NY8 Series
 
Description

NY8series adopts advanced CMOS technology to provide customers remarkable solution with low cost, high performance and high noise immunity benefits. As NY8 address I/O type applications, each I/O pin may have additional features, like Pull-High/Pull-Low resistor and open-drain output type through programming. Moreover, NY8 series has built-in large infrared (IR) carrier generator (340mA@3V) with selectable IR carrier frequency and polarity for applications which demand remote control feature. Therefore, NY8 series is very suitable for those applications that are sophisticated but compact program size is required.
