This 16-bit noninverting bus transceiver uses two
separate configurable power-supply rails. The
SN74AVC16T245 is optimized to operate with

set at 1.4 V to 3.6 V. It is operational

with V
designed to track V
/V
as low as 1.2 V. The A port is
CCA CCB
. V
accepts any supply
CCA CCA
voltage from 1.2 V to 3.6 V. The B port is
designed to track V . V accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal
CCB CCB
low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVC16T245 is designed for asynchronous communication between data buses. The device transmits
data 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 outputs so the buses are
effectively isolated.
The SN74AVC16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V

description/ordering information (continued)
This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.
The V isolation feature ensures that if either V input is at GND, both ports are in the high-impedance state.
CC
CC
To ensure the high-impedance state during power up or power down, OE should be tied to V
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 voltage and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
2. The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current rating is observed.
3. The package thermal impedance is calculated in accordance with JESD 51-7.

power-up considerations
A proper power-up sequence always should be followed to avoid excessive supply current, bus contention,
oscillations, or other anomalies. To guard against such power-up problems, take the following precautions:
1. Connect ground before any supply voltage is applied.
2. Power up V
