Part Details:

HCF4054B 4 SEGMENT LIQUID CRYSTAL DISPLAY DRIVER WITH STROBED LATCH FUNCTION s QUIESCENT CURRENT SPECIF. UP TO 20V s OPERATION OF LIQUID CRYSTALS WITH CMOS CIRCUITS PROVIDES ULTRA LOW POWER DISPLAYS s EQUIVALENT AC OUTPUT DRIVE FOR LIQUID CRYSTAL DISPLAYS - NO EXTERNAL CAPACITOR REQUIRED DIP SOP s VOLTAGE DOUBLING ACROSS DISPLAY [(VDD - VEE) = 18V] RESULTS IN EFFECTIVE 36V (p-p) DRIVE ACROSS SELECTED ORDER CODES DISPLAY SEGMENTS PACKAGE TUBE T & R s LOW OR HIGH OUTPUT LEVEL DC DRIVE FOR OTHER TYPES OF DISPLAYS DIP HCF4054BEY s ONE CHIP LOGIC LEVEL CONVERSION SOP HCF4054BM1 HCF4054M013TR FOR DIFFERENT INPUT AND OUTPUT LEVEL SWINGS s FULL DECODING OF ALL INPUT HCF4054B provides level shifting similar to COMBINATIONS : "0 - 9, L, H, P, A" AND HCF4055B and HCF4056B, independently BLANK POSITIONS strobed latches, and common DF control on 4 s INPUT LEAKAGE CURRENT signal lines. This device is intended to provide II = 100nA (MAX) AT VDD = 18V TA = 25°C drive signal compatibility with HCF4055B and s 100% TESTED FOR QUIESCENT CURRENT HCF4056B 7-segment decoder types for the s MEETS ALL REQUIREMENTS OF JEDEC decimal point, colon, polarity, and similar display JESD13B "STANDARD SPECIFICATIONS lines. A level-shifted high amplitude DF output can FOR DESCRIPTION OF B SERIES CMOS be obtained from any HCF4054B output line by DEVICES" connecting the corresponding input and strobelines to a low and high levels. HCF4054B may DESCRIPTION also be utilized for logic level "up conversion" or
