3PEAK · Comparators · SOIC-8

TP1942-SR from 3PEAK, in a SOIC-8. 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 OUTA output Comparator A push-pull output. CMOS/TTL compatible, rail-to-rail swing (VOH = VDD-0.3V @ 1mA, VOL = VSS+0.3V @ 1mA). Short-circuit current typ 25 mA; absolute max output current +/-45 mA.
2 -INA input Comparator A inverting input. Rail-to-rail input range extends 200 mV below VSS and above VDD. Input bias current 6 pA typ; input voltage limited to V- - 0.3V to V+ + 0.3V.
3 +INA input Comparator A non-inverting input. Rail-to-rail input range extends 200 mV below VSS and above VDD. Input bias current 6 pA typ.
4 V- power_in Negative supply / ground reference (VSS). Total supply V+ - V- must not exceed 6.0V absolute max; typical single-supply operation 1.8V to 5.5V with V- tied to GND.
5 +INB input Comparator B non-inverting input. Rail-to-rail input range extends 200 mV below VSS and above VDD. Input bias current 6 pA typ.
6 -INB input Comparator B inverting input. Rail-to-rail input range extends 200 mV below VSS and above VDD. Input bias current 6 pA typ.
7 OUTB output Comparator B push-pull output. CMOS/TTL compatible, rail-to-rail swing (VOH = VDD-0.3V @ 1mA, VOL = VSS+0.3V @ 1mA). Short-circuit current typ 25 mA.
8 V+ power_in Positive supply (VDD). Single-supply range 1.8V to 5.5V; absolute max V+ - V- = 6.0V. Quiescent current 46 uA typ per comparator (92 uA total for dual).
