HD74HC4543 BCD-to-Seven Segment Latch/Decoder/Driver REJ03D0655-0200 (Previous ADE-205-544) Rev.2.00 Mar 30, 2006 Description This circuit contains a 4-bit latch, BCD-to-7 segment decoder, and 7 output drivers. Data on the input pins flow through to the output when the Latch Disable (LE) is high and is latched on the high to low transition of the LE input. The Phase input (Ph) controls the polarity of the 7 segment outputs. When Ph is low the outputs are true 7 segment, and when Ph is high the outputs are inverted 7 segment. When the Phase input is driven by a liquid crystal display (LCD) backplane waveform the segment pins output the correct segment waveform for proper LCD AC drive voltages. In addition a Blanking input (BI) is provided, which will blank the display.
