Package Characteristics

*The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-outputcontinuous voltage rating. For the continuous voltage rating refer to the VDE 0884 Insulation Characteristics Table (if applicable),your equipment level safety specification or HP Application Note 1074 entitled “Optocoupler Input-Output Endurance Voltage,”publication number 5963-2203E.

Notes:

1. Each channel.

2. Derate total package power dissipation, PT, linearly above 70°C free-air temperature at a rate of 4.5 mW/°C.3. Duration of output short circuit time should not exceed 10 ms.

4. For single devices, input capacitance is measured between pin 2 and pin 3.

5. Device considered a two-terminal device: pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 shorted together.

6. The tPLH propagation delay is measured from the 50% point on the leading edge of the input pulse to the 1.3 V point on theleading edge of the output pulse. The tPHL propagation delay is measured from the 50% point on the trailing edge of the inputpulse to the 1.3 V point on the trailing edge of the output pulse.

7. CMH is the maximum slew rate of the common mode voltage that can be sustained with the output voltage in the logic high state,VO > 2.0 V. CML is the maximum slew rate of the common mode voltage that can be sustained with the output voltage in the logiclow state, VO < 0.8 V.

8. For HCPL-2202/12, VO is on pin 6.

9. Use of a 0.1 μF bypass capacitor connected between pins 5 and 8 is recommended.

10. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥3000 V rms for one second

(leakage detection current limit, II-O ≤5 μA). This test is performed before the 100% production test for partial discharge (Methodb) shown in the VDE 0884 Insulation Characteristics Table, if applicable.

11. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥6000 V rms for one second

(leakage detection current limit, II-O ≤5 μA). This test is performed before the 100% production test for partial discharge (Methodb) shown in the VDE 0884 Insulation Characteristics Table.

12. For HCPL-2231/32 only. Measured between pins 1 and 2, shorted together, and pins 3 and 4, shorted together.

CD4066中文资料

CD4066 的引脚功能下图所示。(www.61k.com］每个封装内部有4 个独立的模拟开关，每个模拟开关有输入、输出、控制三个端子，其中输入端和输出端可互换。当控制端加高电平时，开关导通；当控制端加低电平时开关截止。模拟开关导通时，导通电阻为几十欧姆；模拟开关截止时，呈现很高的阻抗，可以看成为开路。模拟开关可传输数字信号和模拟信号，可传输的模拟信号的上限频率为40MHz。各开关间的串扰很小，典型值为－50dB。

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。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端，开关可以相互独立地开断，互补影响。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。CD4066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。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。
