AN6780

通用长间隔定时器 General Purpose Long Interval Timers

■Overview

The and AN6780S are ICs designed for general purpose long interval timers. They consists of an oscillator, frequency divider flip-flop 15steps, output circuit, and power circuit. A cycle can be freely set with the external resistor RT and capacity CT of the oscillator.

■Features

•High inflow and outflow current : IO=±15mA max

•Small variation of oscillations

•Long interval timer setting : max 1 week

■Applications

Timers, integrating timers, superlow frequency oscillators
