MAX3485CSA-JSM

JSMSEMI · RS-485/RS-422 ICs · SOP-8

MAX3485CSA-JSM from JSMSEMI, 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, enabled when RE is low and high impedance when RE is high.
2 RE input Receiver output enable, active low; a logic low enables the receiver and a logic high disables it (input high ≥2.0V, low ≤0.6V).
3 DE input Driver output enable, active high; a logic high enables the driver outputs and a logic low places them in high impedance (input high ≥2.0V, low ≤0.6V).
4 DI input Driver input; logic level on DI sets the differential driver outputs A and B when the driver is enabled (input high ≥2.0V, low ≤0.6V).
5 GND power_in Ground.
6 A bidirectional Non-inverting driver output and non-inverting receiver input, with a −7V to 12V receiver common-mode range.
7 B bidirectional Inverting driver output and inverting receiver input, with a −7V to 12V receiver common-mode range.
8 VCC power_in Power supply, 3.3V ±5% recommended operating range (absolute maximum 6.0V).
