Low Voltage, Dual SPDT, USB/CVBS/
Audio Switches with Negative Signal
Capability
The Intersil ISL54415, ISL54416, ISL54417 dual SPDT
(Single Pole/Double Throw) switches combine low distortion
audio/video and accurate USB 2.0 Full Speed data signal
switching in the same low voltage device. When operated with
a 2.5V to 3.6V single supply these analog switches allow
audio/video signal swings below-ground, allowing the use of a
common USB and audio/video connector in digital cameras,
camcorders and other portable battery powered Personal
Media Player devices.
The ISL54415 and ISL54416 incorporate circuitry for
detection of the USB V_BUS voltage, which is used to switch
between the audio/video and USB signal source in the
portable device. In addition, the ISL54415 includes circuitry for
generation of a V_TERM voltage of 3.3V for use with USB
speed setting pull-up resistor.
The ISL54415, ISL54416, ISL54417 are available in a tiny
10Ld 2.1mm x 1.6mm ultra-thin μTQFN package. They
operate over a temperature range of -40 to +85°C.
