DESCRI PTION

The HCC/HCF4543B is a BCD-to-seven segment
latch/decoder/driver designed primarily for liquid­crystaldisplay(LCD) applications. It isalso capable
of driving light emitting diode (LED), incandescent,
gas-discharge, and fluorescent displays. This de­viceis functionally similar to andservesas direct re­placement for the HCF4056B when pin 7 is
connected to VSS. It differsfrom the HCF4056B in
that it has a displayblanking capability instead of a
level-shifting function and requires only one power
supply. When the HCF4056B is used in the level
shifting mode, two power supplies are required.
When the HCF4543B isused for LCD applications,
a squarewave mustbe applied to thePHASEinput
and the backplane of the LCD device.For LED ap­plications a logic 1 is required at the PHASE input
for common-cathode devices ; a logic 0 is required
for common-anode devices (see truthtable).
