PCA9548APW,112

Specialized Overview

The PCA9548APW,112 is an octal bidirectional translating switch controlled via the I2C-bus. It fans out one upstream SCL/SDA pair to eight downstream pairs or channels. Any individual SCx/SDx channel or combination of channels can be selected by the programmable control register. An active LOW reset input allows recovery from a downstream I2C bus stuck in a low state. The pass gates allow voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses. Operating power supply voltage ranges from 2.3 V to 5.5 V with a clock frequency of 0 Hz to 400 kHz. All I/O pins are 6 V tolerant.

Specialized Feature Summary

Octal bidirectional translating switches
I2C-bus interface logic compatible with SMBus standards
Active LOW reset input for bus fault recovery
Three address pins allowing up to eight devices on the I2C-bus

Specialized Applications

Expanding I2C bus capacity by connecting multiple devices with identical addresses
Voltage level translation between different I2C bus domains (e.g., 1.8V to 5V)
Server motherboard monitoring systems for temperature and voltage sensors

Specialized Procurement Notes

Verify the ordering suffix ',112' corresponds to the TSSOP24 package in standard marking IC's tube - DSC bulk pack configuration. Confirm the manufacturer is NXP Semiconductors and the device type matches the PCA9548A series specifications before procurement.

Specialized Selection Notes

Select this component when an I2C master requires expansion to eight independent downstream buses. Ensure the application supports the 2.3 V to 5.5 V operating range and requires hot insertion capabilities. Verify that the TSSOP24 package dimensions fit the PCB layout constraints.

Specialized Part Context

The PCA9548A is part of NXP's I2C/SMBus multiplexer and switch family. It provides hardware-level isolation for I2C devices, preventing address conflicts and enabling communication across different voltage domains without external protection circuits.
