Eight-channel level shifter is bi-directional for inter-IC comms

The bi-directional PI4ULS5V108 is an eight-channel, high speed level shifter designed by Diodes for inter-IC communications between devices operating on different voltage supply rails. It targets applications such as PCs, servers, networking, telecomms and consumer electronics.

The PI4ULS5V108 supports up to 100MHz up-translation and greater than 100MHz down-translation at up to 30pF capacitive load. This allows it to support a range of PC or consumer interfaces including GPIO, MDIO, SDIO, UART, SMBus, PMBus, I2C, and SPI. It provides voltage level shifting without direction pin control, which minimises system effort.

The level shifter operates between 0.9V and 5V across eight I/O channels, each of which can be configured with different voltage translation levels for system flexibility. Low on-resistance yields minimal signal distortion, while the wider translation voltage range of the PI4ULS5V108 suits consumer interfaces, assures Diodes. Enable and I/O pins are ESD protected (8kV HBM and 1kV CDM).

The 8-bit PI4ULS5V108 is available in the 20-pin TSSOP, or 20-pin VQFN (2.5 x 4.5mm) packages, both available on 13-inch reels.

Diodes manufactures and supplies application specific standard products within the broad discrete, logic, analogue and mixed-signal semiconductor markets. The company serves the consumer electronics, computing, communications, industrial, and automotive markets with diodes, rectifiers, transistors, MOSFETs, protection devices, function-specific arrays, single gate logic, amplifiers and comparators, Hall-effect and temperature sensors, power management devices, including LED drivers, AC-DC converters and controllers, DC/DC switching and linear voltage regulators, and voltage references along with special function devices, such as USB power switches, load switches, voltage supervisors, and motor controllers. It also provides timing, connectivity, switching, and signal integrity for high-speed signals.
