NSG4427P

WXNSIC · Power Distribution Switches · DIP-8

NSG4427P from WXNSIC, in a DIP-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 Unconnected (empty) pin with no internal connection; the datasheet notes unused pins may be tied to VDD or GND in noisy environments to prevent output faults.
2 INA input Channel A logic input (level-triggered, non-inverting with OUTA); the datasheet states it withstands -10 V and VCC+0.3 V maximum, with VIH min 2.4 V and VIL max 0.8 V, and recommends shorting to GND when unused.
3 GND power_in Ground reference for all voltage ratings; the datasheet recommends a single star-point ground connection with short, wide traces.
4 INB input Channel B logic input (level-triggered, non-inverting with OUTB); the datasheet states it withstands -10 V and VCC+0.3 V maximum, with VIH min 2.4 V and VIL max 0.8 V, and recommends shorting to GND when unused.
5 OUTB output Channel B driver output with 2 A peak source/sink current, intended to drive the gate of a P- or N-channel MOSFET and to be placed close to the MOSFET gate.
6 VCC power_in Supply pin; the datasheet gives a recommended supply range of 4.5 V to 20 V with an absolute maximum of 25 V, and recommends low-ESR bulk and ceramic decoupling placed close to VCC and GND.
7 OUTA output Channel A driver output with 2 A peak source/sink current, intended to drive the gate of a P- or N-channel MOSFET and to be placed close to the MOSFET gate.
8 NC unconnected Unconnected (empty) pin with no internal connection; the datasheet notes unused pins may be tied to VDD or GND in noisy environments to prevent output faults.
