BCD-to-Seven Segment Latch/Decoder/Driver
Description
This circuit contains a 4-bit latch, BCD-to-7 segment decoder, and 7 outpt 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.
