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.
Features
Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
