Description:

The UCY7406 is a hex inverter buffer IC with open-collector outputs, designed for interfacing TTL logic levels with higher-voltage or higher-current loads. Manufactured by Unitra CEMI, it’s part of the 7400-series logic family and is functionally equivalent to the SN7406. Each of its six inverters can sink significant current, making it ideal for driving relays, lamps, or other inductive loads. Its open-collector configuration allows for flexible voltage interfacing and wired-AND logic applications.
