CD4543B - IC to Control Both Common Anode and Common Cathode SSDs

by realfinetime  |  in IC REVIEW at  21:49

CD4543B is a BCD-to-seven segment display latch/decoder/driver designed for Liquid Crystal Display Applications. It is also capable of  driving light emitting diode, incandescent, gas-discharge and fluorescent displays.

Most amazing feature of  CD4543B is it's ability to control Common Anode as well as Common Cathode seven segment displays. A logic 0 is required at the phase input (PH) for common-cathode devices and a logic 1 is required at the phase input (PH) for common anode devices.

LD - Latch Disable
PH - Phase
BL - Blanking
