Industrial Time Base Generator
The MC14566B industrial time base generator is constructed with MOS P c h a n n e l and Nchannel enhancement mode devices in a single monolithic structure. This device consists of a divideby10 ripple counter and a divideby5 or divideby6 ripple counter to permit stable time generation from a 50 or 60 Hz line. By cascading this device as divideby60 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 divideby5 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 Lowpower TTL Loads or One Lowpower 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 Vout should be constrained to the range VSS (Vin or Vout) 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.
