4BIT MICRO CONTROLLER

Description The SD4002 is CMOS LSI chips developed for world-wide FM / MW / LW tuning with PLL frequency synthesizer system. The SD4002 can make a compact and high performance FM / MW / LW tuner with clock function for high-end car stereo, home stereo and so on because these CMOS LSIs are in 64-p

18V/2A同步降压转换器

The SD4002 is a fully integrated, high efficiency 2A synchronous rectified step-down converter. The SD4002 operates at high efficiency over a wide output current load range. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wi • High Efficiency: Up to 98%\n• 2A Output Current\n• 4.0V to 18V Input Voltage Range\n• Slope Compensated Current Mode Control for Excellent\n• Integrated internal compensation\n• Over Current Protection with Hiccup-Mode\n• Inrush Current Limit and Soft Start\n• -40°C to +85°C Temperature Range\;

Dual 4-input NOR gate

DESCRIPTION The HEF4002B provides the positive dual 4-input NOR function. The outputs are fully buffered for highest noise immunity and pattern insensitivity of output impedance.
