DESCRIPTION:
technology. The ALVCH162245 is designed for asynchronous com-
munication between data buses. The control-function implementation
minimizes external timing requirements.
transceiver. It allows data transmission 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 device so that the buses are effectively isolated.
ture of the “A” port which will significantly reduce line noise when used
with light loads. This driver has been designed to drive ±12mA at the
designated threshold levels. The “B” port has a ±24mA driver.
state whenever the input bus goes to a high impedance. This prevents
floating inputs and eliminates the need for pull-up/down resistors.
This 16-bit bus transceiver is built using advanced dual metal CMOS
This device can be used as two 8-bit transceivers or one 16-bit
The ALVCH162245 has series resistors in the device out-put struc-
The ALVCH162245 has “bus-hold” which retains the inputs’ last
