| Single Non Inverting Buffer With Open-Collector High-Voltage Output |

Hello, does anyone knows if there is a single non inverting buffer with open drain/collector on chip that will takes 5V as input and with a pull up resistor will have 12V on the output? I found the SN7407 but it has 6 buffers inside the chip. I found many sinlge buffers but not with "High-Voltage Output". Thanks in advance.

Are you constrained by space? |

Yes, space is an issue. |

I'm not aware of of a single-gate part that will handle 12V on the output. If you don't find one, you could combine a single inverting buffer such as the MC74VHC1GT04 with an NPN transistor. You would need a base resistor and the collector resistor to 12V. |
| David Hess:
Do you need current gain? If not, then a single NPN transistor operating in common-base mode with the base biased from the logic supply can operate as a high voltage buffer with an open collector output. A single part like a pre-biased transistor can work this way. Any logic level n-channel MOSFET will also work. |
