CS48520M from Chipanalog, in a MSOP-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 data output; per the truth table it is driven high-impedance when REB is high or open, and the bus-fail default drives it high. |
| 2 | REB | input | Receiver enable, active low, with an internal resistor pull-up; the receiver is disabled (RO high-impedance) when REB is high or open. |
| 3 | DE | input | Driver enable, active high, with an internal resistor pull-down; the driver is disabled (A and B high-impedance) when DE is low or open. |
| 4 | DI | input | Driver data input with an internal resistor pull-up to VCC; when the driver is enabled and DI is open, output A goes high. |
| 5 | GND | power_in | Ground reference for all pins; all voltages are referenced to GND. |
| 6 | A | bidirectional | Bus input/output port (non-inverting driver output, receiver input); absolute maximum bus voltage is -8 V to 13 V and recommended bus input voltage is -7 V to 12 V. |
| 7 | B | bidirectional | Bus input/output port (inverting driver output, receiver input); absolute maximum bus voltage is -8 V to 13 V and recommended bus input voltage is -7 V to 12 V. |
| 8 | VCC | power_in | Supply voltage, 3.0 V to 5.5 V recommended with an absolute maximum of 7 V; a 100 nF to 220 nF decoupling capacitor should be placed as close to this pin as possible. |
