XC74 series products are 74 series of small-sized encapsulates the multichannel ChanMen logic circuit IC.

Because did effective use need the gate number, so lowers the cost and realized the minimal installation area.

XC74UH series products CMOS manufacturing process has the characteristic of low electricity consumption can achieve the same with the LS - TTL high-speed work.

XC74UL series products CMOS manufacturing process with the LS can be realized as high-speed work - TTL, has less power consumption and can improve the processing speed characteristic. Because the power supply voltage above can be added in the input voltage, can achieve a 3V system from 5V level transformation. Can SSOT25 super-mini moulding package.
