ELM381 60 Hz Long Interval Counter Description 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.
Although the circuit has been optimized for a 60Hz input frequency, it is capable of being operated over a very wide range of frequencies.
Of particular interest is the ability to interface directly to very low frequencies with varying waveforms due to the use of a Schmitt trigger input circuit.
The ELM381 provides two outputs – a standard 50% duty cycle divider output, and a momentarily pulsed output.
The pulse output is useful for aud...
