ISO6742FQDWRQ1

Texas Instruments · Digital Isolators · SOIC-16

ISO6742FQDWRQ1 from Texas Instruments, in a SOIC-16. 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 Power supply for input side, voltage range 1.71-1.89V or 2.25-5.5V.
2 GND1 power_in Ground connection for VCC1 input side.
3 INA input Digital input for channel A, accepts CMOS logic high ≥0.7×VCCI and low ≤0.3×VCCI.
4 INB input Digital input for channel B, accepts CMOS logic high ≥0.7×VCCI and low ≤0.3×VCCI.
5 OUTC tri_state Output for channel C, tri-state output controlled by EN1, drives 0V to VCCO.
6 OUTD tri_state Output for channel D, tri-state output controlled by EN1, drives 0V to VCCO.
7 EN1 input Output enable input for side 1; high or open enables outputs, low forces high-impedance state.
8 GND1 power_in Ground connection for VCC1 input side.
9 GND2 power_in Ground connection for VCC2 output side.
10 EN2 input Output enable input for side 2; high or open enables outputs, low forces high-impedance state.
11 IND input Digital input for channel D, accepts CMOS logic high ≥0.7×VCCI and low ≤0.3×VCCI.
12 INC input Digital input for channel C, accepts CMOS logic high ≥0.7×VCCI and low ≤0.3×VCCI.
13 OUTB tri_state Output for channel B, tri-state output controlled by EN2, drives 0V to VCCO.
14 OUTA tri_state Output for channel A, tri-state output controlled by EN2, drives 0V to VCCO.
15 GND2 power_in Ground connection for VCC2 output side.
16 VCC2 power_in Power supply for output side, voltage range 1.71-1.89V or 2.25-5.5V.
