ISO7241CDWR

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

ISO7241CDWR from Texas Instruments, in a SOIC-16-300mil. 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 Positive power supply pin for input isolation side with operating voltage range 3.15V to 5.5V.
2 GND1 power_in Ground connection for input side power supply VCC1.
3 INA input Channel A input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V.
4 INB input Channel B input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V.
5 INC input Channel C input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V.
6 OUTD output Channel D output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA.
7 EN1 input Output enable 1 control; high or open enables channel outputs on side 1, low disables to high-impedance.
8 GND1 power_in Ground connection for input side power supply VCC1.
9 GND2 power_in Ground connection for output side power supply VCC2.
10 EN2 input Output enable 2 control; high or open enables channel outputs on side 2, low disables to high-impedance.
11 IND input Channel D input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V.
12 OUTC output Channel C output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA.
13 OUTB output Channel B output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA.
14 OUTA output Channel A output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA.
15 GND2 power_in Ground connection for output side power supply VCC2.
16 VCC2 power_in Positive power supply pin for output isolation side with operating voltage range 3.15V to 5.5V.
