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.
- 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.
