Nexperia introduced a new series of 4- and 8-channel analog switches designed to monitor and protect 1.8 V electronic systems. This series of multiplexers includes AEC-Q100 qualified variants intended for use in automotive applications as well as standard versions suitable for a broader range of consumer and industrial applications including sensor monitoring and diagnostics, enterprise computing and domestic appliances.
When using analog switches, designers commonly require additional voltage translators because the control circuitry cannot operate from the voltage level used to supply power to the switch. By contrast, the control pins in the NMUX1308 and NMUX1309 switches operate independently of their power supply voltage range, negating the need to use additional components to perform level-shifting and thus saving board-space and reducing costs.
These devices integrate injection current control circuitry, limiting output voltage shifts on the active channel to under 5 mV when an overvoltage event happens on disabled signal channels (more info).
