Product Overview

The CD4543BE 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.
  • Display blanking of all illegal input combinations
  • Latch storage of code
  • Pin-for-pin replacement for CD4056B (with pin 7 tied to VSS)
  • Direct LED driving capability
  • 100% Tested for quiescent current at 20V
  • Maximum input current of 1µA at 18V over full package-temperature range, 100nA at 18V and 25°C
  • 5, 10 and 15V Parametric ratings
