Inhibit input

The buffering can be inhibited or interrupted with the inhibit input (pin 9). To do this, pin 6 must be connected to the positive pole of the terminal voltage or to the external control voltage and pin 9 must be connected to the corresponding negative pole.

The inhibition of the device also results in the discharging of the internal capacitors. The capacitors cannot be charged as long as the buffer module is in inhibit mode.

For a connection schematic, refer to the illustrations in the chapter Operating diagrams and Connection diagrams.

Signal voltage

Max.

35 Vdc

Voltage between pins 6 and 9

Signal current

Max.

4 mA

Current limited

Inhibit mode

The device does not buffer (or stops buffering) if the voltage between pin 6 and pin 9 is higher than 10 V. The buffering functions again below 6 V.
