Six Decade Counter / Display Decoder  
Not Recommended for New Designs  
General Description  
Features  
The MIC50395 is an ion-implanted, P-channel MOS six-  
decade synchronous up/down-counter/display driver with  
compare-register and storage-latches. The counter as well  
as the register can be loaded digit-by-digit with BCD data.  
The counter has an asynchronous-clear function.

Six decades of synchronous up/down counting  
Look-ahead carry or borrow  
Loadable counter  
Scanning is controlled by the scan oscillator input which is  
self-oscillating or can be driven by an external signal. The  
six-decade register is constantly compared to the state of  
the six-decade counter and when both the register and the  
counter have the same content, an EQUAL signal is gener-  
ated. The contents of the counter can be transferred into the  
6-digit latch which is then multiplexed from MSD to LSD in  
BCD and 7-segment format to the output. The seven-  
segment decoder incorporates a leading-zero blanking  
circuit which can be disabled by an external signal. This  
device is intended to interface directly with the standard  
CMOS logic families.

Ordering Information  
The MIC50396 and MIC50397 operate identically to the  
MIC50395 except that two digits in each were reprogrammed  
to provide divide by six circuitry instead of divide by ten. The  
MIC50396 is well suited for industrial timer applications while  
the MIC50397 is best suited for stop watch or real time  
computer clock applications.
