ELM381 Datasheet 60hz Long Interval Counter

Manufacturer: ELM Electronics

Overview: ELM381 60 Hz Long Interval Counter.

Datasheet Details

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.

Low power CMOS design - typically 1mA at 5V.
Wide supply range.
3.0 to 5.5 volt operation.
Digitally selectable delays.
Schmitt trigger circuitry on the clock input.
Completely static operation.
Long term accuracy with line frequency clock.
High current drive outputs.
up to 25 mA.
Reset input provided with a pullup resistor Connection Diagram PDIP and SOIC (top view) VDD 1 D1 2 D0 3 reset 4 8 VSS 7 Out.
