SN75ALS176ADR from Texas Instruments, in a SOIC-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 | R | output | Receiver data output: high when VID ≥ 0.2 V and RE is low, low when VID ≤ −0.2 V and RE is low, and high impedance when RE is high. |
| 2 | RE | input | Receiver enable, active low; driving RE high places the receiver output R in the high-impedance state. |
| 3 | DE | input | Driver enable, active high; when DE is low the driver outputs A and B are high impedance. |
| 4 | D | input | Driver data input; with DE high, D high drives A high and B low, and D low drives A low and B high. |
| 5 | GND | power_in | Local device ground. |
| 6 | A | bidirectional | Driver output or receiver input, complementary to B (noninverting bus terminal); bus terminal voltage must stay within −7 V to 12 V. |
| 7 | B | bidirectional | Driver output or receiver input, complementary to A (inverting bus terminal); bus terminal voltage must stay within −7 V to 12 V. |
| 8 | VCC | power_in | Supply voltage of 4.75 V to 5.25 V (5 V nominal), with an absolute maximum of 7 V. |
