Industrial Time Base Generator
The MC14566B industrial time base generator is constructed with MOS
Pâchannel and Nâchannel enhancement mode devices in a single
monolithic structure. This device consists of a divideâbyâ10 ripple counter
and a divideâbyâ5 or divideâbyâ6 ripple counter to permit stable time
generation from a 50 or 60 Hz line. By cascading this device as divideâbyâ60
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 divideâbyâ5
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 Lowâpower TTL Loads or One Lowâpower
ÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃ Schottky TTL Load Over the Rated Temperature Range
