ISO7820LLDWR

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

ISO7820LLDWR 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); recommended supply range is 2.25 V to 5.5 V, and absolute maximum is 6 V.
2 GND1 power_in Ground connection for VCC1 on side 1.
3 INA+ input Positive differential input for channel A (LVDS RX); the RX differential input magnitude is specified at 100 mV to 600 mV.
4 INA- input Negative differential input for channel A (LVDS RX); the RX differential input magnitude is specified at 100 mV to 600 mV.
5 INB- input Negative differential input for channel B (LVDS RX); the RX differential input magnitude is specified at 100 mV to 600 mV.
6 INB+ input Positive differential input for channel B (LVDS RX); the RX differential input magnitude is specified at 100 mV to 600 mV.
7 NC unconnected Not connected on the ISO7820LL.
8 GND1 power_in Ground connection for VCC1 on side 1.
9 GND2 power_in Ground connection for VCC2 on side 2.
10 EN2 input Output enable 2: side 2 outputs are enabled when EN2 is high or open and are in high impedance when EN2 is low.
11 OUTB+ output Positive differential output for channel B (LVDS TX); maximum current through OUTx pins is ±20 mA.
12 OUTB- output Negative differential output for channel B (LVDS TX); maximum current through OUTx pins is ±20 mA.
13 OUTA- output Negative differential output for channel A (LVDS TX); maximum current through OUTx pins is ±20 mA.
14 OUTA+ output Positive differential output for channel A (LVDS TX); maximum current through OUTx pins is ±20 mA.
15 GND2 power_in Ground connection for VCC2 on side 2.
16 VCC2 power_in Power supply for side 2 (VCC2); recommended supply range is 2.25 V to 5.5 V, and absolute maximum is 6 V.
