Automotive-Compliant Level Shifters from Diodes Incorporated Provide High-Speed, Flexible, and Easy-to-Use Logic Translation

Diodes Incorporated (Nasdaq: DIOD) today announced two flexible, high-speed automotive-compliant voltage translators for use in environments with ambient temperatures up to +125°C. The PI4ULS5V108Q and PI4ULS5V202Q are designed for use in advanced driver-assistance systems (ADAS), infotainment, and telematics equipment.

Both devices are compatible with either push-pull or open-drain connections, delivering the convenience of a single part number to address multiple applications. In addition, bidirectional flexibility with automatic direction sensing simplifies level shifting between bus interfaces, such as SMBus, PMBus, or I2C devices, by eliminating any requirement for a direction-control signal.

The 8-channel PI4ULS5V108Q performs up-translation at up to 100MHz and down-translation at over 100MHz, delivering responsive performance for use in high data-rate interfaces. Designers can ensure fast exchanges across SPI or other interfaces, with no limitation due to level shifting. This enables data transfers between system-on-chip (SoC) and peripheral components to be executed with optimum efficiency.

The PI4ULS5V202Q is a 2-channel translator with internal 10kΩ pull-up resistors, allowing direct connection to interfaces with open-drain topology, such as I2C ports. The large maximum voltage-translation range of 1.2V to 5.5V provides flexibility to work with a wide variety of I2C chips and circuit designs. The PI4ULS5V202Q features fast rise and fall times, due to high-speed one-shot detectors at the IC inputs and is able to support data rates of up to 20Mbps.

Both devices are AEC-Q100 grade 1 qualified, PPAP capable, and in production at IATF 16949 certified sites.

The PI4ULS5V108Q and PI4ULS5V202Q are available now in the TSSOP-20 and MSOP-8 packages, respectively.
