LM339ADBR from Texas Instruments, in a SSOP-14-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | tri_state | Open-drain output of comparator 2; output low voltage is 0.11 to 0.55 V at sink current 4 mA when IN2- exceeds IN2+ above input offset voltage. |
| 2 | OUT2 | tri_state | Open-drain output of comparator 1; output low voltage is 0.11 to 0.55 V at sink current 4 mA when IN1- exceeds IN1+ above input offset voltage. |
| 3 | VCC | power_in | Positive supply voltage; recommended operating range 2 to 36 V for LM339A. |
| 4 | IN2- | input | Negative (inverting) input of comparator 1; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 5 | IN2+ | input | Positive (non-inverting) input of comparator 1; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 6 | IN1- | input | Negative (inverting) input of comparator 2; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 7 | IN1+ | input | Positive (non-inverting) input of comparator 2; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 8 | IN3- | input | Negative (inverting) input of comparator 3; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 9 | IN3+ | input | Positive (non-inverting) input of comparator 3; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 10 | IN4- | input | Negative (inverting) input of comparator 4; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 11 | IN4+ | input | Positive (non-inverting) input of comparator 4; common-mode input voltage range (V-) to (V+) - 2.0 V over operating temperature. |
| 12 | GND | power_in | Negative supply voltage (ground); return path for supply current and reference potential. |
| 13 | OUT4 | tri_state | Open-drain output of comparator 4; output low voltage is 0.11 to 0.55 V at sink current 4 mA when IN4- exceeds IN4+ above input offset voltage. |
| 14 | OUT3 | tri_state | Open-drain output of comparator 3; output low voltage is 0.11 to 0.55 V at sink current 4 mA when IN3- exceeds IN3+ above input offset voltage. |
