Abstract
A semiconductor switching circuit utilizes a relatively low breakdown voltage transistor for switching between a higher and a lower voltage by switching between a first conducting state of said transistor which is a "turned-on" state and a second state which is a "breakdown" state. The switching circuit is especially useful for the operation of display devices.
Claims9
A semiconductor switching circuit for switching between a higher and a lower voltage comprising:
- a first transistor having a breakdown voltage substantially equal to the difference between said higher and said lower voltages and less than said higher voltage, said transistor including a control electrode and first and second current carrying electrodes;
- and
- control means connected to said control electrode for alternately switching said first transistor between a first current carrying state when said transistor is turned on and a breakdown state when said transistor is off.
