ONSEMI MC14543BDG Seven Segment Display Driver

The MC14543BDG is a CMOS BCD-to-seven segment latch, decoder, and driver integrated circuit designed primarily for liquid crystal (LC) display applications. It features a 4-bit storage latch and can invert output logic levels. The device includes phase, blanking, and latch disable inputs to control display timing, blanking of invalid input codes, and data storage respectively. When used with LC displays, a square wave applied to the phase input synchronizes with the display's backplane, and the outputs connect directly to the segments. The IC also supports driving other readout types such as LEDs, incandescent, gas discharge, and fluorescent displays, with specific connection guidelines provided. Additional features include latch storage, blanking of illegal inputs, and direct driving capability for LED displays. It is a pin-compatible replacement for the CD4056A (with pin 7 tied to ground) and is suitable for applications in consumer electronics, clocks, and timing systems.
