The MM74C85 is a four-bit magnitude comparator which will perform comparison of straight binary or BCD codes

This document describes a low-end vacuum cleaner demonstration board based on ST7FLiteUS5 and BTB12. It features an AC motor speed regulation system, high current protection, full bag checking, start/stop button, potentiometer (speed adjustment), LED checking, and sense resistor (current sensing). The board is designed for universal motor driving based on phase angle control and can be easily adapted for vacuum cleaner, home appliance, or industrial applications. The electronic driver with TRIAC and microcontroller is cost-effective and easy to implement. Microcontroller designs are replacing analog solutions even in low-cost applications due to their advantages of soft-start function, compliance with IEC 61000-3-3 standard on inrush currents, flexibility, fewer external components, and easy adaptation through simple software modifications.

MM54C74/MM74C74 is a dual D flip-flop. It is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. Each flip-flop has independent data, preset, clear and clock inputs and Q and Q outputs. The logic level present at the data input is transferred to the output during the positive going transition of the clock pulse. Preset or clear is independent of the clock and accomplished by a low level at the preset or clear input.

This document describes a 20W dimmable CFL (compact fluorescent lamp) ballast solution that can completely replace incandescent lamps in dimming systems. The dimming range of this solution is from below 20% up to 100% of full light output without changing the triac dimmer. Compared to traditional CFL designs, this dimmable solution not only provides energy savings but also higher reliability and longer operating life.
