DESCRIPTION
CD4543B 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 device is
functionally similar to and serves as direct replacement for the CD4056B when pin 7 is connected to VSS. It differs from the
CD4056B in that it has a display blanking capability instead of a level-shifting function and requires only one power supply.
When the CD4056B is used in the level shifting mode, two power supplies are required. When the CD4543B is used for LCD
applications, a square wave must be applied to the PHASE input 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
truth table).
The CD4543B is supplied in hermetic dual-in-line ceramic packages (D and F suffixes), 16-lead dual-in-line plastic packages
(E suffix), 16-lead small-outline package (NSR suffix), and in chip form (H suffix).
