MAX3485EESA-HXY

HXY MOSFET · RS-485 / RS-422 ICs · SOP-8

MAX3485EESA-HXY from HXY MOSFET, in a SOP-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, enabled when RE is low and high-impedance when RE is high.
2 RE input Active-low receiver output enable: a logic low enables the receiver and a logic high disables it.
3 DE input Active-high driver output enable: a logic high enables the differential driver outputs and a logic low tri-states them.
4 DI input Driver data input; with DE high, DI high drives A high and B low, and DI low drives A low and B high.
5 GND power_in Ground reference for the device.
6 A bidirectional Non-inverting driver output and non-inverting receiver input, with a receiver sensitivity of ±200mV and a common-mode range of −7V to 12V.
7 B bidirectional Inverting driver output and inverting receiver input, with a receiver sensitivity of ±200mV and a common-mode range of −7V to 12V.
8 VCC power_in Single power supply, specified at 3.3V ±5% (recommended operating range 0 to 3.3 ±5% V).
