MC14566B
The MC14566B industrial time base generator is constructed with MOS
P–channel and N–channel enhancement mode d evices i n a single
monolithic structure. This device consists of a divide–by–10 ripple counter
and a divide–by–5 or d ivide–by–6 ripple counter to p ermit 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
Schottky TTL Load Over the Rated Temperature Range

†To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + (CL – 50) Vfk
where: IT is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.001.
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However,
precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance
circuit. For proper operation, Vin and V
out
should be constrained to the range VSS ≤ (Vin or V
out
) ≤ VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must
be left open.
