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. |
