Description & Applications DUAL BINARY COUNTER DESCRIPTION The M74HC393 is an high speed CMOS DUAL BINARY COUNTER fabricated with silicon gate C2 MOS technology. This counter circuit contains independent ripple carry counters and two 4-bit ripple carry binary counters, which can be cascaded to create a single divide by 256 counter. Each 4-bit counter is incremented on the high to low transition (negative edge) of the clock input, and each has an independent clear input. When CLEAR is set to low, all four bits of each counte rare set to a low level. This enables count truncation and allows the implementation of divide by N counter configurations. All inputs are equipped with protection circuits against static discharge and transient excess voltage. HIGH SPEED : fMAX = 79 MHz (TYP.) at VCC = 6V LOW POWER DISSIPATION: ICC =4μA(MAX.) at TA=25°C HIGH NOISE IMMUNITY: VNIH = VNIL= 28 % VCC (MIN.) YMMETRICAL OUTPUT IMPEDANCE: IOH| = IOL= 4mA (MIN) BALANCED PROPAGATION DELAYS: PLH ? tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 393
描述与应用 双二进制计数器 说明 M74HC393是一个高速CMOS双 二进制计数器制作与硅栅 C2 MOS技术。 此计数器电路包含独立的波进位计数器和两个4位波进位二进制计数器,可以级联,以建立一个单一的256分频计数器。 每4位计数器在高向低过渡的时钟输入(下降沿),每个人都有一个独立的明确的输入。何时 清楚的是设置为低,的所有4位每逆流罕见的集到一个较低的水平。这使计数截断和N计数器的配置,允许执行的鸿沟。 所有输入都配有保护电路 防止静电放电和瞬态过电压。 FMAX =79 MHz(典型值)在VCC =6V n低功耗: ICC=4μA(最大值)在TA= 25°C N高抗干扰性: VNIH= VNIL VCC=28%(最小) YMMETRICAL输出阻抗: IOH|:IOL=4毫安(MIN) 平衡传输时延: PLH?TPHL 宽工作电压范围: VCC(OPR)=2V到6V 引脚与功能兼容 74系列393
