TCUA231WBG
1. Functional Description
•
USB 2.0 High-Speed, UART, and Audio Switch with Negative Signal Capability
2. General
The TCUA231WBG is a dual SP3T switch for combined USB 2.0 High-Speed , audio and UART signals.
The audio switch is designed to allow audio signals to swing below ground.
When VBUS is High, the USB switches (D+ and D-) are selected, regardless of the logic levels of the Head and
Man inputs. When VBUS is Low or left open and Head is Low, the Audio switches (R and L) are selected. When
VBUS is Low or left open, Head is High and Man is Low, the UART switches (TX and RX) are selected.
All the inputs are protected against electrostatic discharge.

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).
