Transient Pulse 
To reduce the possibility of inadvertent operation of devices 
connected to transistor outputs, adhere to the following guidelines:
•Either ensure that any programmable device connected to the 
transistor output is programmed toignore all output signals until 
after the transient pulse has ended,
•Add an external resistor in parallel to the load to increase the 
on-state load current. The duration of the transient pulse is 
reduced when the on-state load current is increased. 
The duration of the transient pulse is proportional to the load 
impedance. This is illustrated in the following graph.
