14-Bit Binary Counter
The MC14020B 14−stage binary counter is constructed with MOS
P−Channel and N−Channel enhancement mode devices in a single
monolithic structure. This part is designed with an input wave shaping
circuit and 14 stages of ripple−carry binary counter. The device
advances the count on the negative−going edge of the clock pulse.
Applications include time delay circuits, counter controls, and
frequency−dividing circuits.
Features
• Fully Static Operation
• 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
• Buffered Outputs Available from stages 1 and 4 thru 14
• Common Reset Line
• Pin−for−Pin Replacement for CD4020B
• These are Pb−Free Devices

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

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, V

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V
