ELM382 Description
The ELM382 is a digitally configurable, multistage counter circuit in a single 8 pin package. When connected to a 50Hz source, four time periods from one hour to one week are possible, as shown in Table 1 below. Although the circuit has been optimized for a 50Hz input frequency, it is capable of being operated over a very wide range of frequencies.
