f = 20 Hz to 20 kHz.
All outputs are short-circuit proof (static).
The inputs and output (apart from SDA, SCL and OFF) withstand tests of MIL-STD-883 C. It is advisable to
connected series resistors to these pins.

C bus specification. After reset has been activated, transmission may
only be started after a 50
μ
