GS8743-CR from Gainsil, in a SC-70-5. 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 | OUT | output | Comparator output. CMOS/TTL-compatible push-pull output; rail-to-rail swing (VOH = VDD - 0.166V, VOL = 132mV typical at IO = 4mA). Short-circuit source/sink currents ~42.6/43.7mA typical. |
| 2 | VSS | power_in | Negative supply / ground. Referenced to GND in single-supply operation (2.7V to 5.5V); may be tied to a negative rail for dual ±1.35V to ±2.75V supply operation. |
| 3 | IN+ | input | Non-inverting comparator input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V). Input bias current 6pA typical, input offset voltage 5mV max. |
| 4 | IN- | input | Inverting comparator input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V). Input bias current 6pA typical, 3mV internal hysteresis referenced between inputs. |
| 5 | VDD | power_in | Positive supply. Single-supply +2.7V to +5.5V (absolute max +7.5V). Bypass with 0.1uF ceramic capacitor placed close to this pin. |
