SN75C1168DBR

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

SN75C1168DBR 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 1B input Inverting input of Channel 1 differential receiver.
2 1A input Non-inverting input of Channel 1 differential receiver.
3 1R tri_state Single-ended receiver output for Channel 1, high impedance when disabled.
4 1DE input Driver active-high enable input for Channel 1; LOW disables driver outputs to high impedance.
5 2R tri_state Single-ended receiver output for Channel 2, high impedance when disabled.
6 2A input Non-inverting input of Channel 1 differential receiver.
7 2B input Inverting input of Channel 2 differential receiver.
8 GND power_in Device ground, voltage reference.
9 2D input Single-ended driver input for Channel 2.
10 2Y tri_state Non-inverting output of Channel 2 differential driver, high impedance when 2DE is LOW.
11 2Z tri_state Inverting output of Channel 2 differential driver, high impedance when 2DE is LOW.
12 2DE input Driver active-high enable input for Channel 2; LOW disables driver outputs to high impedance.
13 1Z tri_state Inverting output of Channel 1 differential driver, high impedance when 1DE is LOW.
14 1Y tri_state Non-inverting output of Channel 1 differential driver, high impedance when 1DE is LOW.
15 1D input Single-ended driver input for Channel 1.
16 VCC power_in Positive supply voltage; connect 4.5V to 5.5V with respect to GND per page 4.
