MAX941ESA+T

Analog Devices Inc Maxim Integrated · Comparators · SO-8

MAX941ESA+T from Analog Devices Inc Maxim Integrated, in a SO-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 V+ power_in Positive supply, specified from 2.7V to 5.5V, with V+ to GND not to exceed 6.5V.
2 IN+ input Comparator noninverting input, with a common-mode range of -0.2V to V+ + 0.2V and inputs that tolerate 0.3V beyond either rail without damage.
3 IN- input Comparator inverting input, with a common-mode range of -0.2V to V+ + 0.2V and inputs that tolerate 0.3V beyond either rail without damage.
4 SHDN input Shutdown control: the comparator is active when driven high and enters shutdown (supply current below 60µA, output high impedance) when driven low, so it should be connected to V+ for normal operation.
5 LATCH input Output latch control: the output is stored when LATCH is driven low and the latch is transparent when LATCH is high, with the datasheet giving logic thresholds of V+/2 ± 0.4V.
6 GND power_in Ground reference for the supply and comparator, to which V+ is referenced and must not exceed 6.5V.
7 OUT output Comparator output that swings to within 0.4V of either supply rail without external pullup and is CMOS/TTL compatible, with the output going high impedance in shutdown.
8 N.C. unconnected No connection; the pin is not internally connected.
