The NLAS4066DTR2 is an analog switch and multiplexer/demultiplexer solution featuring low on-resistance and good linearity. It is characterized by low leakage, low voltage noise, and low-power consumption. Applications include consumer, industrial, and automotive audio switching, multiplexing/demultiplexing, data multiplexing/demultiplexing, and input and output buffering.

The NLAS4066DTR2 can be used as an analog switch to connect or disconnect two audio or video sources, and as a multiplexer/demultiplexer, to select and switch between multiple audio or video signals. When used as a multiplexer, the NLAS4066DTR2 can multiplex up to four signals with two control signals, making it useful for audio, video, and mixed-signal applications. The device comprises two independent switches, each with two control signals, which allow for heightened flexibility in audio/video switching.

It is also suitable for high-precision applications requiring low-noise operation and low on-resistance. The NLAS4066DTR2 utilizes on-chip precision trimmed resistors and delivers a typical on-resistance of 2.1 Ω, which reduces power dissipation and helps reduce noise and crosstalk. The device’s low on-resistance also helps ensure quick switching and low distortion in the audio/video signals.

The NLAS4066DTR2 is configured by two control inputs A and B, which allows it to be used as an analog switch, multiplexer/demultiplexer, or switch in both directions. When used as an analog switch, the outputs of the two sections (A1 and A2) are shorted together. At that time, the two control inputs (A and B) must be driven by a logic level rail-to-rail signal, typically a digital logic signal. When controlling an analog switch, the logic levels must be high (1) or low (0) and should maintain a low-impedance connection to the logic rail.

When used as a multiplexer (MUX) or demultiplexer (DEMUX), the two sections are configured by two control inputs. As a MUX, it is used to select one of four possible inputs, and as a DEMUX, it is used to select one of two outputs from a single input. In this configuration, the two control inputs should be driven from a logic level rail-to-rail signal and must be low (0) or high (1).

The NLAS4066DTR2 features low-voltage noise (8 nV/√Hz), low power consumption (0.09 mW/channel), and rail-to-rail switching (rail-to-rail on both inputs and outputs). Additionally, it has ESD ratings of ±8 kV and is available in SOIC-8, TSSOP-8, and PDIP-8 packages.

In summary, the NLAS4066DTR2 is an analog switch and multiplexer/demultiplexer solution offering low on-resistance and good linearity, low-voltage noise, low power consumption, rail-to-rail switching, and ESD protection. Applications include consumer, industrial, and automotive audio switching, multiplexing/demultiplexing, data multiplexing/demultiplexing, and input and output buffering.
