If Either VCC Input Is at GND, Both Ports Are in  
the High-Impedance State  
– 1000-V Charged-Device Model (C101)  
Overvoltage-Tolerant Inputs/Outputs Allow  
Mixed-Voltage-Mode Data Communications  
DESCRIPTION/ORDERING INFORMATION  
This 16-bit (dual-octal) noninverting bus transceiver uses two separate configurable power-supply rails. The  
A port is designed to track VCCA. VCCA accepts any supply voltage from 1.4 V to 3.6 V. The B port is designed to  
track VCCB. VCCB 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 SN74AVCAH164245 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 SN74AVCAH164245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA  
.
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 VCCA 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 Ioff. The Ioff circuitry disables the outputs,  
preventing damaging current backflow through the device when it is powered down. If either VCC input is at GND,  
then both ports are in the high-impedance state.

(4) The bus-hold circuit can sink at least the minimum low sustaining current at VIL max. IBHL should be measured after lowering VIN to GND  
and then raising it to VIL max.  
(5) The bus-hold circuit can source at least the minimum high sustaining current at VIH min. IBHH should be measured after raising VIN to  
VCC and then lowering it to VIH min.  
(6) An external driver must source at least IBHLO to switch this node from low to high.  
(7) An external driver must sink at least IBHHO to switch this node from high to low.  
(8) For I/O ports, the parameter IOZ includes the input leakage current.

SCES396A–JULY 2002–REVISED JUNE 2005  
Output Description  
The DOC™ 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 VOL vs  
IOL and VOH vs IOH 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 (DOC™) Circuitry Technology and  
Applications, literature number SCEA009.

(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
