1 Features

? Wide range of digital and analog signal levels:

– Digital: 3 V to 20 V

– Analog: ≤ 20 VP-P

? Low ON resistance, 125 Ω (typical) over 15 VP-P

signal input range for VDD – VEE = 18 V

? High OFF resistance, channel leakage of

±100 pA (typical) at VDD – VEE = 18 V

? Logic-level conversion for digital addressing

signals of 3 V to 20 V (VDD – VSS = 3 V to 20

V) to switch analog signals to 20 VP-P (VDD – VEE

= 20 V) matched switch characteristics, rON = 5 Ω

(typical) for VDD – VEE = 15 V very low quiescent

power dissipation under all digital-control input and

supply conditions, 0.2 μW (typical) at

VDD – VSS = VDD – VEE = 10 V

? Binary address decoding on chip

? 5 V, 10 V, and 15 V parametric ratings

? 100 tested for quiescent current at 20 V

? Maximum input current of 1 μA at 18 V over full

package temperature range, 100 nA at 18 V and

25°C

? Break-before-make switching eliminates channel

overlap

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.
