ISO7761DBQR from Texas Instruments, in a SSOP-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 input for input-side channel, operating range 2.25V to 5.5V with 0.1µF bypass capacitor to GND1 recommended. |
| 2 | INA | input | Digital input for channel A, accepts logic levels 0V to VCCI with VIH threshold of 0.7×VCCI and VIL threshold of 0.3×VCCI, supports data rates 0 to 100 Mbps. |
| 3 | INB | input | Digital input for channel B, accepts logic levels 0V to VCCI with VIH threshold of 0.7×VCCI and VIL threshold of 0.3×VCCI, supports data rates 0 to 100 Mbps. |
| 4 | INC | input | Digital input for channel C, accepts logic levels 0V to VCCI with VIH threshold of 0.7×VCCI and VIL threshold of 0.3×VCCI, supports data rates 0 to 100 Mbps. |
| 5 | IND | input | Digital input for channel D, accepts logic levels 0V to VCCI with VIH threshold of 0.7×VCCI and VIL threshold of 0.3×VCCI, supports data rates 0 to 100 Mbps. |
| 6 | INE | input | Digital input for channel E, accepts logic levels 0V to VCCI with VIH threshold of 0.7×VCCI and VIL threshold of 0.3×VCCI, supports data rates 0 to 100 Mbps. |
| 7 | OUTF | output | Digital output for channel F, provides logic levels from 0.2-0.4V (low) to VCCO-0.4V (high) minimum with 11ns typical propagation delay at 5V and 15pF load. |
| 8 | GND1 | power_in | Ground connection for input-side power supply VCC1, provides return path and reference for channels A through E. |
| 9 | GND2 | power_in | Ground connection for output-side power supply VCC2, provides return path and reference for all output channels. |
| 10 | INF | input | Digital input for channel F, accepts logic levels 0V to VCCI with VIH threshold of 0.7×VCCI and VIL threshold of 0.3×VCCI, supports data rates 0 to 100 Mbps. |
| 11 | OUTE | output | Digital output for channel E, provides logic levels from 0.2-0.4V (low) to VCCO-0.4V (high) minimum with 11ns typical propagation delay at 5V and 15pF load. |
| 12 | OUTD | output | Digital output for channel D, provides logic levels from 0.2-0.4V (low) to VCCO-0.4V (high) minimum with 11ns typical propagation delay at 5V and 15pF load. |
| 13 | OUTC | output | Digital output for channel C, provides logic levels from 0.2-0.4V (low) to VCCO-0.4V (high) minimum with 11ns typical propagation delay at 5V and 15pF load. |
| 14 | OUTB | output | Digital output for channel B, provides logic levels from 0.2-0.4V (low) to VCCO-0.4V (high) minimum with 11ns typical propagation delay at 5V and 15pF load. |
| 15 | OUTA | output | Digital output for channel A, provides logic levels from 0.2-0.4V (low) to VCCO-0.4V (high) minimum with 11ns typical propagation delay at 5V and 15pF load. |
| 16 | VCC2 | power_in | Power supply input for output-side channel, operating range 2.25V to 5.5V with 0.1µF bypass capacitor to GND2 recommended. |
