This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designedto track V
CCA
. V
CCA
accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V
CCB
. V
CCBaccepts any supply voltage from 1.2 V to 3.6 V. The SN74AVC4T245 is optimized to operate with V
CCA
/V
CCB
setat 1.4 V to 3.6 V. It is operational with V
CCA
/V
CCB
as low as 1.2 V. This allows for universal low-voltagebidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVC4T245 is designed for asynchronous communication between two data buses. The logic levels ofthe direction-control (DIR) input and the output-enable ( OE) input activate either the B-port outputs or the A-portoutputs or place both output ports into the high-impedance mode. The device transmits data from the A bus tothe B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs areactivated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW levelapplied to prevent excess I
CC
and I
CCZ
.
The SN74AVC4T245 is designed so that the control pins (1DIR, 2DIR, 1 OE, and 2 OE) are supplied by V
CCA
.
This device is fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.

The V
CC
isolation feature ensures that if either V
CC
input is at GND, then both ports are in the high-impedancestate.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullupresistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
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.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - 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.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
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)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.

express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
