U2391B Quart- Controlled Pulse Generator Description The monolithic integrated bipolar circuit, U2391B, is designed as a quart- controlled pulse generator. The tristate input enables the selection of different pulse period durations. The internal switch-on monitoring achieves the start up of the IC when the power-on occurs. The output pulse can supply a drive signal upto 150 mA, which is short circuit protected. Features D D D D D D D D Standard quart- fosc = 32.768 kH- Minimum operating voltag
