CD74HC4020M

The CD74HC4020M is a 14-stage ripple-carry binary counter. All the counter stages are flip-flops. 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.

• Fully static operation

• Balanced propagation delay and transition times
• Significant power reduction compared to LSTTL logic ICs
• High noise immunity
• Direct LSTTL input logic compatibility
• CMOS input compatibility
• 10 LSTTL load standard outputs
• 15 LSTTL load bus driver outputs
• Green product and no Sb/Br
