Description of HCC4054B/55B/56B HCF4054B/55B/56B Liquid-Crystal Display Drivers. Quiescent current specified to 20V for HCC device. Operation of liquid crystals with COS/MOS circuits provides ultra-low-power displays. Equivalent AC output drive for liquid-crystal displays-no external capacitor required. Voltage doubling across display [(VDD – VEE) = 18V)] results in effective 36V (p-p) drive across selected display segments. Low- or high-output level DC drive for other types of displays. On-chip logic-level conversion for different input and output-level swings. Full decoding of all input combinations: “0-9, L, H, P, A–” and blank positions. Input current of 100nA at 18V and 25°C for HCC device. 100% tested for quiescent current. Meets all requirements of JEDECTEN tative standard N°. 13A, “Standard Specifications for Description of “B” Series CMOS Devices”.
