DIP SOP ORDER CODES PACKAGE TUBE T&R DIP SOP HCF4054BEY HCF4054BM1 HCF4054M013TR 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 PIN CONNECTION September 2002 1/11 HCF4054B 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 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.
