SN65LBC170DB

Texas Instruments · RS-485 / RS-422 ICs · SSOP-16-208mil

SN65LBC170DB from Texas Instruments, in a SSOP-16-208mil. 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	1D	bidirectional	Channel 1 data pin: driver input when 1DIR is high and receiver output when 1DIR is low, with VIH of 2 V to VCC and VIL of 0 V to 0.8 V.
2	1DIR	input	Channel 1 direction input: high enables the driver, low enables the receiver, with VIH of 2 V to VCC and VIL of 0 V to 0.8 V.
3	NC	unconnected	No internal connection.
4	GND	power_in	Ground terminal, network ground reference for all voltages.
5	2D	bidirectional	Channel 2 data pin: driver input when 2DIR is high and receiver output when 2DIR is low, with VIH of 2 V to VCC and VIL of 0 V to 0.8 V.
6	2DIR	input	Channel 2 direction input: high enables the driver, low enables the receiver, with VIH of 2 V to VCC and VIL of 0 V to 0.8 V.
7	3D	bidirectional	Channel 3 data pin: driver input when 3DIR is high and receiver output when 3DIR is low, with VIH of 2 V to VCC and VIL of 0 V to 0.8 V.
8	3DIR	input	Channel 3 direction input: high enables the driver, low enables the receiver, with VIH of 2 V to VCC and VIL of 0 V to 0.8 V.
9	3A	bidirectional	Channel 3 differential bus I/O (non-inverting side), common-mode range -7 V to 12 V.
10	3B	bidirectional	Channel 3 differential bus I/O (inverting side), common-mode range -7 V to 12 V.
11	2A	bidirectional	Channel 2 differential bus I/O (non-inverting side), common-mode range -7 V to 12 V.
12	2B	bidirectional	Channel 2 differential bus I/O (inverting side), common-mode range -7 V to 12 V.
13	VCC	power_in	Single 5 V supply, recommended 4.75 V to 5.25 V (absolute maximum -0.3 V to 6 V).
14	NC	unconnected	No internal connection.
15	1A	bidirectional	Channel 1 differential bus I/O (non-inverting side), common-mode range -7 V to 12 V.
16	1B	bidirectional	Channel 1 differential bus I/O (inverting side), common-mode range -7 V to 12 V.
