DESCRIPTION

HCF4054B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. HCF4054B provides level shifting similar to

HCF4055B and HCF4056B, independently strobed latches, and common DF control on 4signal 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 (V DD to V SS ) from +5V to 0V

can be converted to output signal swings (V DD to V EE ) 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 V SS to a high level of V DD, while the outputs swings from a low level of V EE to the same high level of V DD . Thus, the input and output swings can be selected independently of each other over a 3 to 18V range. V SS 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.
