Data Sheet
BCD-to-Seven Segment Latch/Decoder/Driver for Liquid Crystals
Device MC14543B
BCD-to-7 Segment Latch/Decoder/Driver for Liquid Crystals
The MC14543B BCD-to-seven segment latch/decoder/driver is 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.
Applications include instrument (e.g., counter, DVM etc.) display driver, computer/calculator display driver, cockpit display
driver, and various clock, watch, and timer uses.
