Download the LS7212N datasheet PDF.
This datasheet also covers the LS7211N variant, as both devices belong to the same programmable digital delay timer family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
Key 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.
