DM5406/DM7406 Hex Inverting Buffers with High Voltage Open-Collector Outputs General Description Pull-Up Resistor Equations This device contains six independent buffers each of which performs the logic INVERT function. The open-collector outputs require external pull-up resistors for proper logical operation.
