Description

The monolithic integrated bipolar circuit, U2391B, is designed as a quartz 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 U2391B IC when the power-on occurs.The output pulse can supply a drive signal upto 150 mA, which is short circuit protected
