描述 Description

The NX3DV42 is a double-pole double-throw analog switch suitable for use as an analogor digital multiplexer/demultiplexer. Its wide bandwidth and low bit-to-bit skew allows theNX3DV42 to pass high-speed differential signals with good signal integrity. Its highchannel to channel crosstalk rejection results in minimal noise interference. Thebandwidth is wide enough to pass high-speed USB 2.0 differential signals (480 Mb/s). Itconsist of two switches, each with two independent input/outputs (HSDn+ and HSDn-)and a common input/output (D+ or D-). One digital inputs (S) is used to select the switchposition. When pin OE is HIGH, the switches are turned off. Schmitt trigger action at theselect input (S) and enable input (OE) makes the circuit tolerant to slower input rise andfall times across the entire VCC range from 3.0 V to 4.3 V.
