M74HC4017B1R集成电路（IC）的计数器除法器规格书PDF中文资料

M74HC4017B1R属于集成电路（IC）的计数器除法器。由意法半导体集团制造生产的M74HC4017B1R计数器，除法器计数器和除法器 IC 是数字逻辑器件，可对输入发生的逻辑转换进行计数，然后使用多个并行输出重新发送累加的计数，和/或生成单个输出信号转换，从而对应用某些整数数量输入信号转换进行响应。除了简单的事件计数，它们还可用于各种频率合成应用。

DESCRIPTION

The M74HC4017 is an high speed CMOS DECADE COUNTER/DIVIDER fabricated with silicon gate C2MOS technology.

The M74HC4017 is a 5-stage Johnson counter with 10 decoded outputs. Each of the decoded outputs is normally low and sequentially goes high on the low to high transition of the clock input.

■ HIGH SPEED : tPD = 21 ns (TYP.) at VCC = 6V

■ LOW POWER DISSIPATION: ICC =4µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.)

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4017
