Texas Instruments · Digital Isolators · SSOP-16-150mil

ISO7741FQDBQRQ1 from Texas Instruments, in a SSOP-16-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC1 power_in Side-1 supply. 2.25 V to 5.5 V. Bypass locally to GND1 with 100 nF.
2 GND1 power_in Side-1 ground reference for VCC1.
3 INA input Side-1 logic input for forward channel A. VIH ≥ 0.7×VCC1, VIL ≤ 0.3×VCC1.
4 INB input Side-1 logic input for forward channel B. VIH ≥ 0.7×VCC1, VIL ≤ 0.3×VCC1.
5 INC input Side-1 logic input for forward channel C. VIH ≥ 0.7×VCC1, VIL ≤ 0.3×VCC1.
6 OUTD output Side-1 logic output for reverse channel D (data crosses isolation from side 2 to side 1). Default HIGH on loss of input power/signal (F variant).
7 EN1 input Side-1 output enable. High or open enables side-1 outputs; low places side-1 outputs in high-impedance.
8 GND1 power_in Second side-1 ground pin (tie to pin 2).
9 GND2 power_in Side-2 ground reference for VCC2.
10 EN2 input Side-2 output enable. High or open enables side-2 outputs; low places side-2 outputs in high-impedance.
11 IND input Side-2 logic input for reverse channel D. VIH ≥ 0.7×VCC2, VIL ≤ 0.3×VCC2.
12 OUTC output Side-2 logic output for forward channel C. Default HIGH on loss of input power/signal (F variant).
13 OUTB output Side-2 logic output for forward channel B. Default HIGH on loss of input power/signal (F variant).
14 OUTA output Side-2 logic output for forward channel A. Default HIGH on loss of input power/signal (F variant).
15 GND2 power_in Second side-2 ground pin (tie to pin 9).
16 VCC2 power_in Side-2 supply. 2.25 V to 5.5 V. Bypass locally to GND2 with 100 nF.
