PI4MSD5V9548ALEX Description

Short technical summary and product information.

The DIODES™ PI4MSD5V9548A is an octal bidirectional translating switch controlled via the I2C bus. The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register.

This switch operates with a power supply voltage range of 1.65V to 5.5V, allowing voltage level translation between various bus voltages including 1.2V, 1.8V, 2.5V, 3.3V, and 5V. It supports I2C-bus interface logic and a clock frequency of up to 400 kHz.

Key features include an active LOW reset input for recovery from bus issues, low standby current, and low Ron switches. The device supports hot insertion and has 5V tolerant inputs. ESD protection exceeds 8000V HBM and 1000V CDM. Latch-up testing exceeds 100mA per JEDEC Standard JESD78.

Available in 24-pin TSSOP and 24-pin TQFN packages, the PI4MSD5V9548A is designed for applications requiring flexible I2C bus management and voltage level translation.
