ISO722DR

Texas Instruments · Digital Isolators · SOIC-8

ISO722DR 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 Power supply VCC1, operating range 3V to 5.5V; redundant connection available on pin 3.
2 IN input TTL logic input (VIH 2V to 5.5V, VIL 0V to 0.8V); 5V tolerant when supplied from 3.3V.
3 VCC1 power_in Redundant VCC1 power supply connection; optional, can be left open if pin 1 is connected.
4 GND1 power_in Ground return for VCC1 side of isolation barrier.
5 GND2 power_in Ground return for VCC2 side of isolation barrier.
6 OUT output Logic output with 4mA CMOS stage and 12ns typical propagation delay; subject to EN gating.
7 EN input Active-low output enable; drives OUT to high-impedance when EN is high; enabled when EN is low or left open.
8 VCC2 power_in Power supply VCC2, operating range 3V to 5.5V.

CAD (KiCad official)

  • Symbol: ISO722DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: iso722dr-etched.step / iso722dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); iso722dr.step / iso722dr.glb are the bare package body.
