Bi-directional level shifter targets telecomms and networks

The PI4ULS5V108 is designed for inter-IC communications between devices operating on different voltage supply rails, for example PCs, servers, networking, telecomms and consumer electronics.

 

It supports up to 100MHz up-translation and greater than 100MHz down-translation at 30pF capacitive load or less. This allows it to support a wide range of PC or consumer interfaces including general purpose I/O (GPIO), management data I/O (MDIO), secure digital I/O (SDIO), Universal Asynchronous Receiver/Transmitter (UART), system management bus (SMBus), power management bus (PMBus), inter-integrated circuit (I2C), and serial peripheral interface (SPI), explains the company. It provides voltage level shifting without direction pin control.

 

The level shifter operates between 0.9 and 5.0V across eight I/O channels, each of which can be configured with different voltage translation levels. On-resistance is low for minimal signal distortion, reports the company and the wider translation voltage range suits consumer interfaces. Enable and I/O pins are ESD-protected to 8kV HBM (human body model) and 1kV CDM (charge device model).

 

The 8-bit PI4ULS5V108 is available in the 20-pin TSSOP, or 20-pin VQFN 2.5 x 4.5mm packages.
