SIT75176BDR from SIT, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver Output. When /RE is low and if A - B≥200mV, RO will be high; if A - B≤-200mV, RO will be low. |
| 2 | /RE | input | Receiver Output Enable. Drive /RE low to enable RO; RO is high impedance when /RE is high. Drive /RE high and DE low to enter low-power shutdown mode. |
| 3 | DE | input | Driver Output Enable. Drive DE high to enable driver outputs. These outputs are high impedance when DE is low. Drive /RE high and DE low to enter low-power shutdown mode. |
| 4 | DI | input | Driver Input. With DE high, a low on DI forces non-inverting output low and inverting output high. Similarly, a high on DI forces non-inverting output high and inverting output low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting Receiver Input and non-inverting Driver Output. |
| 7 | B | bidirectional | Inverting Receiver Input and Inverting Driver Output. |
| 8 | VCC | power_in | Positive Supply. |
