U2391B Datasheet (TEMIC Semiconductors) - Quartz Controlled Pulse Generator

U2391B, Quartz Controlled Pulse Generator

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 IC when the power-on occurs.

The output pulse can supply
