MS2583

Hangzhou Ruimeng Tech · RS-485/RS-422 ICs · SOP-8

MS2583 from Hangzhou Ruimeng Tech, 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 VCC power_in Power supply pin; the datasheet gives a recommended supply range of +2.5 V to +5.5 V and an absolute maximum of +6 V.
2 RO output Receiver output; the absolute maximum output voltage is -0.5 V to +6 V.
3 DI input Driver input; logic high requires at least 2 V and logic low at most 0.8 V.
4 GND power_in Ground reference pin for the device.
5 Y output Bus driver output Y; the absolute maximum driver output voltage is -0.5 V to +6 V.
6 Z output Bus driver output Z; the absolute maximum driver output voltage is -0.5 V to +6 V.
7 B input Bus receiver input B; the bus input voltage range is -7 V to +10 V.
8 A input Bus receiver input A; the bus input voltage range is -7 V to +10 V.
