CS48520M

Chipanalog · RS-485 / RS-422 ICs · MSOP-8

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.
