LOW_STANDBY_DRAIN

Positive 12-V pulse at input A triggers SOS Q1 and turns on transistor switch Q3, Positive pulse at input B gates SCS Q2 on and turns off Q3. Current drain is essentially zero (typically 3 μA). Circuit was designed to supply up to 7 mA of switched current from 12-VDC supply.-D. B. Heckrnan, Bistable Switch with Zero Standby Drain, EDN|EEE Magazine, Oct. 1, 1971, p 42.
