Nexperia has launched the NMUX27518-Q100 and NMUX27518 multiplexers for automotive applications. The NMUX27518-Q100, a bidirectional six-channel 2:1 multiplexer, enables memory expansion via a quad SPI (qSPI) port in safety-critical in-vehicle applications such as the advanced driver assistance systems (ADAS) domain controller, the automotive head unit, and telematics control units. A standard version, the NMUX27518 can be used for audio and video signal routing in consumer and enterprise applications including notebooks, tablets, motherboards, and rack servers.

The new devices are the industry’s first multiplexers operating from an extended 1.08-V to 3.63-V voltage range, according to Nexperia. They can accommodate digital and analog signals and transmit signals up to the supply voltage level (VCC) in either direction.
Two control pins simultaneously control three 1:2 multiplexers and are compatible with 1.8-V logic thresholds. They are also backward compatible with 2.5-V and 3.3-V logic thresholds, while unused outputs can be placed in a high-impedance state.
The 500-MHz bandwidth of these switches is twice that of similar competing devices to better preserve fast rise and fall times, Nexperia said. In addition, low port skew (150 ps typical) between channels helps with optimizing setup and hold times. Both devices operate at temperatures ranging between -40°C and 125°C.
The NMUX27518 and NMUX27518-Q100 are available now. They are housed in a plastic thin shrink small outline package with 24 leads (TSSOP24) and a body width of 4.4 mm. They are also available in a plastic thermal enhanced leadless very thin quad flat package with 24 terminals (HWQFN24), measuring 4 × 4 × 0.75 mm with a 0.5-mm pitch.
