SN65LBC175ADR

Texas Instruments · RS-485 / RS-422 ICs · SOIC-16

SN65LBC175ADR from Texas Instruments, in a SOIC-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 1B input Channel 1 inverting differential bus input, with bus common-mode range of -7 V to 12 V.
2 1A input Channel 1 non-inverting differential bus input, with bus common-mode range of -7 V to 12 V.
3 1Y output Channel 1 receiver output, which goes high impedance when enable 1,2EN is low or open.
4 1,2EN input Active-high enable for channels 1 and 2, with VIH of 2 V minimum and VIL of 0.8 V maximum; tie to 3,4EN to enable all four receivers together.
5 2Y output Channel 2 receiver output, which goes high impedance when enable 1,2EN is low or open.
6 2A input Channel 2 non-inverting differential bus input, with bus common-mode range of -7 V to 12 V.
7 2B input Channel 2 inverting differential bus input, with bus common-mode range of -7 V to 12 V.
8 GND power_in Device ground, to which all voltages are referenced.
9 3B input Channel 3 inverting differential bus input, with bus common-mode range of -7 V to 12 V.
10 3A input Channel 3 non-inverting differential bus input, with bus common-mode range of -7 V to 12 V.
11 3Y output Channel 3 receiver output, which goes high impedance when enable 3,4EN is low or open.
12 3,4EN input Active-high enable for channels 3 and 4, with VIH of 2 V minimum and VIL of 0.8 V maximum; tie to 1,2EN to enable all four receivers together.
13 4Y output Channel 4 receiver output, which goes high impedance when enable 3,4EN is low or open.
14 4A input Channel 4 non-inverting differential bus input, with bus common-mode range of -7 V to 12 V.
15 4B input Channel 4 inverting differential bus input, with bus common-mode range of -7 V to 12 V.
16 VCC power_in Device supply, specified at 4.75 V to 5.25 V (5 V nominal).
