CD4543 – BCD to 7 Segment Decoder IC<\/h2>\n

The CD4543 is a BCD-to-seven segment latch\/decoder\/driver IC 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 and serves as a direct replacement for the CD4056 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.<\/p>\n

When the CD4056 is used in the level shifting mode, two power supplies are required. When the CD4543 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 logic 1 is required at the PHASE input for common-cathode devices; logic 0 is required for common-anode devices (see truth table). The CD4543B is supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).<\/p>\n
