the High-Impedance State
This 32-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is
designed to track V
CCA
. V
CCA
accepts any supply voltage from 1.4 V to 3.6 V. The B port is designed to track
V
CCB
. V
CCB
accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional
translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVCBH324245 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 is used to disable the outputs, so the buses effectively
are isolated.
The SN74AVCBH324245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V
CCB
.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullup or
pulldown resistors with the bus-hold circuitry is not recommended.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CCB
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
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. If either V
CC
input is at GND,
both ports are in the high-impedance state.

32-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
SCES550B FEBRUARY 2004 REVISED JUNE 2005
The DOCTM circuitry is implemented, which, during the transition, initially lowers the output impedance to
effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1 shows typical
V
OL
vs I
OL
and V
OH
vs I
OH
curves to illustrate the output impedance and drive capability of the circuit. At the
beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that is equivalent to a
high-drive standard-output device. For more information, refer to the TI application reports, AVC Logic Family
Technology and Applications, literature number SCEA006, and Dynamic Output Control (DOCTM) Circuitry
Technology and Applications, literature number SCEA009.

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)
