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. |
