CS48520AM 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: goes high when VID is above VTH+ and low when VID is below VTH-, and goes high-impedance when REB is high or open. |
| 2 | REB | input | Receiver enable, active low, with an internal 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 pull-down; A and B are high-impedance when DE is low or open. |
| 4 | DI | input | Driver data input with an internal pull-up to VCC; when the driver is enabled and DI is open, A is driven high and B low. |
| 5 | GND | power_in | Ground reference for all device voltages. |
| 6 | A | bidirectional | Non-inverting bus input/output; bus voltage limited to -8 V to 13 V (absolute maximum) with ±20 kV HBM and ±6 kV IEC 61000-4-2 contact ESD protection. |
| 7 | B | bidirectional | Inverting bus input/output; bus voltage limited to -8 V to 13 V (absolute maximum) with ±20 kV HBM and ±6 kV IEC 61000-4-2 contact ESD protection. |
| 8 | VCC | power_in | Supply pin, 3.0 V to 5.5 V recommended, with a 100 nF to 220 nF decoupling capacitor to be placed as close to the pin as possible. |
