SN75ALS176P 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 | R | output | Receive data output; it is driven from the differential receiver inputs A and B and goes high impedance when RE is high. |
| 2 | RE | input | Receiver enable, active low; the receiver is enabled when RE is low. |
| 3 | DE | input | Driver enable, active high; the driver outputs A and B are enabled when DE is high and set high impedance when DE is low. |
| 4 | D | input | Driver data input; its logic level sets the differential driver output state when DE is high. |
| 5 | GND | power_in | Local device ground. |
| 6 | A | bidirectional | Driver output or receiver input (complementary to B); it is the non-inverting bus terminal with a common-mode range of -7 V to 12 V. |
| 7 | B | bidirectional | Driver output or receiver input (complementary to A); it is the inverting bus terminal with a common-mode range of -7 V to 12 V. |
| 8 | VCC | power_in | Supply pin; the device requires 4.75 V to 5.25 V (5 V nominal). |
