SN65HVD75EIM

HGSEMI · RS-485 / RS-422 ICs · SOP-8

SN65HVD75EIM from HGSEMI, 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: with RE low, RO is high when A−B is at or above −50 mV and low when A−B is at or below −200 mV, and it is high-impedance when RE is high.
2 RE input Active-low receiver output enable: RO is active when this pin is low and high-impedance when it is high, and RE high together with DE low puts the device into low-power shutdown (hot-plug input).
3 DE input Driver output enable: outputs A and B are active when DE is high and high-impedance when DE is low, and DE high is not a shutdown condition while DE low with RE high enters low-power shutdown (hot-plug input).
4 DI input Driver input: with DE high, a low on DI drives A low and B high, and a high on DI drives A high and B low.
5 GND power_in Ground reference for the device.
6 A bidirectional Non-inverting receiver input and driver output on the bus; the absolute maximum voltage range for A and B is −7 V to +12 V, with ±16 kV IEC 61000-4-2 ESD protection.
7 B bidirectional Inverting receiver input and driver output on the bus; the absolute maximum voltage range for A and B is −7 V to +12 V, with ±16 kV IEC 61000-4-2 ESD protection.
8 VCC power_in Positive supply: 3.15 V ≤ VCC ≤ 3.45 V; place a 0.1 µF capacitor to ground.
