The CD405xB-Q1 line of multiplexers and demultiplexers can accept a wide range of digital and analog signal levels. Digital signals range from 3 V to 20 V, and analog signals are accepted at levels ≤ 20 V. The devices have low ON resistance, typically 125 Ω over 15 V_P-P signal input range for V_DD – V_EE = 18 V. This feature allows for very little signal loss through the switch. Matched switch characteristics are typically r_ON = 5 Ω for V_DD – V_EE = 15 V.

The CD405xB-Q1 devices also have high OFF resistance, which keeps from wasting power when the switch is in the OFF position, with typical channel leakage of ±100 pA at V_DD – V_EE = 18 V. Very low quiescent power dissipation under all digital-control input and supply conditions, typically 0.2 µW at V_DD – V_SS = V_DD – V_EE = 10 V keeps power consumption total very low. All devices have been 100% tested for quiescent current at 20 V with maximum input current of 1 µA at 18 V over the full package temperature range, and only 100 nA at 18 V and 25°C.

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). Binary address decoding on chip makes channel selection easy. When channels are changed, a break-before-make system eliminates channel overlap.
