AN6780, AN6780S
General Purpose Long Interval Timers
s Overview
The AN6780 and AN6780S are ICs designed for general pur-
pose long interval timers. They consists of an oscillator, fre-
quency 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.
s Features
• High inflow and outflow current : I_O=±15mA max
• Small variation of oscillations
• Long interval timer setting : max 1 week
s Applications
Timers, integrating timers, superlow frequency oscillators
