ISO6742DWR

Texas Instruments · Digital Isolators · SOIC-16-300mil

ISO6742DWR from Texas Instruments, in a SOIC-16-300mil. 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 Side 1 supply; the datasheet allows 1.71 V to 1.89 V or 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor placed within 2 mm of the pin.
2 GND1 power_in Ground connection for the side 1 supply VCC1.
3 INA input Channel A input on side 1; logic-high input is 0.7 × VCCI minimum and logic-low input is 0.3 × VCCI maximum.
4 INB input Channel B input on side 1; logic-high input is 0.7 × VCCI minimum and logic-low input is 0.3 × VCCI maximum.
5 OUTC output Channel C reverse-direction output on side 1, driven from INC on side 2 and enabled by EN1.
6 OUTD output Channel D reverse-direction output on side 1, driven from IND on side 2 and enabled by EN1.
7 EN1 input Output enable for side 1; high or open enables the side 1 outputs (OUTC, OUTD), and low forces them to high impedance.
8 GND1 power_in Ground connection for the side 1 supply VCC1 (second side 1 ground pin).
9 GND2 power_in Ground connection for the side 2 supply VCC2 (first side 2 ground pin).
10 EN2 input Output enable for side 2; high or open enables the side 2 outputs (OUTA, OUTB), and low forces them to high impedance.
11 IND input Channel D reverse-direction input on side 2; logic-high input is 0.7 × VCCI minimum and logic-low input is 0.3 × VCCI maximum.
12 INC input Channel C reverse-direction input on side 2; logic-high input is 0.7 × VCCI minimum and logic-low input is 0.3 × VCCI maximum.
13 OUTB output Channel B forward-direction output on side 2, driven from INB and enabled by EN2.
14 OUTA output Channel A forward-direction output on side 2, driven from INA and enabled by EN2.
15 GND2 power_in Ground connection for the side 2 supply VCC2 (second side 2 ground pin).
16 VCC2 power_in Side 2 supply; the datasheet allows 1.71 V to 1.89 V or 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor placed within 2 mm of the pin.
