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 = V DD will
cause
5.
Negative Edge Triggered Counters for Ease of Cascading
Pulse Shapers on Counter Inputs Accept Slow Input Rise Times
Monostable Multivibrator Positive or Negative Edge Triggered
Diode Protection on All Inputs
Supply Voltage Range = 3.0 Vdc to 18 Vdc
Capable of Driving Two Low–power TTL Loads or One Low–power
