DESCRIPTION:
This 16-bit bus transceiver is built using advanced dual metal CMOS
technology. The ALVCHR162245 device is designed for asynchronous
communication between data buses. The control-function implementation
minimizes external timing requirements.
This device can be used as two 8-bit transceivers or one 16-bit
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.
The ALVCHR162245 has series resistors in the device output structure
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 ALVCHR162245 has âbus-holdâ which retains the inputsâ last state
whenever the input bus goes to a high impedance. This prevents floating
inputs and eliminates the need for pull-up/down resistors.
