5.7 Open Drain Output, Dual Versions

The LMC7221 is a comparator similar to the LMC7211-N, but with an open drain output which allows the output voltage to be different (higher or lower) than the supply voltage. The open drain output is like the open collector output of a logic gate. This makes the LMC7221 very useful for mixed voltage systems. Many systems have different voltages for the analog and microprocessor sections. Please see the LMC7221 data sheet for details.

The performance of the LMC7211-N is available in dual devices. Please see the LMC6762 data sheet for details on a dual push-pull output device. For a dual device with open drain outputs, please see the LMC6772 data sheet.
