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.

• 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
