SEMICONDUCTOR TECHNICAL DATA  
L SUFFIX  
CERAMIC  
CASE 620  
The MC14042B Quad Transparent Latch is constructed with MOS  
P–channel and N–channel enhancement mode devices in a single  
monolithic structure. Each latch has a separate data input, but all four  
latches share a common clock. The clock polarity (high or low) used to  
strobe data through the latches can be reversed using the polarity input.  
Information present at the data input is transferred to outputs Q and Q during  
the clock level which is determined by the polarity input. When the polarity  
input is in the logic “0” state, data is transferred during the low clock level,  
and when the polarity input is in the logic “1” state the transfer occurs during  
the high clock level.
