ADM3074EARZ

Analog Devices · RS-485/RS-422 ICs · SOIC-8

ADM3074EARZ from Analog Devices, in a SOIC-8. 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 VCC power_in Power supply, 3.3 V ± 10%; bypass VCC to GND with a 0.1 µF capacitor.
2 RO output Receiver output; if (A − B) ≥ −50 mV RO is high, and if (A − B) ≤ −200 mV RO is low.
3 DI input Driver input; with the driver enabled a logic low on DI forces Y low and Z high, and a logic high forces Y high and Z low.
4 GND power_in Ground.
5 Y output Noninverting driver output.
6 Z output Inverting driver output.
7 B input Inverting receiver input B.
8 A input Noninverting receiver input A.

CAD (KiCad official)

  • Symbol: ADM3074EARZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: adm3074earz-etched.step / adm3074earz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adm3074earz.step / adm3074earz.glb are the bare package body.

Provenance
