CS48505M

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

CS48505M 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: RO goes high when VID = VA - VB exceeds VTH+ and low when VID falls below VTH-, and it is high-impedance when REB is high or open.
2 REB input Receiver enable, active low with an internal pull-up: the receiver is enabled when REB is low and 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, and the driver is disabled when DE is open.
4 DI input Driver data input with an internal pull-up to VCC: when the driver is enabled, DI high drives A high and B low, DI low reverses the outputs, and an open DI drives A high and B low.
5 GND power_in Ground reference for all voltages on the device.
6 A bidirectional Bus input/output port (non-inverting RS-485 line); absolute maximum bus voltage is -8 V to 13 V and recommended bus input voltage is -7 V to 12 V, both referenced to GND.
7 B bidirectional Bus input/output port (inverting RS-485 line); absolute maximum bus voltage is -8 V to 13 V and recommended bus input voltage is -7 V to 12 V, both referenced to GND.
8 VCC power_in Supply voltage, 3.0 V to 5.5 V referenced to GND (absolute maximum 7 V), with a 100 nF to 220 nF decoupling capacitor recommended as close to the pin as possible.
