Bidirectional 8-channel Level Shifter from Diodes

Diodes has unveiled the PI4ULS5V108, an 8-channel, high speed, bidirectional level shifter designed for inter-IC communications between devices operating on different voltage supply rails.

Targeted applications include PC, servers, networking, telecom, and consumer electronics.

The PI4ULS5V108 supports up to 100 MHz up-translation and greater than 100 MHz down-translation at ≤30pF capacitive load, which allows it to support a wide 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.

This 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.

On-resistance is very low, yielding minimal signal distortion, while the wider translation voltage range of the PI4ULS5V108 suits consumer interfaces. 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 2.5mm x 4.5mm packages, both available on 13” reels.
