MAX9142EKA+T

Analog Devices Inc Maxim Integrated · Comparators · SOT-23-8

MAX9142EKA+T from Analog Devices Inc Maxim Integrated, in a SOT-23-8. 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 swings to within 300mV of either supply rail without external pullup, and it tolerates a continuous short-circuit fault to either rail.
2 INA- input Comparator A inverting input; the input range extends beyond both supply rails (VCMR -0.2V to VCC + 0.2V) and IN+/IN- must stay within -0.3V to VCC + 0.3V to GND.
3 INA+ input Comparator A noninverting input; the input range extends beyond both supply rails (VCMR -0.2V to VCC + 0.2V) and IN+/IN- must stay within -0.3V to VCC + 0.3V to GND.
4 GND power_in Ground reference for the device; the supply limit is VCC to GND of 6V maximum.
5 INB+ input Comparator B noninverting input; the input range extends beyond both supply rails (VCMR -0.2V to VCC + 0.2V) and IN+/IN- must stay within -0.3V to VCC + 0.3V to GND.
6 INB- input Comparator B inverting input; the input range extends beyond both supply rails (VCMR -0.2V to VCC + 0.2V) and IN+/IN- must stay within -0.3V to VCC + 0.3V to GND.
7 OUTB output Comparator B output swings to within 300mV of either supply rail without external pullup, and it tolerates a continuous short-circuit fault to either rail.
8 VCC power_in Positive supply; the operating supply range is 2.7V to 5.5V with an absolute maximum of 6V.
