Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIA | input | Logic input A, a CMOS input referenced to GND1 with absolute maximum range of −0.5 V to VDD1 + 0.5 V. |
| 2 | VIB | input | Logic input B, a CMOS input referenced to GND1 with absolute maximum range of −0.5 V to VDD1 + 0.5 V. |
| 3 | VDD1 | power_in | Input supply voltage, recommended 3.0 V to 5.5 V; internally connected to pin 8, and both pins should be connected to VDD1. |
| 4 | GND1 | power_in | Ground reference for the input logic signals. |
| 5 | DISABLE | input | Input disable: when driven high the input isolator is disabled and the outputs go to the default low state within 3 µs, and they return to the input state within 1 µs after DISABLE is set low. |
| 6 | NC | unconnected | No connect; do not connect to this pin. |
| 7 | NC | unconnected | No connect; do not connect to this pin. |
| 8 | VDD1 | power_in | Input supply voltage, recommended 3.0 V to 5.5 V; internally connected to pin 3, and both pins should be connected to VDD1. |
| 9 | GNDB | power_in | Ground reference for output B. |
| 10 | VOB | output | Output B driver, rated for 4 A peak output current with a gate driver supply of 4.5 V to 18 V (VDDB). |
| 11 | VDDB | power_in | Output B supply voltage, recommended 4.5 V to 18 V, with absolute maximum of −0.5 V to +20 V. |
| 12 | NC | unconnected | No connect; do not connect to this pin. |
| 13 | NC | unconnected | No connect; do not connect to this pin. |
| 14 | GNDA | power_in | Ground reference for output A. |
| 15 | VOA | output | Output A driver, rated for 4 A peak output current with a gate driver supply of 4.5 V to 18 V (VDDA). |
| 16 | VDDA | power_in | Output A supply voltage, recommended 4.5 V to 18 V, with absolute maximum of −0.5 V to +20 V. |
