1 Product Description
The TIP606 is an IndustryPack® compatible module designed for avionic test environments. It
provides 16 optically isolated differential inputs for high unipolar input voltage which may exceed the
supply voltage of the module. The inputs can withstand input voltage up to 44V maximum between the
two differential input pins.
Due to the differential inputs of the TIP606, it is even possible to use the module in noisy
environments. The TIP606 provides a high differential input resistance of 112 kohms typically.
The interface circuit will detect a logic 1, if the differential voltage is typically greater than +14.0V and it
will detect a logic 0, if the input voltage is typically lower than +3.5V. The inputs are isolated from the
IP interface via optocouplers. Each input is capable of generating interrupts on rising or falling edges
of the input signal. It is also possible to disable the generation of interrupts and poll the input register
for new data.
All inputs have an electronic debounce circuit. The debounce time is programmable in a range from
900µs up to 230ms in 256 steps of 900µs. The debounce circuit can also be disabled.
