SN7407D buffer driver: open-collector, space-saving.

SN7407D is a Texas Instruments TTL hex buffer driver built for interface control in compact designs. It uses open-collector outputs, allowing the SN7407D to sink current and work with higher-voltage loads when paired with external pull-up resistors. The device accepts standard 5 V TTL inputs and provides clear signal isolation between logic and output stages. Its surface-mount package helps reduce board space while keeping routing simple. Engineers use SN7407D in industrial controls, display drivers, and mixed-voltage systems where output protection matters. Check load limits and layout guidelines before assembly.
