ELM337 Description
ELM337 Light Switch .
The ELM337 provides a convenient means to interface standard photocells or light dependent resistors (LDRs) to digital logic circuits.
ELM337 Features
* Low power CMOS design - typically 1mA at 5V
* Operates from 3V to 5.5V
* No external timing elements required
* Low parts count
* Digitally selected delays of up to 10 minutes
* Pulsed or continuous outputs
* Internal line frequency filtering
ELM337 Applications
* need not be limited to those employing photocells, as the Example Applications section shows. The Schmitt trigger input provides a convenient way to interface to virtually any input signal, whether from digital logic or from a slowly varying analog source. The remainder of the ELM337 can simply be t
