Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Side-1 supply voltage, specified at 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC1 and GND1. |
| 2 | GND1 | power_in | Ground connection for the side-1 supply VCC1. |
| 3 | INA | input | Logic input for channel A on side 1; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum. |
| 4 | INB | input | Logic input for channel B on side 1; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum. |
| 5 | INC | input | Logic input for channel C on side 1; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum. |
| 6 | OUTD | output | Output of channel D on side 2, which follows the channel D input logic state while its output is enabled. |
| 7 | EN1 | input | Output enable for side 1: driving EN1 high or leaving it open enables the side-1 outputs, and driving it low places them in high impedance. |
| 8 | GND1 | power_in | Ground connection for the side-1 supply VCC1. |
| 9 | GND2 | power_in | Ground connection for the side-2 supply VCC2. |
| 10 | EN2 | input | Output enable for side 2: driving EN2 high or leaving it open enables the side-2 outputs, and driving it low places them in high impedance. |
| 11 | IND | input | Logic input for channel D on side 2; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum. |
| 12 | OUTC | output | Output of channel C on side 2, which follows the channel C input logic state while its output is enabled. |
| 13 | OUTB | output | Output of channel B on side 2, which follows the channel B input logic state while its output is enabled. |
| 14 | OUTA | output | Output of channel A on side 2, which follows the channel A input logic state while its output is enabled. |
| 15 | GND2 | power_in | Ground connection for the side-2 supply VCC2. |
| 16 | VCC2 | power_in | Side-2 supply voltage, specified at 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC2 and GND2. |
