YD3082EESA

GATEMODE · RS-485 / RS-422 ICs · SOP-8

YD3082EESA from GATEMODE, in a SOP-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: if (A-B) ≥ -50mV, RO is logic high; if (A-B) ≤ -200mV, RO is logic low. VOH ≥ VCC-1.5V at IO=-4mA; VOL ≤ 0.4V at IO=1mA.
2 /RE input Receiver Output Enable (active low). Drive /RE low to enable RO; drive /RE high to place RO in high-impedance. Driving /RE high and DE low enters low-power shutdown mode (ISHDN typ 0.1µA).
3 DE input Driver Output Enable (active high). Drive DE high to enable the A/B driver outputs; when DE is low, driver outputs are high-impedance. Driving /RE high and DE low enters low-power shutdown mode.
4 DI input Driver Input. With DE high, a low on DI forces A (non-inverting) low and B (inverting) high; a high on DI forces A high and B low. VIH=2.0V min, VIL=0.8V max, 100mV typical hysteresis.
5 GND power_in Ground reference for the device.
6 A bidirectional Non-inverting Receiver Input and Non-inverting Driver Output (RS-485/RS-422 differential bus line A). ±15kV HBM ESD protected. Receiver input voltage ±13V, driver output voltage ±13V, receiver input impedance 96kΩ (1/8 unit load).
7 B bidirectional Inverting Receiver Input and Inverting Driver Output (RS-485/RS-422 differential bus line B). ±15kV HBM ESD protected. Receiver input voltage ±13V, driver output voltage ±13V, receiver input impedance 96kΩ (1/8 unit load).
8 VCC power_in Positive supply, VCC = 3.0~5.5V. Bypass VCC to GND with a 0.1µF ceramic capacitor. Absolute maximum +7V.
