LS7211N Datasheet PDF (PROGRAMMABLE DIGITAL DELAY TIMER)

LS7211N - 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.
