SCHS047H – AUGUST 1998 – REVISED APRIL 2015
CD405xB CMOS Single 8-Channel Analog Multiplexer/Demultiplexer
With Logic-Level Conversion
1 Features
•1 Wide Range of Digital and Analog Signal Levels
– Digital: 3 V to 20 V
– Analog: ≤20 V_P-P
• Low ON Resistance,125 Ω (Typical) Over 15 V_P-P
Signal Input Range for V_DD – V_EE = 18 V
• High OFF Resistance, Channel Leakage of ±100
pA (Typical) at V_DD – V_EE = 18 V
• Logic-Level Conversion for Digital Addressing
Signals of 3 V to 20 V (V_DD – V_SS = 3 V to 20 V)
to Switch Analog Signals to 20 V_P-P (V_DD – V_EE =
20 V) Matched Switch Characteristics, r_ON = 5 Ω
(Typical) for V_DD – V_EE = 15 V Very Low Quiescent
Power Dissipation Under All Digital-Control Input
and Supply Conditions, 0.2 µW (Typical) at V_DD –
V_SS = V_DD – V_EE = 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
2 Applications
• Analog and Digital Multiplexing and
Demultiplexing
• A/D and D/A Conversion
• Signal Gating

• Televisions
• Appliances
• Consumer Audio
• Programmable Logic Circuits
• Sensors
3 Description
The CD405xB analog multiplexers and demuliplexers
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 V_DD – V_SS and V_DD –
V_EE supply-voltage ranges, independent of the logic
state of the control signals.
