MC14020B
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
* Maximum Ratings are those values beyond which damage to the device may occur.
Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/ C From 65 C To 125 C
Ceramic “L” Packages: – 12 mW/ C From 100 C To 125 C
