
outputs, preventing damaging current backflow through the devices when they are powered down.

description/ordering information (continued)
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Stresses beyond those listed under "absolute maximum ratings" 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.
NOTES:
1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.

* On products compliant to MIL-PRF-38535, this parameter does not apply.
All typical values are at VCC = 5 V.
This limit applies only to the SN74ABT162245.
The parameters IOZH and IOZL include the input leakage current.
Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
# This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
