PI4ULS5V108Q and PI4ULS5V202Q – 8-bit and 2-bit Level Shifter for Automotive Infotainment Applications

Diode Incorporated has announced the release of PI4ULS5V108Q & PI4ULS5V202Q, two high speed, flexible and easy to use automotive compliant voltage translators for use in ambient temperature up to 125°C. Both the device is compatible with either push-pull or open-drain connections, which provides the convenience of using a single part number to address multiple applications. The combination of bidirectional flexibility and automatic direction sensing simplifies level shifting between bus interfaces like SMBus, PMBus, or I2C devices by eliminating any requirement for a direction-control signal.

The 8 channel PI4ULS5V108Q can perform up-translation at up to 100MHz and down-translation at over 100MHz, it can deliver responsive performance for use in high data rate interfaces. The data transfer between system-on-chip (SoC) and peripheral components can be executed with optimum efficiency due to faster exchanges across SPI or other interfaces with no limitation due to level shifting.

Features of PI4ULS5V108Q:

• Low Standby Current
• Supports Up to 100MHz Up Translation and greater than 100MHz Down Translation 
• Allow Bidirectional Voltage-Level Translation Between
  • 0.95V - 1.8/2.5/3.3/5V
  • 1.2V - 1.8/2.5/3.3/5V
  • 1.8V - 2.5/3.3/5V
  • 2.5V - 3.3/5V
  • 3.3V - 5V
• 5V Tolerance I/O Port to Support TTL
• Low Ron Provides Less Signal Distortion

The 2 channel PI4ULS5V202Q has the internal 10KΩ pull up resistors that can allow direct connection to interface with an open-drain topology such as I2C ports. The translator can be used in a wide variety of I2C chips and circuit designs due to its large maximum voltage translation range of 1.2V to 5.5V. The PI4ULS5V202Q features fast rise and fall time due to high-speed one-shot detectors at the IC inputs and is able to support data rates of up to 20Mbps.

Features of PI4ULS5V202Q:

• High-speed with 2 Mb/s Data Rate for push-pull application
• High-speed with 2 Mb/s Data Rate for open-drain application
• 1.2V to 5.5V on A Port and 1.2V to 5.5V on B port
• No Direction-Control signal needed
• Low bit-to-bit skew
• Non-preferential power-up sequencing
• ESD protection exceeds 8KV HBM per JESD22-A114
• Integrated 10KΩ pull-up resistors

Both devices are designed for use in advanced driver-assistance systems (ADAS), infotainment, and telematics equipment. The PI4ULS5V108Q and PI4ULS5V202Q are available now in the TSSOP-20 and MSOP-8 packages, respectively, they are AEC-Q100 grade 1 qualified, PPAP capable, and in production at IATF 16949 certified sites.
