ISO7821LLDWW

Texas Instruments · Isolated LVDS Buffers · SOIC-16

ISO7821LLDWW from Texas Instruments, in a SOIC-16. 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) of the isolation barrier.
2 GND1 power_in Ground connection for VCC1 (side 1).
3 INA+ input Positive differential input, channel A.
4 INA- input Negative differential input, channel A.
5 OUTB- output Negative differential output, channel B.
6 OUTB+ output Positive differential output, channel B.
7 EN1 input Output enable 1: side-1 output pins are enabled when EN1 is high or open and are high impedance when EN1 is low.
8 GND1 power_in Ground connection for VCC1 (side 1).
9 GND2 power_in Ground connection for VCC2 (side 2).
10 EN2 input Output enable 2: side-2 output pins are enabled when EN2 is high or open and are high impedance when EN2 is low.
11 INB+ input Positive differential input, channel B.
12 INB- input Negative differential input, channel B.
13 OUTA- output Negative differential output, channel A.
14 OUTA+ output Positive differential output, channel A.
15 GND2 power_in Ground connection for VCC2 (side 2).
16 VCC2 power_in Power supply for side 2 (VCC2) of the isolation barrier.
