HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING
DATASHEET
IDTHS221P10
Description
The IDTHS221P10 is a high-performance hybrid switch
device, combined with hybrid low distortion audio and USB
2.0 high speed data (480 Mbps) signal switches, and
analog switches. When operated with a 1.8 V single supply,
this high performance switch allows audio signal swings
below-ground, allowing the use of a common USB and
audio headphone connector in personal media players and
other portable battery powered devices.
The IDTHS221P10 logic SEL control pin is 1.8 V
compatible which allows for control via a standard
µcontroller. With a VDD voltage in the range of 1.7 V to 1.95
V, the device can pass USB 3 V signal sources in the
portable device, with up to 5.5 V tolerant on USB and COM
signal pins. The part has an audio enable control pin to
open all the switches and put the part in a low power state.
The IDTHS221P10 is available in a small 10-pin µMLP
package.
