CD4066 中文资料： CD4066 是四双向模拟开关，主要用作模拟或数字信号的多路传输引出端排列与 CC4016 一致，但具有比较低的导通阻抗另外，导通阻抗在整个输入信号范围内基本不变CD4066 由四个相互独立的双向开关组成，每个开关有一个控制信号，开关中的 p 和n 器件在控制信号作用下同时开关这种结构消除了开关晶体管阈值电压随输入信号的变化，因此在整个工作信号范围内导通阻抗比较低与单通道开关相比，具有输入信号峰值电压范围等于电源电压以及在输入信号范围内导通阻抗比较稳定等优点但若应用于采保电路，仍推荐CD4016当模拟开关的电源电压采用双电源时，例如 =﹢5V， =﹣5V（均对地 0V 而言），则输入电压对称于 0V 的正、负信号电压（﹢ 5V～﹣5V）均能传输这时要求控制信号 C=“1”为+5V，C=“0” 为-5V，否则只能传输正极性的信号电压CD4066 引脚功能图 内部方框图Absolute Maximum Ratings 绝对最大额定值： Supply Voltage 电源电压(VDD) −0.5V to +18VInput Voltage 输入电压 (VIN) −0.5V to VCC+0.5VStorage Temperature Range 储存温度范围 (TS) −65℃ to +150℃Power Dissipation 功耗 (PD)Dual-In-Line 普通双列封装 700 mW Small Outline 小外形封装 500 mW Lead Temperature 焊接温度(TL) Soldering, 10 seconds)（焊接 10 秒） 300℃ Recommended Operating Conditions 建议操作条件： Supply Voltage 电源电压(VDD) 3V to 15VInput Voltage 输入电压 (VIN) 0V to VDDOperating Temperature Range 工作温度范围 (TA) −55℃ to +125℃ DC Electrical Characteristics 直流电气特性： −55℃ +25℃ +125℃ Symbol 符号 Parameter 参数 Conditions 条件 最小 最大 最小 典型 最大 最小 最大Units 单位 VDD = 5V 0.25 0.01 0.25 7.5 VDD = 10V 0.5 0.01 0.5 15 IDD Quiescent Device Current 静态电流 VDD = 15V 1.0 0.01 1.0 30 μA SIGNAL INPUTS AND OUTPUTS RL = 10 kΩ to (VDD − VSS/2) VC = VDD, VSS to VDD VDD = 5V 800 270 1050 1300 RON “ON” Resistance VDD = 10V 310 120 400 550 Ω VDD = 15V 200 80 240 320 RL = 10kΩ to (VDD − VSS/2) VCC = VDD, VIS = VSS to VDD VDD = 10V 10 ΔRON Δ“ON” Resistance Between Any 2 of 4 Switches VDD = 15V 5 Ω IIS Input or Output Leakage Switch “OFF” VC = 0 ±50 ±0.1 ±50 ±500 nACONTROL INPUTS VIS = V SS and VDD VOS = V DD and VSS IIS = ± 10μA VDD = 5V 1.5 2.25 1.5 1.5 VDD = 10V 3.0 4.5 3.0 3.0 VILC LOW Level Input Voltage 输入低电平电压 VDD = 15V 4.0 6.75 4.0 4.0 V VDD = 5V 3.5 3.5 2.75 3.5 VDD=10V (Note 7) 7.0 7.0 5.5 7.0 VIHC HIGH Level Input Voltage 输入高电平电压 VDD = 15V 11.0 11.0 8.25 11.0 V −0.1 −10−5 −0.1 −0.1 IIN Input Current 输入电流 VDD−VSS = 15V VDD≥VIS≥VSS VDD≥VC≥VSS 0.1 10−5 0.1 0.1μA AC Electrical Characteristics 交流电气特性： Symbol 符号 Parameter 参数 Conditions 条件 最小 典型 最大 Units 单位 VC = VDD, CL = 50 pF, (Figure 1)RL = 200kVDD = 5V 25 55 VDD = 10V 15 35 tPHL, tPLHPropagation Delay Time Signal Input to Signal Output 信号输入到信号输出传递延迟时间VDD = 15V 10 25 nsRL = 1.0kΩ, CL = 50pF, (Figure 2, Figure 3) VDD = 5V 125VDD = 10V 60 tPZH, tPZLPropagation Delay Time Control Input to Signal Output High Impedance to Logical LevelVDD = 15V 50 nsRL = 1.0kΩ, CL = 50pF VDD = 5V 125VDD = 10V 60 VDD = 15V 50 nsVC = VDD = 5V, VSS = −5V RL = 10 kΩ, VIS = 5Vp-p, f= 1 kHz, (Figure 4)0.1 %tPHZ, tPLZPropagation Delay Time Control Input to Signal Output Logical Level to High Impedance Sine Wave Distortion Frequency Response-Switch “ON” (Frequency at −3 dB) VC = VDD = 5V, VSS = −5V, RL = 1 kΩ, VIS = 5Vp-p, 20 Log10 VOS/VOS (1 kHz)−dB,(Figure 4)40 MHz VDD = 5.0V, VCC = VSS = −5.0V, RL = 1 kΩ, VIS = 5.0Vp-p, 20 Log10, VOS/VIS = −50 dB, (Figure 4)1.25 VDD=VC(A) =5.0V; VSS = VC(B) = 5.0V, RL1kΩ, VIS(A) = 5.0Vp-p, 20 Log10, VOS(B)/VIS(A) = −50dB (Figure 5)0.9 MHzVDD =10V,RL=10kΩ, RIN=1.0kΩ,VCC=10V Square Wave, CL =50pF(Figure 6)150 mVp-pRL=1.0kΩ, CL=50pF, (Figure 7)VOS(f) = ½ VOS(1.0 kHz)VDD = 5.0V 6.0 VDD = 10V 8.0 Feedthrough — Switch “OFF” (Frequency at −50 dB) Crosstalk Between Any Two Switches (Frequency at −50 dB) Crosstalk; Control Input to Signal Output Maximum Control InputVDD = 15V 8.5 MHzCIS Signal Input Capacitance 信号输入电容 8.0 pFCOS Signal Output Capacitance 信号输出电容 VDD = 10V 8.0 pFCIOS Feedthrough Capacitance 馈电容 VC = 0V 0.5 pFCIN Control Input Capacitance 控制输入电容 5.0 7.5 pF 图 1 CD4066 是四双向模拟开关驱动继电器应用电路CD4066 是四双向模拟开关，集成块 SCR1～SCR4 为控制端，用于控制四双向模拟开关的通断。

当 SCR1 接高电平时，集成块①、②脚导通，＋12V→K1→集成块①、②脚→电源负极使K1 吸合；反之当 SCR1 输入低电平时，集成块①、②脚开路，K1 失电释放，SCR2 ～SCR4输入高电平或低电平时状态与 SCR1 相同。
