Product Summary

The HEF4543BT is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an active HIGH blanking input (BL), an active HIGH phase input (PH) and seven buffered segment outputs (Qa to Qg). The HEF4543BT can invert the logic levels of the output combination. The phase (PH), blanking (BL) and latch enable (LE) inputs are used to reverse the function table phase, blank the display and store a BCD code, respectively. The HEF4543BT operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over the full industrial (−40℃ to +85℃)temperature range.
