MAX3483ECSA+T from Maxim Integrated, in a SOP-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 | RO | output | Receiver Output: RO is high if A > B by 200mV and low if A < B by 200mV. |
| 2 | RE | input | Receiver Output Enable: RO is enabled when RE is low and is high impedance when RE is high; RE high with DE low puts the device into low-power shutdown. |
| 3 | DE | input | Driver Output Enable: the driver outputs are enabled by bringing DE high and are high impedance when DE is low. |
| 4 | DI | input | Driver Input: a low on DI forces output Y low and output Z high, and a high on DI forces Y high and Z low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Noninverting Receiver Input and Noninverting Driver Output for the half-duplex MAX3483E. |
| 7 | B | bidirectional | Inverting Receiver Input and Inverting Driver Output for the half-duplex MAX3483E. |
| 8 | VCC | power_in | Positive Supply: 3.0V ≤ VCC ≤ 3.6V; do not operate the device with VCC > 3.6V. |
