Product Overview
The device operates from a recommended VDD range of 1.08 to 5.5 V. The signal path range for Sx/Dx pins is 0 V to VDD, while SELx logic control inputs are specified from 0 to 5.5 V and are 1.8 V logic compatible. At VDD=5 V, on-resistance is 2 ohm typical and 4 ohm maximum at 25 °C, with 0.13 ohm typical channel-to-channel matching and 0.85 ohm typical flatness under the stated 10 mA test condition.
Package options include PW TSSOP, 16-pin and RSV UQFN/QFN, 16-pin. Thermal data lists 124.7 °C/W junction-to-ambient resistance for PW TSSOP and 146.8 °C/W for RSV QFN. The operating ambient range is -40 to 125 °C, with storage temperature from -65 to 150 °C and a 150 °C junction temperature rating.
The switch is suited to low-voltage analog and digital signal routing where low leakage, low charge injection, bidirectional paths, active-low logic, and independent channel selection are required.
