Overview

USB 2.0 High Speed, UART and Audio Switch with Negative Signal Capability NCN1154 The NCN1154 is a DP3T switch for combined true−ground audio, USB 2.0 high speed data, and UART applications.

It allows portable systems to use a single port to pass either high speed data or audio signals from an external headset; the 3 channels being compliant to USB 2.0, USB 1.1 and USB 1.0.

The switch is capable of passing signals with negative voltages as low as 2 V below ground.

Key Features

  • shunt resistors on the audio ports. These resistors are switched in when the audio channel is off and provide a safe path to ground for any charge that may build up on the audio lines. This reduces Pop & Click noise in the audio system. The NCN1154 is housed in a space.
  • saving, ultra low profile 2.0x1.7x0.5mm, 12 pin UQFN package. Features.
  • 3:1 High Speed Switch.
  • USB 2.0, USB 1.1 & USB 1.0 Capable on all Channels.
  • High Bandwidth of 820 MHz on D+/D.
  • Capable of.
