Quad SPDT analog switch in 20-TSSOP
Each of the four independent switches handles rail-to-rail analog signals with a maximum on-resistance of 35 ohms. Switching is fast — 130 ns turn-on, 75 ns turn-off — and the charge injection is a low 5 pC, which matters when you are multiplexing a sample-and-hold or a precision DAC reference. The part runs on a single supply from 2.7 V to 15 V, or on dual supplies from ±2.7 V to ±8 V, giving flexibility for bipolar signal chains. The -88 dB crosstalk at 1 MHz tells you the channels stay isolated well into the low-MHz range, so it fits audio routing, data acquisition front-ends, and ATE pin electronics where channel bleed cannot be tolerated.
Crosstalk and isolation — what -88 dB at 1 MHz buys you
The -88 dB crosstalk at 1 MHz means feedthrough into an off channel is 88 dB down.
