SEMICONDUCTOR TECHNICAL DATA  
The MC14508B dual 4–bit latch is constructed with MOS P–channel and  
N–channel enhancement mode devices in a single monolithic structure. The  
part consists of two identical, independent 4–bit latches with separate Strobe  
(ST) and Master Reset (MR) controls. Separate Disable inputs force the  
outputs to a high impedance state and allow the devices to be used in time  
sharing bus line applications.  
These complementary MOS latches find primary use in buffer storage,  
holding register, or general digital logic functions where low power  
dissipation and/or high noise immunity is desired.
