AEC-Q100 qualified multiplexers deliver superior reliability in automotive applications

Nexperia has announced the latest addition to its portfolio of AEC-Q100 (grade 1) qualified devices that deliver the reliability demanded for automotive applications. The NMUX27518-Q100 is a bidirectional six-channel 2:1 multiplexer, making it excellent for helping memory expansion via a qSPI port in safety-critical in-vehicle applications like the ADAS domain controller, the automotive head unit and telematics control units. The device is a standard version of this switch that can also be employed for audio and video signal routing in consumer and enterprise applications like notebooks, tablets, motherboards and rack servers.

The NMUX27518 and NMUX27518-Q100 are the industry’s first multiplexers to operate from an extended 1.08V to 3.63V voltage range. Also, they can accommodate digital and analogue signals and can transmit signals up to the supply VCC in either direction. Two control pins, which simultaneously control three 1:2 multiplexers, are compatible with 1.8V logic thresholds and are also backwards compatible with 2.5V and 3.3V logic thresholds, while unused outputs can be placed in a high-impedance state. The 500MHz bandwidth of these switches is twice that of similar competing devices to better preserve fast rise and fall times. In addition, low port skew (150ps typical) between channels helps with optimising setup and hold times.

“At Nexperia, we are extremely proud to deliver products that set new benchmarks for quality and performance. The NMUX27518-Q100, qualified to AEC-Q100 Grade 1, exemplifies our commitment to going beyond standard requirements to ensure the highest levels of quality and reliability. This differentiation provides the automotive industry with the dependable performance it demands, while also offering the bandwidth and versatility needed to support the next generation of safety-critical and high-performance applications,” said Irene Deng, general manager for IC Solutions division at Nexperia.

The NMUX27518 and NMUX27518-Q100 come in a plastic thin shrink small outline package with 24 leads (TSSOP24) that has a body width of only 4.4mm. They are also available in a plastic thermal enhanced leadless very thin quad flat package with 24 terminals (HWQFN24) that have 0.5mm pitch and 4mm × 4mm × 0.75mm body dimensions. Both devices can operate at temperatures ranging between -40C and +125C.
