Pin-Tabelle8
| Pin | Signal / Name | Typ | Alternative Funktionen |
|---|---|---|---|
| 1 | OUT A | Digital | Comparator A Output (Open-Collector — requires external pull-up resistor; LOW when INA- > INA+) |
| 2 | INA- | Analog | Inverting Input (-), Comparator A — output goes LOW when INA- > INA+ |
| 3 | INA+ | Analog | Non-Inverting Input (+), Comparator A |
| 4 | V- | Ground | Negative Supply / Ground (0V for single-supply; negative rail for bipolar supply) |
| 5 | INB+ | Analog | Non-Inverting Input (+), Comparator B |
| 6 | INB- | Analog | Inverting Input (-), Comparator B |
| 7 | OUT B | Digital | Comparator B Output (Open-Collector — requires external pull-up resistor; LOW when INB- > INB+) |
| 8 | V+ | Power | Positive Supply Voltage (+2V to +36V single-supply, or ±1V to ±18V dual-supply) |
