description
The ’ABTH32245 are 36-bit (quad 9-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 four 9-bit transceivers, two18-bit transceivers, or one 36-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) inputs. The output-enable (OE) inputs can be used to disable the device so that
the buses are effectively isolated.
When V
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
CC
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V
the minimum value of the resistor is determined by the current-sinking capability of the driver.
through a pullup resistor;
CC
Active bus-hold circuitry holds unused or floating data inputs at a valid logic level.

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 EIA/JEDEC Std JESD51.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
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)
