Features
| • | Independently drives two N-Channel MOSFETs |
| • | Compound CMOS and bipolar outputs reduce output current variation |
| • | 5A sink/3A source current capability |
| • | Two channels can be connected in parallel to double the drive current |
| • | Independent inputs (TTL compatible) |
| • | Fast propagation times (25 ns typical) |
| • | Fast rise and fall times (14 ns/12 ns rise/fall with 2 nF load) |
| • | Dedicated input ground pin (IN_REF) for split supply or single supply operation |
| • | Outputs swing from VCC to VEE which can be negative relative to input ground |
| • | Available in dual non-inverting, dual inverting and combination configurations |
| • | Shutdown input provides low power mode |
| • | Supply rail under-voltage lockout protection |
| • | Pin-out compatible with industry standard gate drivers |
