Overview

ELM626 RS232 Break Detector Description 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 transmitted null character, @, at various baud rates.
This provides a convenient means for the remote triggering of this circuit by simply shifting to a lower baud rate and sending a null byte.
Two complementary high current outputs are provided by the ELM626, so that further buffering is not usually required.
The output signal can be selected to be either a c...
