Description
The ELM627 is a complete circuit for detecting break signals on RS232 lines, in an 8 pin package. This is useful for remotely resetting circuits through a serial link. For convenience, this circuit also generates an output pulse on power-up.

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

Applications
• Remote resetting of RS232 devices
• Edge triggered one-shot circuits
• Digitally controlled sequencing schemes
• Watchdog type signal monitors
