DESCRIPTION:
This 16-bit bus transceiver is built using advanced CMOS technology. The
AUCR16245 is designed specifically for asynchronous communications be-
tween data buses. The control function implementation minimizes external timing
requirements.
This device can be used as one 16-bit transceiver or two 8-bit transceivers.
It allows data transmission from A bus to B bus or from B bus to A bus, depending
on the logic level at the direction-control (DIR) input. The output-enable (OE)
input can be used to disable the device so that the buses are effectively isolated.
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.
The AUCR16245 has series resistors in the device output structure which will
reduce line noise when used with light loads. This driver has been designed
with a ±4.5mA output driver at the designated threshold levels.
To ensure the high-impedance state during power up or power down, OE
should be tied to VDD through a pull-up resistor; the minimum value of the resistor
is determined by the current-sinking capability of the driver.
