DESCRIPTION HCF4054B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. PIN CONNECTION
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

can be converted to output signal swings (VDD to VEE) of +5V to -5V. The level shifted function permits the use of different input and output signal swings. The input swings from a low level of VSS to a high level of VDD, while the outputs swings from a low level of VEE to the same high level of VDD . Thus, the input and output swings can be IINPUT EQUIVALENT CIRCUIT selected independently of each other over a 3 to 18V range. VSS may be connected to V EE when no level-shift function is required. Data is transferred from input to output by placing a high voltage level at the strobe input. A low voltage level at the strobe input latches the data input and the corresponding output segments remain selected (or non selected) while the strobe is low. PIN DESCRIPTION
