TYPICAL APPLICATION CIRCUIT

The UCA9617 is 5V tolerant, so it does not require any additional circuitry to translate between 0.8V to 5.5V bus

voltages and 2.2V to 5.5V bus voltages. A typical application is shown in Figure 7. In this example, the system master

is running on a 3.3V I

ca n be placed on either bus.

When port A of the UCA9617 is pulled LOW by a driver on the I

When port B of the UCA9617 falls, first a CMOS hysteresis type input detects the falling edge and causes the internal

driver on port A to turn on and pull the port A pin down to ground.
