ISO7220ADR

Texas Instruments · Digital Isolators · SOIC-8

ISO7220ADR from Texas Instruments, 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 VCC1 power_in Supply voltage for input channels, 3.0V to 5.5V operating range
2 INA input TTL-compatible input for channel A, 5V-tolerant with 150mV hysteresis
3 INB input TTL-compatible input for channel B, 5V-tolerant with 150mV hysteresis
4 GND1 power_in Ground reference for input supply VCC1
5 GND2 power_in Ground reference for output supply VCC2
6 OUTB output 4mA CMOS output for channel B, galvanically isolated from input side
7 OUTA output 4mA CMOS output for channel A, galvanically isolated from input side
8 VCC2 power_in Supply voltage for output channels, 3.0V to 5.5V operating range

CAD (KiCad official)

  • Symbol: ISO7220ADR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: iso7220adr-etched.step / iso7220adr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); iso7220adr.step / iso7220adr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (39 pp, sha256 64d2f4d0c91c1ed3, retrieved 2026-09-24, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.2, primary claude-haiku-4-5-20251001 (text), consensus claude-sonnet-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
