NCN1188
3:1 High Speed USB Switch
with Audio and MHL
Capability
The NCN1188 allows portable systems to share a single USB 2.0 or
3.0 receptacle to transmit and receive paired signals from three
separate locations. All of the three differential channels are compliant
to High Speed USB 2.0, Full Speed USB 1.1, Low Speed USB 1.0 and
any generic UART protocol. The two dedicated high speed data paths
also support Mobile High Definition Link (MHL) video up to 720p,
60fps and 1080i, 30fps. The multi−purpose audio path is capable of
passing signals with negative voltages as low as 2 V below ground and
features shunt resistors to reduce Pop and Click noise in the audio
system. The NCN1188 is housed in a space saving, ultra low profile
2.0 x 1.7 x 0.5 mm, 12 pins UQFN package.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at T
A
= 25°C.
2. Latch up Current Maximum Rating:
±100
mA per JEDEC standard: JESD78.
3. This device series contains ESD protection and passes the following tests:
Human Body Model (HBM)
±4.0
kV per JEDEC standard: JESD22−A114 for all pins.
Machine Model (MM)
