DM7406N Hex Inverter With Open-Collector Outputs

DM7406N is used when you need both inversion and an open-collector interface on the same device. It’s common in legacy control panels for driving optocouplers, relay driver stages, small lamps, and wired logic lines that rely on pull-ups. DM7406N includes six independent inverting buffers with open-collector outputs and operates from a 4.75 V to 5.25 V supply for 5V TTL compatibility. The open-collector output lets you select the pull-up voltage to match the receiving circuit, while keeping the logic input referenced to the local 5V rail. Use appropriately sized pullup resistors, add transient suppression for inductive loads, and keep high-current loops tight to limit noise. Request a quote for DM7406N.
