MAX13433EIDRG

HANSCHIP semiconductor · RS-485/RS-422 ICs · SOP-14

MAX13433EIDRG from HANSCHIP semiconductor, in a SOP-14. 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 VL power_in Input logic level supply, bypassed with a 0.1µF capacitor from VL to GND placed as close as possible to the pin, with VL operating from 1.62V to VCC.
2 RO output Receiver output that is high when V(A)-V(B) is greater than or equal to -50mV and low when V(A)-V(B) is less than or equal to -200mV while the receiver is enabled.
3 DE input Driver output enable; a high level enables the driver and a low level disables it so its outputs go to high impedance.
4 RE input Receiver output enable; RO is active when RE is low and the receiver is disabled when RE is high.
5 DI input Driver input; DI low forces the non-inverting output low and the inverting output high, and DI high forces the non-inverting output high and the inverting output low.
6 GND power_in Ground reference for the device.
7 NC unconnected Not connected.
8 GND power_in Ground reference for the device.
9 Y bidirectional Driver non-inverting output and receiver non-inverting input.
10 Z bidirectional Driver inverting output and receiver inverting input.
11 B bidirectional Bus terminal B, the inverting input of the receiver, with the receiver threshold between -50mV and -200mV on A-B.
12 A bidirectional Bus terminal A, the non-inverting input of the receiver, with the receiver threshold between -50mV and -200mV on A-B.
13 NC unconnected Not connected.
14 VCC power_in Positive supply, bypassed with a 0.1µF capacitor from VCC to GND, with a recommended supply range of 3 to 5.5V.
