LM2901YDT from STMicroelectronics, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT2 | output | Open-collector output of comparator 2. Requires an external pull-up resistor to a positive supply (typ. 3 kΩ to 100 kΩ). Sinks up to 16 mA when active low; V_OL ≤ 250 mV at 4 mA sink. |
| 2 | OUT1 | output | Open-collector output of comparator 1. Requires an external pull-up resistor to a positive supply. Sinks up to 16 mA when active low. |
| 3 | VCC+ | power_in | Positive supply voltage. Single-supply operation from 2 V to 36 V (LM2901Y max 36 V), or split-supply ±1 V to ±18 V. Quiescent current typ. 0.8 mA (all four comparators, no load). |
| 4 | IN1- | input | Inverting input of comparator 1. Input common-mode range extends from V- (or GND in single-supply) up to V+ - 1.5 V. Input bias current typ. 25 nA. |
| 5 | IN1+ | input | Non-inverting input of comparator 1. Input common-mode range extends from V- (or GND) up to V+ - 1.5 V. Input offset voltage typ. ±2 mV (max ±7 mV). |
| 6 | IN2- | input | Inverting input of comparator 2. Input common-mode range extends from V- (or GND) up to V+ - 1.5 V. |
| 7 | IN2+ | input | Non-inverting input of comparator 2. Input common-mode range extends from V- (or GND) up to V+ - 1.5 V. |
| 8 | IN3+ | input | Non-inverting input of comparator 3. Input common-mode range extends from V- (or GND) up to V+ - 1.5 V. |
| 9 | IN3- | input | Inverting input of comparator 3. Input common-mode range extends from V- (or GND) up to V+ - 1.5 V. |
| 10 | IN4+ | input | Non-inverting input of comparator 4. Input common-mode range extends from V- (or GND) up to V+ - 1.5 V. |
| 11 | IN4- | input | Inverting input of comparator 4. Input common-mode range extends from V- (or GND) up to V+ - 1.5 V. |
| 12 | OUT4 | output | Open-collector output of comparator 4. Requires an external pull-up resistor to a positive supply. Sinks up to 16 mA when active low. |
| 13 | OUT3 | output | Open-collector output of comparator 3. Requires an external pull-up resistor to a positive supply. Sinks up to 16 mA when active low. |
| 14 | GND | power_in | Ground / negative supply (V-). Connect to 0 V for single-supply operation, or to the negative rail for split-supply operation (down to -18 V relative to V+). |
