GS8748-SR

Gainsil · Comparators · SOP-8

GS8748-SR from Gainsil, in a SOP-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	OUTA	output	Comparator A output; rail-to-rail, CMOS/TTL-compatible.
2	INA-	input	Comparator A inverting input; rail-to-rail, common-mode range VSS-0.1V to VDD+0.1V.
3	INA+	input	Comparator A non-inverting input; rail-to-rail, common-mode range VSS-0.1V to VDD+0.1V.
4	VSS	power_in	Negative supply or ground; supply VDD to VSS is 2.7V to 5.5V (absolute max 7.5V).
5	INB+	input	Comparator B non-inverting input; rail-to-rail, common-mode range VSS-0.1V to VDD+0.1V.
6	INB-	input	Comparator B inverting input; rail-to-rail, common-mode range VSS-0.1V to VDD+0.1V.
7	OUTB	output	Comparator B output; rail-to-rail, CMOS/TTL-compatible.
8	VDD	power_in	Positive supply; 2.7V to 5.5V operation (absolute max 7.5V), bypass with 0.1uF ceramic capacitor close to the pin.

CAD (KiCad official)

Symbol: GS8748-SR
Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOP-8 (KiCad packages3D, STEP)
3D model files: gs8748-sr-etched.step / gs8748-sr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8748-sr.step / gs8748-sr.glb are the bare package body.
