14位异步二进制计数器 14-BIT ASYNCHRONOUS BINARY COUNTERS
description/ordering information
The ’HC4020 devices are 14-stage binary ripple-carry counters that advance on the negative-going edge of the clock pulse. The counters are reset to zero all outputs low independently of the clock CLK input when the clear CLR input goes high.
● Wide Operating Voltage Range of 2 V to 6 V
● Outputs Can Drive Up To 10 LSTTL Loads
● Low Power Consumption, 80-µA Max ICC
● Typical tpd = 12 ns
● ±4-mA Output Drive at 5 V
● Low Input Current of 1 µA Max
