MAX3488ESA+T

Analog Devices Inc Maxim Integrated · RS-485 / RS-422 ICs · SO-8

MAX3488ESA+T from Analog Devices Inc Maxim Integrated, in a SO-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 VCC power_in Positive supply, 3.0V ≤ VCC ≤ 3.6V.
2 RO output Receiver Output: RO is high if A > B by 200mV and low if A < B by 200mV.
3 DI input Driver Input: a low on DI forces output Y low and output Z high, and a high on DI forces Y high and Z low.
4 GND power_in Ground.
5 Y output Noninverting driver output.
6 Z output Inverting driver output.
7 B input Inverting receiver input (receiver-only on the MAX3488; the driver output is on Z).
8 A input Noninverting receiver input (receiver-only on the MAX3488; the driver output is on Y).
