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
