ISO7761FDBQR

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

ISO7761FDBQR from Texas Instruments, in a SSOP-16-150mil. 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 Input-side power supply (2.25 V to 5.5 V with UVLO protection).
2 INA input Channel A isolated input, accepts CMOS logic levels 0 V to VCCI.
3 INB input Channel B isolated input, accepts CMOS logic levels 0 V to VCCI.
4 INC input Channel C isolated input, accepts CMOS logic levels 0 V to VCCI.
5 IND input Channel D isolated input, accepts CMOS logic levels 0 V to VCCI.
6 INE input Channel E isolated input, accepts CMOS logic levels 0 V to VCCI.
7 OUTF output Channel F isolated output (reverse direction), defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V.
8 GND1 power_in Ground reference for input-side power supply VCC1.
9 GND2 power_in Ground reference for output-side power supply VCC2.
10 INF input Channel F isolated input (reverse direction), accepts CMOS logic levels 0 V to VCCI.
11 OUTE output Channel E isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V.
12 OUTD output Channel D isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V.
13 OUTC output Channel C isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V.
14 OUTB output Channel B isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V.
15 OUTA output Channel A isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V.
16 VCC2 power_in Output-side power supply (2.25 V to 5.5 V with UVLO protection).
