LS7211 PROGRAMMABLE DIGITAL DELAY TIMER

The LS7211/LS7212 are monolithic 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.

LS7211 Features

* 8-bit programmable delay from nanoseconds 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 32.768KHz watch crystal

* Four operating modes

* Reset i
