MC14543B

BCD-to-Seven Segment

Latch/Decoder/Driver for

Liquid Crystals

designed for use with liquid crystal readouts, and is constructed with

complementary MOS (CMOS) enhancement mode devices. The

circuit provides the functions of a 4−bit storage latch and an 8421

BCD−to−seven segment decoder and driver. The device has the

capability to invert the logic levels of the output combination. The

phase (Ph), blanking (BI), and latch disable (LD) inputs are used to

reverse the truth table phase, blank the display, and store a BCD code,

respectively. For liquid crystal (LC) readouts, a square wave is applied

to the Ph input of the circuit and the electrically common backplane of

the display. The outputs of the circuit are connected directly to the

segments of the LC readout. For other types of readouts, such as

light−emitting diode (LED), incandescent, gas discharge, and

fluorescent readouts, connection diagrams are given on this data sheet.

driver, computer/calculator display driver, cockpit display driver, and

various clock, watch, and timer uses.
