MAX9141ESA+

Maxim Integrated · Comparators · SOIC-8

MAX9141ESA+ from Maxim Integrated, in a SOIC-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 VCC power_in Positive supply; the operating supply range is 2.7V to 5.5V, and the absolute maximum supply voltage (VCC to GND) is +6V.
2 IN+ input Noninverting comparator input; the input common-mode range extends beyond both supply rails (VCMR -0.2V to VCC + 0.2V), and the input must not exceed VCC + 0.3V relative to GND.
3 IN- input Inverting comparator input; the input common-mode range extends beyond both supply rails (VCMR -0.2V to VCC + 0.2V), and the input must not exceed VCC + 0.3V relative to GND.
4 GND power_in Ground reference for the device.
5 LE input Latch enable: the output is latched when LE is low and the latch is transparent when LE is high; LE accepts levels up to VCC + 0.3V with logic thresholds at VCC/2 ±0.4V.
6 SHDN input Shutdown input: the MAX9141 is active when SHDN is driven high and is in shutdown when driven low, with shutdown enable time of 1µs and disable time of 5µs; connect to VCC for normal operation.
7 OUT tri_state Comparator output, which swings to within 300mV of either supply rail without external pullup and becomes high impedance when the device is in shutdown.
8 N.C. unconnected No connection; not internally connected.
