ELM626 RS232 Break Detector

The ELM626 is a complete circuit for detecting break signals on RS232 lines, in an 8 pin package. The circuit is similar to the ELM627 except that an output pulse is not generated on power-up. The threshold for break signal detection is user selectable, allowing the circuit to respond to a transmitt.

ELM626 Features

* Low power CMOS design - typically 1mA at 5V

* No external timing elements required

* Complementary outputs

* Digitally controlled threshold timing

* Selectable output duration

* High current drive outputs - up to 25 mA Connection Diagram PDIP and SO
