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 V_BUS is High, the USB switches (D+ and D-) are selected, regardless of the logic levels of the Head and
Man inputs. When V_BUS is Low or left open and Head is Low, the Audio switches (R and L) are selected. When
V_BUS 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.
3. Features
(1) Supply voltage: V_CC = 2.3 to 3.6 V
(2) Switch terminal ON-capacitance (D+, D-): C_I/O = 8 pF Switch ON (typ.) @V_CC = 3.3 V
(3) ON-resistance (D+, D-): R_ON = 6.5 Ω (typ.) @V_CC = 3 V, V_IS = 0 V
(4) ON-resistance (R, L): R_ON = 5.5 Ω (typ.) @V_CC = 3 V, V_IS = 0 V
(5) ON-resistance flatness (R, L): R_ON(flat) = 2 Ω (typ.) @V_CC = 3 V
(6) ESD performance: Machine model ≥ ±200 V, Human body model ≥ ±2000 V
(7) Package: WCSP15 (1.6 mm × 1.6 mm)
