NCN1154
USB 2.0 High Speed, UART
and Audio Switch with
Negative Signal Capability
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. The device 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 Passing Negative Swing Signals Down to −2 V on R/L
Channel
1.8 V Compatible Control Pins for 2.7 V v VCC v 4.2 V
Audio Channel Shunt Resistors for Pop & Click Noise Reduction
Ultra Low THD in Audio Mode: 0.01% into 16 W Load
5.25 V Tolerant Common Pins
This is a Pb−Free Device
Typical Applications
Micro or Mini USB Applications
Shared High Speed Data or Audio on a Single Connector

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
NOTE: These devices have limited built−in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage.
