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. |
