HCF4543B Overview
The HCC/HCF4543B is a BCD-to-seven segment latch/decoder/driver designed primarily for liquidcrystal display (LCD) applications. It is also capable of driving light emitting diode (LED), incandescent, gas-discharge, and fluorescent displays. This device is functionally similar to and serves as direct replacement for the HCF4056B when pin 7 is connected to VSS.
