65HVD72EIM

HGSEMI · RS-485 / RS-422 ICs · SOIC-8

65HVD72EIM from HGSEMI, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO output Receiver output. When /RE is low, RO drives high if (A-B) ≥ -50mV and low if (A-B) ≤ -200mV. High-impedance when receiver is disabled (/RE high) or in shutdown.
2 /RE input Receiver output enable, active low. RO is valid when /RE is low; RO is high-Z when /RE is high. If /RE=high and DE=low simultaneously, the device enters low-power shutdown mode. Hot-swap input structure.
3 DE input Driver output enable, active high. Driver outputs (A, B) are enabled when DE is high; outputs are high-impedance when DE is low. If DE=low and /RE=high, the device enters low-power shutdown mode. Hot-swap input structure.
4 DI input Driver data input. When DE is high, a logic-low on DI drives A low and B high; a logic-high on DI drives A high and B low. VIH = 2V min, VIL = 0.8V max.
5 GND power_in Ground reference for the device.
6 A bidirectional Non-inverting receiver input and non-inverting driver output for the RS-485/RS-422 differential bus. Withstands -7V to +12V bus common-mode range. 96 kΩ input impedance (1/8 unit load).
7 B bidirectional Inverting receiver input and inverting driver output for the RS-485/RS-422 differential bus. Withstands -7V to +12V bus common-mode range. 96 kΩ input impedance (1/8 unit load).
8 VCC power_in Positive supply, 3.15V ≤ VCC ≤ 3.45V (nominal 3.3V). Bypass with a 0.1 µF capacitor to GND close to the pin.
