MAX14783EESA+ 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 | RO | output | Receiver output: logic high when A-B is at or above -10mV and logic low when A-B is at or below -200mV, and high impedance when RE is high. |
| 2 | RE | input | Receiver output enable: drive low to enable RO and high to disable the receiver; driving RE high with DE low puts the device into low-power shutdown (under 10µA supply current). |
| 3 | DE | input | Driver output enable: drive high to enable the driver and low to disable it, leaving the driver outputs high impedance; driving RE high with DE low enters low-power shutdown. |
| 4 | DI | input | Driver input: with DE high, a low on DI forces A low and B high, and a high on DI forces A high and B low. |
| 5 | GND | power_in | Ground reference for the device; all voltages are referenced to GND. |
| 6 | A | bidirectional | Noninverting RS-485/RS-422 receiver input and driver output; A and B can also be used as single-ended outputs that swing rail-to-rail. |
| 7 | B | bidirectional | Inverting RS-485/RS-422 receiver input and driver output; A and B can also be used as single-ended outputs that swing rail-to-rail. |
| 8 | VCC | power_in | Positive supply voltage input, 3.0V to 5.5V; bypass VCC with a 0.1µF ceramic capacitor to ground. |
