**STMicroelectronics** · Comparators · SO-8

TS3702IDT from STMicroelectronics, in a SO-8. 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 | Inverting Input 2 | input | Inverting (negative) input of the second comparator; operates within common-mode input voltage range of 0 to VCC+-1.5V with 1pA typical input bias current. |
| 2 | Output 2 | output | Push-pull CMOS output of the second comparator; requires no external pull-up resistor with VOH minimum 4.3V and VOL maximum 375mV at 5V supply. |
| 3 | Non-inverting Input 2 | input | Non-inverting (positive) input of the second comparator; operates within common-mode input voltage range of 0 to VCC+-1.5V with 1pA typical input bias current. |
| 4 | V- | power_in | Negative supply voltage terminal (ground for single supply operation); device supports single supply 2.7V to 16V or dual supplies ±1.35V to ±8V. |
| 5 | Inverting Input 1 | input | Inverting (negative) input of the first comparator; operates within common-mode input voltage range of 0 to VCC+-1.5V with 1pA typical input bias current. |
| 6 | Non-inverting Input 1 | input | Non-inverting (positive) input of the first comparator; operates within common-mode input voltage range of 0 to VCC+-1.5V with 1pA typical input bias current. |
| 7 | Output 1 | output | Push-pull CMOS output of the first comparator; requires no external pull-up resistor with VOH minimum 4.3V and VOL maximum 375mV at 5V supply. |
| 8 | VCC+ | power_in | Positive supply voltage terminal; device supports single supply 2.7V to 16V or dual supplies ±1.35V to ±8V with typical quiescent current of 9μA per comparator. |
