ISO7842DWR

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

ISO7842DWR 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 pin for input side of isolator, 2.25V to 5.5V.
2 GND1 power_in Ground connection for VCC1 on input side.
3 INA input Input signal for channel A, high level voltage VIH = 0.7×VCCI, low level voltage VIL = 0.3×VCCI.
4 INB input Input signal for channel B, high level voltage VIH = 0.7×VCCI, low level voltage VIL = 0.3×VCCI.
5 OUTC output Output signal for channel C, high level voltage VOH = VCCO - 0.2V typical, low level voltage VOL = 0.4V typical.
6 OUTD output Output signal for channel D, high level voltage VOH = VCCO - 0.2V typical, low level voltage VOL = 0.4V typical.
7 EN1 input Output enable 1, when high or open enables side 1 output pins, when low output is in high impedance state.
8 GND1 power_in Ground connection for VCC1 on input side.
9 GND2 power_in Ground connection for VCC2 on output side.
10 EN2 input Output enable 2, when high or open enables side 2 output pins, when low output is in high impedance state.
11 IND input Input signal for channel D, high level voltage VIH = 0.7×VCCI, low level voltage VIL = 0.3×VCCI.
12 INC input Input signal for channel C, high level voltage VIH = 0.7×VCCI, low level voltage VIL = 0.3×VCCI.
13 OUTB output Output signal for channel B, high level voltage VOH = VCCO - 0.2V typical, low level voltage VOL = 0.4V typical.
14 OUTA output Output signal for channel A, high level voltage VOH = VCCO - 0.2V typical, low level voltage VOL = 0.4V typical.
15 GND2 power_in Ground connection for VCC2 on output side.
16 VCC2 power_in Power supply pin for output side of isolator, 2.25V to 5.5V.
