CD74HC4020 Overview
The ’HC4020 and ’HCT4020 are 14-stage ripple-carry binary counters. All counter stages are controller/ peripheral flip- flops. The state of the stage advances one count on the negative clock transition of each input pulse;.
CD74HC4020 Key Features
- Fully static operation
- Buffered inputs
- mon reset
- Negative edge clocking
- Fanout (over temperature range)
- Standard outputs: 10 LSTTL loads
- Bus driver outputs: 15 LSTTL loads
- Wide operating temperature range: -55℃ to 125℃
- Balanced propagation delay and transition times
- Significant power reduction pared to LSTTL Logic ICs
