down to about 1.3 V where upon the next trigger is asserted. This is termed

de-assertion for differentiation but in fact it is just the next trigger event.

Typical high-level leakage current is 1.15 mA @ 16.5V DC.

All voltages are with respect to the associated return signal.

Trigger latency is the maximum time from trigger receipt to when the response begins.
