The WK2204-IQNG is an integrated circuit (IC) manufactured by WEIKAI. It is a specialized QFN-24 RoHS package, which is a 24-pin surface-mount package with a Quad Flat No-Lead (QFN). The circuit features an 8-bit Line Driver with an active low SCK signal, non-inverting push-pull output, and internal pull-up resistors. The output impedance is 400 Ohms. The device provides an output voltage range of 0 to 6.5 Volts, and guarantees a high level output current of 90 mA. It is ideal for use in applications where low power consumption, low noise, and high speed are the utmost priorities. The WK2204-IQNG is RoHS (Restriction of Hazardous Substances) compliant and can operate within a temperature range of -40°C to +125°C.
