When high logic is fed to the input both the transistors begin to conduct providing a path to ground for the external load that the output is connected.

Thic Daasheet consists of a eight NPN Darlington connected transistors with common Clamp diodes for switching the loads connected to the output. The following two tabs change content below. Or if you don’t have an account with us yet, then click here to register.


When no base voltage is applied that when is no signal is given to the input pins of the ICthere will be no base current and transistor remains in off state.
