SCDS300D July 2010 – August 2016 TS3USB221A-Q1
The TS3USB221A-Q1 device is a 2-channel SPDT switch specially designed for the switching of high-speed USB 2.0 signals in automotive applications, such as USB hubs. The wide bandwidth (900 MHz) of this switch allows signals to pass with minimum edge and phase distortion. The device multiplexes differential outputs from a USB host device to one of two corresponding outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. The device also has a low power mode that will reduce the power consumption to 1 µA for portable applications with a battery or limited power budget.
The device is designed for low bit-to-bit skew and high channel-to-channel noise isolation, and is compatible with various standards, such as high-speed USB 2.0 (480 Mbps).
The TS3USB221A-Q1 device integrates ESD protection cells on all pins, is available in a tiny UQFN package
(2 mm × 1.5 mm) and is characterized over the free air temperature range from –40°C to 125°C.
The TS3USB221A-Q1 has a low power mode that reduces the power consumption to 1 µA while the devices is not in use. To put the device in low power mode and disable the switch, the bus-switch enable pin OE must be supplied with a logic High signal.
