Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT2 | output | Output pin of comparator 2; for the TLV181x push-pull output it sinks and sources current and must never be connected to another output. |
| 2 | OUT1 | output | Output pin of comparator 1; for the TLV181x push-pull output it sinks and sources current and must never be connected to another output. |
| 3 | V+ | power_in | Positive supply pin; the full supply voltage range VS = (V+) - (V-) is 2.4 V to 40 V. |
| 4 | IN1- | input | Negative (inverting) input of comparator 1; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 5 | IN1+ | input | Positive (non-inverting) input of comparator 1; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 6 | IN2- | input | Negative (inverting) input of comparator 2; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 7 | IN2+ | input | Positive (non-inverting) input of comparator 2; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 8 | IN3- | input | Negative (inverting) input of comparator 3; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 9 | IN3+ | input | Positive (non-inverting) input of comparator 3; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 10 | IN4- | input | Negative (inverting) input of comparator 4; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 11 | IN4+ | input | Positive (non-inverting) input of comparator 4; the input voltage range extends from 200 mV below V- to 200 mV above V+. |
| 12 | V- | power_in | Negative supply pin; the minimum supply voltage is 2.4 V across (V+) - (V-). |
| 13 | OUT4 | output | Output pin of comparator 4; for the TLV181x push-pull output it sinks and sources current and must never be connected to another output. |
| 14 | OUT3 | output | Output pin of comparator 3; for the TLV181x push-pull output it sinks and sources current and must never be connected to another output. |
