SN65LBC179P

Texas Instruments · RS-485 / RS-422 ICs · PDIP-8

SN65LBC179P from Texas Instruments, in a PDIP-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 5 V supply pin, with a recommended supply range of 4.75 V to 5.25 V and an absolute maximum of 7 V.
2 R output RS-485 receiver logic output, rated for a high-level output current of -8 mA and a low-level output current of 8 mA, with an absolute maximum current of ±10 mA.
3 D input RS-485 driver logic input, requiring a high level of at least 2 V and a low level of at most 0.8 V.
4 GND power_in Ground reference for the device; all voltages are referenced to this pin.
5 Y output Non-inverting RS-485 bus driver output, with output current limited to ±250 mA short-circuit and bus voltage range of -7 V to 12 V.
6 Z output Inverted RS-485 bus driver output, with output current limited to ±250 mA short-circuit and bus voltage range of -7 V to 12 V.
7 B input Inverted RS-485 bus receiver input, with bus voltage range of -7 V to 12 V.
8 A input Non-inverting RS-485 bus receiver input, with bus voltage range of -7 V to 12 V.
