MAX3030EEUE+T

Maxim Integrated · RS-485/RS-422 ICs · TSSOP-16

MAX3030EEUE+T from Maxim Integrated, in a TSSOP-16. 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	DI1	input	Transmitter 1 input: when transmitter 1 is enabled, a low forces DO1+ low and DO1- high, and a high forces DO1+ high and DO1- low.
2	DO1+	output	Noninverting RS-422 output of transmitter 1.
3	DO1-	output	Inverting RS-422 output of transmitter 1.
4	EN	input	Active-high transmitter enable for all four transmitters: drive HIGH to enable, LOW to three-state the outputs; input is hot-swap protected.
5	DO2-	output	Inverting RS-422 output of transmitter 2.
6	DO2+	output	Noninverting RS-422 output of transmitter 2.
7	DI2	input	Transmitter 2 input: when transmitter 2 is enabled, a low forces DO2+ low and DO2- high, and a high forces DO2+ high and DO2- low.
8	GND	power_in	Ground reference for the device.
9	DI3	input	Transmitter 3 input: when transmitter 3 is enabled, a low forces DO3+ low and DO3- high, and a high forces DO3+ high and DO3- low.
10	DO3+	output	Noninverting RS-422 output of transmitter 3.
11	DO3-	output	Inverting RS-422 output of transmitter 3.
12	EN	input	Active-low transmitter enable for all four transmitters: drive LOW to enable, HIGH to three-state the outputs; input is hot-swap protected.
13	DO4-	output	Inverting RS-422 output of transmitter 4.
14	DO4+	output	Noninverting RS-422 output of transmitter 4.
15	DI4	input	Transmitter 4 input: when transmitter 4 is enabled, a low forces DO4+ low and DO4- high, and a high forces DO4+ high and DO4- low.
16	VCC	power_in	Positive supply, +3V to +3.6V; bypass VCC to GND with a 0.1µF capacitor.
