1 Features

• Wide range of digital and analog signal levels:

– Digital: 3V to 20V

– Analog: ≤ 20VP-P

• Single supply range : 3V to 20V (performance

degrades for VDD < 3V)

• Dual Supply range: ± 3V to ± 10V

• Low ON resistance, 125Ω (typical) over input

range for VDD = 15V

• Low channel leakage of ±10pA (typical) at VDD =

15V

• Low quiescent power dissipation : 0.2μW (typical)

• Break-before-make switching eliminates channel

overlap

• Bidirectional signal path

• ESD protection HBM: 3000V, CDM: 2000V

• Pin compatible with industry standard 4051 muxes

2 Applications

• Televisions

• Appliances

• Consumer audio

• Programmable logic circuits

• Sensors

3 Description

The CD405xB analog multiplexers and demultiplexers

are digitally-controlled analog switches having low ON

impedance and very low OFF leakage current. These

multiplexer circuits dissipate extremely low quiescent

power over the full VDD – VSS and VDD – VEE supplyvoltage

ranges, independent of the logic state of the

control signals.
