Multiplexer, 8-CH, 3 ... 20 V, SO-16

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.

Features
- wide range of digital and analog signal levels:
- Digital: 3 V to 20 V
- Analog: = 20 VP-P

- low ON resistance, 125 ? (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 20V) to switch analog signals to 20 VP-P (VDD - VEE = 20 V) matched switch characteristics, rON = 5 ? (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
