MAX487ESA-HXY

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

MAX487ESA-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 (labelled R/RO); when RE is low and A-B ≥ +0.2V RO is high, and when A-B ≤ -0.2V RO is low, with a high-impedance output when the receiver is disabled.
2 RE input Receiver output enable, active low; RE low enables RO, RE high makes RO high-impedance, and RE high with DE low enters low-power shutdown.
3 DE input Driver output enable, active high; DE high enables the A and B driver outputs, DE low makes them high-impedance, and DE low with RE high enters shutdown.
4 DI input Driver input (labelled D/DI); with DE high, a low on DI forces A low and B high, and a high on DI forces A high and B low, with a rated input voltage of -0.3V to 6V.
5 GND power_in Ground.
6 A bidirectional Noninverting receiver input and noninverting driver output, with a bus voltage range of -7V to +12V and ±16kV ESD protection.
7 B bidirectional Inverting receiver input and inverting driver output, with a bus voltage range of -7V to +12V and ±16kV ESD protection.
8 VCC power_in Positive supply of +5V (5V ±0.25V in the DC characteristics), absolute maximum 6V, bypassed with a 0.1µF capacitor.
