S-8081B Datasheet Cr Timer

Manufacturer: Seiko Instruments Inc

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.

Key Features

  • Wide power supply operating range : 4.5 to 16.5 V.
  • Low current consumption : 200 µA max. (C = 200 kΩ, R = 0.0047 µF, open output ).
  • 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 performed n.
