LS7212N - PROGRAMMABLE DIGITAL DELAY TIMER

Download the LS7212N datasheet PDF (LS7211N included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for programmable digital delay timer.

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.

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 input for delay abort.
Low quiescent and operating current.
Direct relay drive.
+3V to +18V operation (VDD - VSS).
LS7211N, LS7212N (DIP); LS7211N-S, LS7212N-S (SOIC.
