AN6783S

ICs for Timer AN6783S IC for long interval timer s Overview The AN6783S is an IC designed for a long interval timer. It is oscillated by using the external resistor and capacitor, and the oscillation frequency divided by a 15stage F.F. is provided as the output. It is frequency divider type, so that a long interval timer can be constructed by using a capacitor with small capacitance. 0.4±0.25 0.6±0.3 Unit : mm 1 2 1.27 3 4 8 7 6 5 5.0±0.3 1.5±0.2 0.15 0.65 Oscillation frequency dispersion of IC itself is small (±5 %) Oscillation frequency can be checked by 1/2 fOSC monitor terminal Wide operating supply voltage range (3.2 V to 18 V) Small consumption current (3 mA typ.) 0.1±0.1 0.3 4.2±0.3 6.5±0.3 s Features SOP008-P-0225A s Applications Timer s Block Diagram Mon.
