HX4424-S from ZHHXDZ, in a SOP-8. 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 | NC | unconnected | No connection; the pin table lists it as NC with no function assigned. |
| 2 | IN A | input | Input A is a high-impedance, TTL/CMOS compatible MOSFET driver input with 300 mV hysteresis between its high and low thresholds, which prevents output glitching even on very slow input edges, and OUT A is the inverse of this input. |
| 3 | GND | power_in | Ground is the device return pin and should have a low-impedance connection to the bias supply return, since high peak current flows out of this pin when the capacitive load discharges; the device withstands noise spikes of up to 5 V on the ground pin regardless of polarity. |
| 4 | IN B | input | Input B is a high-impedance, TTL/CMOS compatible MOSFET driver input with 300 mV hysteresis between its high and low thresholds, which prevents output glitching even on very slow input edges, and OUT B is the inverse of this input. |
| 5 | OUT B | output | Output B is a low-impedance CMOS push-pull output whose pull-up and pull-down devices are of equal strength, and it is held LOW if Input B is unbiased or floating. |
| 6 | VDD | power_in | VDD is the bias supply for the driver, rated 4.5 V to 25 V with respect to GND, and should be bypassed with local ceramic capacitors (1.0 µF suggested, sized to the capacitive load). |
| 7 | OUT A | output | Output A is a low-impedance CMOS push-pull output whose pull-up and pull-down devices are of equal strength, and it is held LOW if Input A is unbiased or floating. |
| 8 | NC | unconnected | No connection; the pin table lists it as NC with no function assigned. |
