14-Stage Binary Counter February 1998 -Revised October 2003 Features Description Fully Static Operation The ’HC4020 and ’HCT4020 are 14-stage ripple-carry
binary counters. All counter stages are master-slave flipflops. The state of the stage advances one count on the
negative clock transition of each input pulse; a high voltage
level on the MR line resets all counters to their zero state. All
inputs and outputs are buffered. Buffered Inputs Common Reset Negative Edge Clocking Fanout (Over Temperature Range) Ordering Information -Standard Outputs . 10 LSTTL Loads
-Bus Driver Outputs . 15 LSTTL Loads PART NUMBER Wide Operating Temperature Range . -55oC to 125oC TEMP. RANGE
