MAX1487ESA-HXY

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

MAX1487ESA-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, which is logic high when A-B is at least +0.2V or the inputs are open, logic low when A-B is at most -0.2V, and high impedance when RE is high.
2 RE input Active-low receiver enable input; drive low to enable the receiver output, high to place RO in high impedance (VIL max 0.8V, VIH min 2.0V).
3 DE input Driver enable input; high enables the driver outputs A and B, low places them in high impedance (VIL max 0.8V, VIH min 2.0V).
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 (VIL max 0.8V, VIH min 2.0V).
5 GND power_in Ground.
6 A bidirectional Non-inverting RS-485/RS-422 receiver input and driver output, rated -8V to +12.5V with ±15kV HBM ESD protection.
7 B bidirectional Inverting RS-485/RS-422 receiver input and driver output, rated -8V to +12.5V with ±15kV HBM ESD protection.
8 VCC power_in Positive supply input, operated from a single +5V ±5% supply with a 0.1µF bypass capacitor and an absolute maximum of 12V.
