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 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, 1OE, and 2OE) 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
CC
input is at GND,
both ports are in the high-impedance state.
