SN7407N buffer driver: open-collector, durable.

SN7407N is a Texas Instruments TTL hex buffer driver designed for signal isolation and current sinking. Each channel uses an open-collector output, which allows SN7407N to interface with higher-voltage loads such as relays, lamps, or LEDs. The device accepts standard 5 V TTL inputs and provides reliable switching without internal pull-up resistors. Its DIP package supports easy placement and servicing on through-hole boards. Engineers use SN7407N in control panels, industrial interfaces, and mixed-voltage systems where protection and flexibility matter. Review output load limits and add external pull-ups as required.
