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 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
V
CCA
.
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
CCA
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,
then both ports are in the high-impedance state.
