MAX14783EESA+

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

MAX14783EESA+ 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 RO output Receiver output: logic high when A-B is at or above -10mV and logic low when A-B is at or below -200mV, and high impedance when RE is high.
2 RE input Receiver output enable: drive low to enable RO and high to disable the receiver; driving RE high with DE low puts the device into low-power shutdown (under 10µA supply current).
3 DE input Driver output enable: drive high to enable the driver and low to disable it, leaving the driver outputs high impedance; driving RE high with DE low enters low-power shutdown.
4 DI input Driver input: with DE high, a low on DI forces A low and B high, and a high on DI forces A high and B low.
5 GND power_in Ground reference for the device; all voltages are referenced to GND.
6 A bidirectional Noninverting RS-485/RS-422 receiver input and driver output; A and B can also be used as single-ended outputs that swing rail-to-rail.
7 B bidirectional Inverting RS-485/RS-422 receiver input and driver output; A and B can also be used as single-ended outputs that swing rail-to-rail.
8 VCC power_in Positive supply voltage input, 3.0V to 5.5V; bypass VCC with a 0.1µF ceramic capacitor to ground.
