Panasonic AN6780S, AN6780 Datasheet

■ Overview

The AN6780 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
