TCA9548APWR Manufacturer: Texas Instruments (TI)

#### Key Specifications:

  • Part Number: TCA9548APWR
  • Type: 8-Channel I²C Bus/SMBus Multiplexer
  • Package: TSSOP-24
  • Supply Voltage Range: 1.65V to 5.5V
  • Operating Temperature Range: -40°C to +85°C
  • I²C Bus Frequency: Up to 400 kHz
  • Channels: 8 bidirectional translating switches
  • Interrupt Input: Supports interrupt monitoring
  • Low Standby Current: < 1 µA

#### Descriptions:

The TCA9548APWR is an I²C/SMBus multiplexer that allows communication with multiple I²C devices sharing the same bus. It features 8 bidirectional switches, enabling selection between different I²C buses. The device supports voltage level translation between 1.8V, 2.5V, 3.3V, and 5V buses.

#### Features:

  • 8-Channel I²C Switch: Selects one of 8 downstream I²C buses.
  • Voltage-Level Translation: Works across mixed-voltage systems (1.65V to 5.5V).
  • Low Standby Current: Consumes < 1 µA when powered down.
  • Interrupt Handling: Supports interrupt signals from downstream devices.
  • Hot Insertion Protection: Prevents glitches during power-up.
  • Software Reset: Allows system recovery via I²C command.

This device is commonly used in applications requiring multiple I²C buses, such as servers, industrial systems, and embedded designs.
