The internal clamping diodes at the contact monitor-
ing inputs, together with the external contact series
resistors RIN, allows the device to withstand tran-
sients at the contact connection. The contact series
resistor RIN limits the input current at the transient.
The dynamic behaviour of the circuit is defined by
the times tdo and tdTS. When the contact becomes
open, the input capacitor CIN must be charged
through the resistor RIN. In this case the total delay
time may also be influenced by the time constant RIN
CIN. The delay time tdTS, when disabling the device
is defined only by the internal circuitry. In both cases,
an external output capacitance less than 50pF is as-
sumed, the internal output capacitances of the
three-state buffers are less than 5pF.
