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 (R
T
)
and capacity (C
T
) of the oscillator.
