ELM381 counter equivalent, 60hz long interval counter.
* Low power CMOS design - typically 1mA at 5V
* Wide supply range
– 3.0 to 5.5 volt operation
* Digitally selectable delays
* Schmitt trig.
section for two typical circuits.
Applications
* Long term (daily or weekly) event timers
* Missing event detect.
The ELM381 is a digitally configurable, multistage counter circuit in a single 8 pin package. When connected to a 60Hz source, four time periods from one hour to one week are possible, as shown in Table 1 below.
