This 16-bit (dual-octal) 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 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, 1 OE, and 2 OE) are supplied by V

CCB

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

input is at GND,

both ports are in the high-impedance state.
