MC14020B
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.
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

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
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
v vhigh–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.
