MAX3041EUE+

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

MAX3041EUE+ 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 T1IN input Transmitter 1 driver input that controls the Y1/Z1 outputs; the datasheet gives VIH of 2.0V minimum and VIL of 0.8V maximum for T_IN.
2 Y1 output Noninverting transmitter 1 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
3 Z1 output Inverting transmitter 1 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
4 EN12 input Active-high transmitter enable for transmitters 1 and 2; driving it low disables those transmitters, and the part enters low-power shutdown only when both EN12 and EN34 are low.
5 Z2 output Inverting transmitter 2 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
6 Y2 output Noninverting transmitter 2 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
7 T2IN input Transmitter 2 driver input that controls the Y2/Z2 outputs; the datasheet gives VIH of 2.0V minimum and VIL of 0.8V maximum for T_IN.
8 GND power_in Ground reference for the device; all device voltages are referenced to GND.
9 T3IN input Transmitter 3 driver input that controls the Y3/Z3 outputs; the datasheet gives VIH of 2.0V minimum and VIL of 0.8V maximum for T_IN.
10 Y3 output Noninverting transmitter 3 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
11 Z3 output Inverting transmitter 3 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
12 EN34 input Active-high transmitter enable for transmitters 3 and 4; driving it low disables those transmitters, and the part enters low-power shutdown only when both EN12 and EN34 are low.
13 Z4 output Inverting transmitter 4 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
14 Y4 output Noninverting transmitter 4 output, high impedance when the transmitter is disabled, with ±10kV Human Body Model ESD protection.
15 T4IN input Transmitter 4 driver input that controls the Y4/Z4 outputs; the datasheet gives VIH of 2.0V minimum and VIL of 0.8V maximum for T_IN.
16 VCC power_in Positive 5V supply (5V ±5% in the electrical characteristics); bypass with a 0.1µF capacitor to GND.
