SEMICONDUCTOR TECHNICAL DATA  
L SUFFIX  
CERAMIC  
CASE 620  
The MC14566B industrial time base generator is constructed with MOS  
P–channel and N–channel enhancement mode devices in a single  
monolithic structure. This device consists of a divide–by–10 ripple counter  
and a divide–by–5 or divide–by–6 ripple counter to permit stable time  
generation from a 50 or 60 Hz line. By cascading this device as divide–by–60  
counters, seconds and minutes can be counted and are available in BCD  
format at the circuit outputs. An internal monostable multivibrator is included  
whose output can be used as a reset or clock pulse providing additional  
frequency flexibility. Also a pin has been included to allow divide–by–5
