S-8081B Overview
DISCONTINUED PRODUCT Rev.1.1 CR TIMER S-8081B The S-8081B is a CMOS CR timer developed for appliances and industrial equipment use. It consists of a CR oscillator, a 20-stage divider, a power-on clear circuit, a trigger input chattering rejection circuit, an internal voltage regulator, a level shift circuit, and an output driver. It can be used as a high-precision, long-time monostable timer.
S-8081B Key Features
- Wide power supply operating range : 4.5 to 16.5 V
- Low current consumption : 200 µA max.(C = 200 kΩ
- Time can be set by external CR
- Excellent oscillation stability because of built-in voltage regulator
- Power-on clear circuit is integrated
- Both trigger I/O inverting operation and set/reset operation can be
