ELM337 switch equivalent, light switch.
* Low power CMOS design - typically 1mA at 5V
* Operates from 3V to 5.5V
* No external timing elements required
* Low parts count
* Digitally selected.
need not be limited to those employing photocells, as the Example Applications section shows. The Schmitt trigger input .
The ELM337 provides a convenient means to interface standard photocells or light dependent resistors (LDRs) to digital logic circuits. It provides an input comparator with hysteresis, line frequency filtering, digital delays, and high current output .
