BCD-to-Seven 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. Latch Storage of Code Blanking Input Readout Blanking on All Illegal Input Combinations Direct LED (Common Anode or Cathode) Driving Capability Supply Voltage Range = 3.0 V to 18 V Capable of Driving 2 Low–power TTL Loads, 1 Low–power Schottky
