MAX483ESA+T

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

MAX483ESA+T from Analog Devices Inc Maxim Integrated, in a SOIC-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: if A > B by 200mV, RO will be high; if A < B by 200mV, RO will be low.
2 RE input Receiver Output Enable: RO is enabled when RE is low, and RO is high impedance when RE is high.
3 DE input Driver Output Enable: the driver outputs (Y and Z, pins A and B when DE is high) are enabled by bringing DE high and are high impedance when DE is low.
4 DI input Driver Input: a low on DI forces output Y low and output Z high, and a high on DI forces output Y high and output Z low.
5 GND power_in Ground.
6 A bidirectional Noninverting Receiver Input and Noninverting Driver Output.
7 B bidirectional Inverting Receiver Input and Inverting Driver Output.
8 VCC power_in Positive Supply: 4.75V ≤ VCC ≤ 5.25V.
