The TS120 is a multi-function telecom switch integrated circuit that combines a 350 V normally open (1-Form-A) relay with a Darlington transistor optocoupler in a single package. The TS120 is a ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

This module considers basic circuit topologies. Circuits such as long - tailed pairs, Darlington transistors and current mirrors are described as a precursor to exploring the internal design of a ...

This module brings together the underlying physical principles of BJT, JFET and MOSFET devices to show how structural decisions in device design affect performance as a circuit element. Basic circuit ...
