Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. Leave floating or tie to a nearby quiet net; do not use as a routing via. |
| 2 | NC | unconnected | No internal connection. Leave floating or tie to a nearby quiet net; do not use as a routing via. |
| 3 | GND1 | power_in | Ground return for comparator 1. Separate from GND2 so channel 1's inputs and open-collector output can be referenced to an isolated ground. |
| 4 | -IN1 | input | Inverting input of comparator 1. Analog input; input bias current 500 nA typ (1 µA max over temp), differential input voltage rated ±5 V, common-mode range typically ±13 V at VCC=±15 V. |
| 5 | +IN1 | input | Non-inverting input of comparator 1. Analog input; input bias current 500 nA typ (1 µA max over temp), differential input voltage rated ±5 V, common-mode range typically ±13 V at VCC=±15 V. |
| 6 | VCC- | power_in | Negative supply rail. Tie to 0 V for single-supply operation from +5 V, or down to -15 V for dual-supply operation. Absolute max -25 V. |
| 7 | OUT2 | output | Comparator 2 output. Open-collector NPN referenced to GND2; requires an external pull-up to a rail up to +36 V above VCC-. Sink capability up to 25 mA (VOL ≤ 1.5 V at 25 mA, ≤ 0.4 V at 3.2 mA); TTL-compatible. |
| 8 | GND2 | power_in | Ground return for comparator 2. Separate from GND1 so channel 2's inputs and open-collector output can be referenced to an isolated ground. |
| 9 | +IN2 | input | Non-inverting input of comparator 2. Analog input; input bias current 500 nA typ (1 µA max over temp), differential input voltage rated ±5 V, common-mode range typically ±13 V at VCC=±15 V. |
| 10 | -IN2 | input | Inverting input of comparator 2. Analog input; input bias current 500 nA typ (1 µA max over temp), differential input voltage rated ±5 V, common-mode range typically ±13 V at VCC=±15 V. |
| 11 | VCC+ | power_in | Positive supply rail. Range +5 V (single supply, with VCC- = 0 V) up to +15 V (dual supply). Absolute max +18 V. Positive supply current 8 mA typ / 11.5 mA max at ±15 V. |
| 12 | OUT1 | output | Comparator 1 output. Open-collector NPN referenced to GND1; requires an external pull-up to a rail up to +36 V above VCC-. Sink capability up to 25 mA (VOL ≤ 1.5 V at 25 mA, ≤ 0.4 V at 3.2 mA); TTL-compatible. |
| 13 | NC | unconnected | No internal connection. Leave floating or tie to a nearby quiet net; do not use as a routing via. |
| 14 | NC | unconnected | No internal connection. Leave floating or tie to a nearby quiet net; do not use as a routing via. |
