LS7212N PROGRAMMABLE DIGITAL DELAY TIMER

The LS7211N and LS7212N are CMOS integrated circuits for generating digitally programmable delays. The delay is controlled by 8 binary weighted inputs, WB0 - WB7, in conjunction with an applied clock or oscillator frequency. The programmed time delay manifests itself in the Delay Output (OUT) as a .

LS7212N Features

* 8-bit programmable delay from microseconds to days

* On chip oscillator (RC or Crystal) or external clock time base

* Selectable prescaler for real time delay generation based on 50Hz/60Hz time base or 32,768Hz watch crystal

* Four operating modes

* Reset i
