INTERFACING TTL OR CMOS LOGIC TO 50–VOLT, 1000–OHMS RELAY
FOR TELEPHONY APPLICATIONS
In order to interface positive logic to negative–powered electromechanical relays, a change in voltage level and polarity plus
electrical isolation are required. The H11Gx can provide this interface and eliminate the external amplifiers and voltage divider
networks previously required. The circuit below shows a typical approach for the interface.
