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.
