14-Stage Binary Ripple Counter IC - 74HC4020
The 74HC Series 74HC4020 is a 16 Pin 14-Stage Binary Ripple Counter IC having 2V to 6V Operating Voltage range with a 1uA low input current. It has a clock input (CP), an overriding asynchronous master reset input (MR), and 12 buffered parallel outputs (Q0, and Q3 to Q13). The counter advances on the HIGH-to-LOW transition of CP.
A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
