– 1000-V Charged-Device Model (C101)  
DESCRIPTION  
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 SN74AVCB164245 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 SN74AVCB164245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCB  
.
To ensure the high-impedance state during power up or power down, OE should be tied to VCCB 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,  
both ports are in the high-impedance state.
