MS2576

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.
