Introduction

The CD405X series analog switches are digitally-controlled multiplexing and demultiplexing analog switches featuring low on-resistance and extremely low off-state leakage current. The digital control signal voltage range is 4.5V to 18V, capable of handling analog signals with a peak-to-peak amplitude of up to 18V. For example, with VDD = +5V, VSS = 0V, and VEE = -13.5V, a 0V to 5V digital signal can control analog signals ranging from -13.5V to 4.5V. Throughout the entire supply voltage range of VDD-VSS and VDD-VEE, this switch series exhibits extremely low quiescent power consumption. The CD4052 is a differential 4-channel multiplexer/demultiplexer featuring two binary control inputs (A and B) and an INH input for each 4-to-1 switch group. The two binary signals select any one of the four analog channels to be turned on. When a logic "1" is applied to the INH input, all channels of both 4-to-1 switch groups are disabled; when a logic "0" is applied, all channels are enabled.

Features

• Wide voltage range for digital control and analog signal transmission: 4.5V ~ 18V for digital signals, up to 18V for analog signals.
• Low on-resistance: 100Ω at VDD-VEE = 15V with signal greater than 15Vpp.
• Very low quiescent power dissipation.
• High off-state resistance.
• Logic level shifting via 4.5V ~ 18V digital address signals to switch 18Vpp analog signals.
• Built-in binary address decoder.
