SEMICONDUCTOR TECHNICAL DATA  
L SUFFIX  
CERAMIC  
CASE 726  
CMOS MSI (Low–Power Complementary MOS)  
The MC14544B 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. The Ripple Blanking Input (RBI) and the Ripple  
Blanking Output (RBO) can be used to suppress either leading or trailing  
zeroes.
