DESCRIPTION

The HCC/HCF4543B is a BCD-to-seven segment

latch/decoder/driver designed primarily for liquid-

crystal display (LCD) applications. It is also capable

of driving light emitting diode (LED), incandescent,

gas-discharge, and fluorescent displays. This de-

vice is functionally similar to and serves as direct re-

placement for the HCF4056B when pin 7 is

connected to V

that it has a display blanking 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 is used for LCD applications,

a square wave must be applied to the PHASE input

and the backplane of the LCD device. For LED ap-

plications a logic 1 is required at the PHASE input

for common-cathode devices ; a logic 0 is required

for common-anode devices (see truth table).
