SEMICONDUCTOR TECHNICAL DATA
Industrial Time Base Generator
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 counting for generating 1.0 Hz from European 50 Hz line. Pin 11 = VDD will cause ÷ 5.
