MAX3094ECSE+T

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

MAX3094ECSE+T from Maxim Integrated, in a SO-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 output YA goes high when A+ exceeds A- by 200mV and low when A+ is below A- by 200mV.
2 A+ input Noninverting receiver A input; the receiver output YA goes high when A+ exceeds A- by 200mV and low when A+ is below A- by 200mV.
3 YA output Receiver A output, enabled when ENAC is high, logic high if A+ exceeds A- by 200mV or if the inputs float, logic low if A+ is below A- by 200mV, and high impedance when ENAC is low.
4 ENAC input Active-high enable for receiver outputs A and C; a logic high enables receivers A and C, and a logic low (together with ENBD low) puts the device in shutdown.
5 YC output Receiver C output with the same functionality as YA, enabled when ENAC is high and high impedance when ENAC is low.
6 C+ input Noninverting receiver C input, with a common-mode range of -7V to +12V per the receiver specifications.
7 C- input Inverting receiver C input, with a common-mode range of -7V to +12V per the receiver specifications.
8 GND power_in Device ground; all voltages are referenced to this pin.
9 D- input Inverting receiver D input, with a common-mode range of -7V to +12V per the receiver specifications.
10 D+ input Noninverting receiver D input, with a common-mode range of -7V to +12V per the receiver specifications.
11 YD output Receiver D output, enabled when ENBD is high, logic high if D+ exceeds D- by 200mV or if the inputs float, logic low if D+ is below D- by 200mV, and high impedance when ENBD is low.
12 ENBD input Active-high enable for receiver outputs B and D; a logic high enables receivers B and D, and a logic low (together with ENAC low) puts the device in shutdown.
13 YB output Receiver B output with the same functionality as YD, enabled when ENBD is high and high impedance when ENBD is low.
14 B+ input Noninverting receiver B input, with a common-mode range of -7V to +12V per the receiver specifications.
15 B- input Inverting receiver B input, with a common-mode range of -7V to +12V per the receiver specifications.
16 VCC power_in Positive supply; the MAX3094E operates from +3.0V to +3.6V (+3.3V typical).
