The PI4ULS5V108 from Diodes Incorporated is 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 ≤30 pF capacitive load. This 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 <0,9 V and 5 V 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 wide translation voltage range suits consumer interfaces. Enable and I/O pins are ESD protected (8 kV HBM and 1 kV CDM).
The 8-bit PI4ULS5V108 is available in the 20-pin TSSOP or 20-pin VQFN 2,5 mm x 4,5 mm packages.
