Hangzhou Ruimeng Tech · Buffers, Drivers, Receivers, Transceivers · SOP-16

MS2576 from Hangzhou Ruimeng Tech, in a SOP-16. 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 1A input RS422 driver 1 data input; datasheet gives VIH min 2 V, VIL max 0.8 V, and a maximum input voltage of 7.0 V.
2 1Y output Driver 1 non-inverting (true) differential output, which goes high-impedance when the driver is disabled.
3 1Z output Driver 1 inverting (complementary) differential output, which goes high-impedance when the driver is disabled.
4 G input Active-high enable input shared by the drivers; the datasheet's function table shows outputs go high-impedance when G is low and GN is high.
5 2Z output Driver 2 inverting (complementary) differential output, which goes high-impedance when the driver is disabled.
6 2Y output Driver 2 non-inverting (true) differential output, which goes high-impedance when the driver is disabled.
7 2A input RS422 driver 2 data input; datasheet gives VIH min 2 V, VIL max 0.8 V, and a maximum input voltage of 7.0 V.
8 GND power_in Ground reference for the device.
9 3A input RS422 driver 3 data input; datasheet gives VIH min 2 V, VIL max 0.8 V, and a maximum input voltage of 7.0 V.
10 3Y output Driver 3 non-inverting (true) differential output, which goes high-impedance when the driver is disabled.
11 3Z output Driver 3 inverting (complementary) differential output, which goes high-impedance when the driver is disabled.
12 GN input Active-low enable input shared by the drivers; the datasheet's function table shows outputs go high-impedance when GN is high and G is low.
13 4Z output Driver 4 inverting (complementary) differential output, which goes high-impedance when the driver is disabled.
14 4Y output Driver 4 non-inverting (true) differential output, which goes high-impedance when the driver is disabled.
15 4A input RS422 driver 4 data input; datasheet gives VIH min 2 V, VIL max 0.8 V, and a maximum input voltage of 7.0 V.
16 VCC power_in Supply pin; recommended supply is 2.7 V to 5.5 V, with an absolute maximum of 7.0 V.
