CD4066B CMOS Quad Bilateral Switch
Features
The CD4066B device is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin compatible with the CD4016B device, but exhibits a much lower on-state resistance. In addition, the on-state resistance is relatively constant over the full signalinput range.
The CD4066B device consists of four bilateral switches, each with independent controls. Both the p and the n devices in a given switch are biased on or off simultaneously by the control signal. As shown in Figure 17, the well of the n-channel device on each
switch is tied to either the input (when the switch is on) or to VSS (when the switch is off). This configuration eliminates the variation of the switchtransistor threshold voltage with input signal and, thus, keeps the on-state resistance low over the full operating-signal range.
The advantages over single-channel switches include peak input-signal voltage swings equal to the full supply voltage and more constant on-state impedance over the input-signal range. However, for sample-and-hold applications, the CD4016B device is recommended.
CD4066B CMOS 四路雙邊開關
特徵
CD4066B 器件是一個四路雙向開關，用於模擬或數字信號的傳輸或多路復用。它與 CD4016B 器件引腳對引腳兼容，但導通電阻要低得多。此外，通態電阻在整個信號輸入範圍內相對恆定。
CD4066B 設備由四個雙邊開關組成，每個開關都有獨立的控制。給定開關中的 p 和 n 器件都由控制信號同時偏置開或關。如圖 17 所示，每個 n 溝道器件的阱
開關連接到輸入（當開關打開時）或 VSS（當開關關閉時）。這種配置消除了開關晶體管閾值電壓隨輸入信號的變化，因此在整個工作信號範圍內保持低通態電阻。
與單通道開關相比，其優勢包括峰值輸入信號電壓擺幅等於全電源電壓，以及在輸入信號範圍內更恆定的導通狀態阻抗。但是，對於採樣保持應用，建議使用 CD4016B 器件。
