MM54HC4543, MM74HC4543
BCD-to-7 Segment Latch/Decoder/Driver for LCDs
The MM54HC4543/MM74HC4543 BCD-to-7 segment latch/decoder/driver utilize advanced silicon-
gate CMOS technology, and can be used either as a high speed decoder or as a display driver. This
circuit contains a 4-bit latch, BCD-to-7 segment decoder, and 7 output when the LATCH ENABLE
(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, and when PH is high the outputs are inverted 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.
