Texas Instruments · Comparators · TSSOP-8
LM393PWR from Texas Instruments, in a TSSOP-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 | 1OUT | output | Open-collector output of comparator 1 compatible with TTL/MOS/CMOS logic; maximum output current 20mA. |
| 2 | 1IN- | input | Negative input of comparator 1; input voltage range 0 to (VCC - 2.0V). |
| 3 | 1IN+ | input | Positive input of comparator 1; input voltage range 0 to (VCC - 2.0V). |
| 4 | GND | power_in | Ground; connection to negative power supply rail. |
| 5 | 2IN+ | input | Positive input of comparator 2; input voltage range 0 to (VCC - 2.0V). |
| 6 | 2IN- | input | Negative input of comparator 2; input voltage range 0 to (VCC - 2.0V). |
| 7 | 2OUT | output | Open-collector output of comparator 2 compatible with TTL/MOS/CMOS logic; maximum output current 20mA. |
| 8 | VCC | power_in | Positive power supply; operating voltage range 2 to 30V for LM393. |
