DESCRIPTION

· HCF4054B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, available in DIP and SOP packages.
· It provides level shifting, independently strobed latches, and common DF control on 4 signal lines.
· Designed for drive signal compatibility with HCF4055B and HCF4056B 7-segment decoder types for decimal point, colon, polarity, and similar display lines.
· Can be used for logic level "up conversion" or "down conversion".

FEATURES

· Quiescent current specification up to 20V.
· Operation of liquid crystals with CMOS circuits provides ultra-low power displays.
· Equivalent AC output drive for liquid crystal displays - no external capacitor required.
· Voltage doubling across display results in effective 36V (p-p) drive across selected display segments.
· Low or high output level DC drive for other types of displays.
· One-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 leakage current II = 100nA (max) at VDD = 18V, TA = 25°C.
· 100% tested for quiescent current.
· Meets all requirements of JEDEC JESD13B "Standard Specifications for Description of B Series CMOS Devices".

APPLICATIONS

· Drive signal compatibility with HCF4055B and HCF4056B 7-segment decoder types.
· Level-shifted high amplitude DF output from any HCF4054B output line.
· Logic level conversion for different input and output level swings.
