MAX3093EESE+T

Analog Devices Inc Maxim Integrated · RS-485 / RS-422 ICs · SOIC-16

MAX3093EESE+T from Analog Devices Inc Maxim Integrated, in a SOIC-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 A- input Inverting receiver A input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
2 A+ input Noninverting receiver A input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
3 YA output Receiver A output, logic high when A+ exceeds A- by 200mV, logic low when A+ is below A- by 200mV, and high impedance when ENAC is low.
4 ENAC input Active-high enable for receivers A and C; a logic high enables them, and the device enters shutdown when ENAC and ENBD are both low.
5 YC output Receiver C output, with the same functionality as YA: logic high when C+ exceeds C- by 200mV, logic low when C+ is below C- by 200mV, and high impedance when ENAC is low.
6 C+ input Noninverting receiver C input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
7 C- input Inverting receiver C input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
8 GND power_in Device ground, to which all voltages in the datasheet are referenced.
9 D- input Inverting receiver D input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
10 D+ input Noninverting receiver D input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
11 YD output Receiver D output, logic high when D+ exceeds D- by 200mV, logic low when D+ is below D- by 200mV, and high impedance when ENBD is low.
12 ENBD input Active-high enable for receivers B and D; a logic high enables them, and the device enters shutdown when ENAC and ENBD are both low.
13 YB output Receiver B output, with the same functionality as YD: logic high when B+ exceeds B- by 200mV, logic low when B+ is below B- by 200mV, and high impedance when ENBD is low.
14 B+ input Noninverting receiver B input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
15 B- input Inverting receiver B input; the receiver inputs are rated for ±25V absolute maximum and present a 48kΩ (1/4 unit load) input resistance.
16 VCC power_in Positive supply; the MAX3093E is specified for +5V ±5% operation (VCC = 4.75V to 5.25V).
