8.3 Feature Description
The CDx4HCx405x line of multiplexers and demultiplexers can accept a wide range of analog signal levels from
–5 to +5 V. They have low ON resistance, typically 70-Ω for V_CC – V_EE = 4.5 V and 40-Ω for V_C – V_EE = 4.5 V,
which allows for very little signal loss through the switch.
Binary address decoding on chip makes channel selection easy. When channels are changed, a break-before-
make system eliminates channel overlap.
