A monolithic power switching flip flop circuit comprising a pair of cross-coupled transistors, each having a "pinch" resistor formed in one common substrate. Each pinch resistor comprises a resistor and a diode connected to each other at one terminal, the second terminal of the resistor being connected to the base of a respective transistor and the other terminal of the diode being connected to the collector of said transistor through the bulk semiconductor material of the common substrate. By suitable external electrical connections, the resistor portion of each pinch resistor is connected in parallel with the diode portion of the other pinch resistor. Thus, each resistor is shunted by a diode and placed in the collector circuit of a respective transistor to form the electrical circuit equivalent of a conventional power switching flip flop utilizing minimum bulk semiconductor material.
