| Description & Applications | Decade Counter / Divider Description The HD74HC4017 is a 5-stage divide-by-10 Johnson counter with ten decoded outputs and a carry-out bit. High-speed operation and spike-free outputs are obtained by use of the Johnson decade counter configuration. The ten decoded outputs are normally low and go high only at their respective decimal time periods. A high signal on Reset R asynchronously clears the decade counter and sets the carry output and Y0 high. With CE low, the count is advanced on a low-to-high transition at C input. Alternatively, if C is high, the count is advanced on a high-to-low transition at CE. Each decoded output remains high for one full clock cycle. The carry output is high while Q0, Q1, Q2, Q3 or Q4 is high, then is low while Q5, Q6, Q7, Q8 or Q9 is high. Features • High Speed Operation • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) • Ordering Information |
| 描述与应用 | 十进制计数器/除法器 描述 在该HD74HC4017是一个5级分，约翰逊1010解码输出和进位位计数器。快速 操作和穗自由输出的约翰逊十进制计数器配置的使用通过以下方式获得。 10个解码输出通常是低高走，只能在各自的十进制时间周期。上高信号 复位R，异步清零十进制计数器，并设置进位输出Y0高。 CE低，计数 先进的C输入由低到高的跳变。另外，如果C为高时，计数上的高到低的前进 在CE过渡。每个解码输出仍然是一个完整的时钟周期。进位输出为高，而Q0，Q1，Q2， Q3或Q4高，而Q5，Q6，Q7，Q8或Q9是高是低。 •高速运行 •高输出电流：扇出的10输入通道荷载 •宽工作电压：VCC=2到6 V •低输入电流：最大1μA •低静态电源电流：ICC（静态）= 4μA最大（大= 25°C） •订购信息 |
