Description

The ELM381 is a digitally configurable, multi stage 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.

Features

? 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
