HCF4054B provides level shifting similar to HCF4055B and HCF4056B, independently strobed latches, and common DF control on 4 signal lines. This device is intended to provide drive signal compatibility with HCF4055B and HCF4056B 7-segment decoder types for the decimal point, colon, polarity, and similar display lines. A level-shifted high amplitude DF output can be obtained from any HCF4054B output line by connecting the corresponding input and strobe lines to a low and high levels. HCF4054B may also be utilized for logic level "up conversion" or "down conversion" respectively. For example, input signal swings (VDD to VSS) from +5V to 0V HCF4054B 4 SEGMENT LIQUID CRYSTAL DISPLAY DRIVER WITH STROBED LATCH FUNCTION PIN CONNECTION ORDER CODES PACKAGE TUBE T & R DIP HCF4054BEY SOP HCF4054BM1 HCF4054M013TR DIP SOP |
