ISO7640FMDWR

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

ISO7640FMDWR 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 Power supply for side 1 (VCC1), with a recommended supply range of 2.7 V to 5.5 V.
2 GND1 power_in Ground connection for VCC1 (isolated side 1 ground).
3 INA input Logic input, channel A; VIH is 2 V minimum and VIL is 0.8 V maximum.
4 INB input Logic input, channel B; VIH is 2 V minimum and VIL is 0.8 V maximum.
5 INC input Logic input, channel C; VIH is 2 V minimum and VIL is 0.8 V maximum.
6 IND input Logic input, channel D; VIH is 2 V minimum and VIL is 0.8 V maximum.
7 NC unconnected No connect; the pin is floating with no internal connection.
8 GND1 power_in Ground connection for VCC1 (isolated side 1 ground).
9 GND2 power_in Ground connection for VCC2 (isolated side 2 ground).
10 EN input Enables OUTA, OUTB, OUTC and OUTD when High or open, and disables them when Low (ISO7640 only).
11 OUTD output Output, channel D; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions.
12 OUTC output Output, channel C; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions.
13 OUTB output Output, channel B; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions.
14 OUTA output Output, channel A; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions.
15 GND2 power_in Ground connection for VCC2 (isolated side 2 ground).
16 VCC2 power_in Power supply for side 2 (VCC2), with a recommended supply range of 2.7 V to 5.5 V.
