DM7407N Hex Buffer With Open-Collector Outputs

DM7407N is a solid choice when a logic output needs to control something beyond another gate input. It’s often used to drive indicator lamps, relay interface stages, optocouplers, and wired-OR lines where a pull-up defines the high state. DM7407N provides six non-inverting buffer channels with open-collector outputs and operates from a 4.75 V to 5.25 V supply, keeping the input side aligned with 5V TTL logic. Because the output is open collector, you choose the pull-up voltage and resistor value based on the load and required sink current. Add flyback protection for inductive loads and keep return paths short to reduce ground bounce. Request a quote for DM7407N.
