Product details
Overview
TS5A3359DCUR from Texas Instruments is a bidirectional SP3T analog switch IC designed for low-distortion signal routing in portable electronics. It delivers 1.1 Ω typical ON-state resistance at 5 V, 5 pC charge injection at 1.8 V, and break-before-make switching - enabling clean audio/video path selection in battery-powered devices such as smartphones and PDAs.
For engineers reviewing the TS5A3359DCUR datasheet, TS5A3359DCUR pinout, TS5A3359DCUR application, or TS5A3359DCUR equivalent, this page provides verified electrical specs, package mapping to US8 (8-pin), functional pin roles, real-world use cases in audio routing and data acquisition, and two validated alternative parts with documented differences.
Technical Context
The TS5A3359DCUR implements a single-pole triple-throw (SP3T) topology with three normally-open (NO0–NO2) paths routed to a common (COM) terminal via dual digital control inputs (IN1, IN2). Its CMOS-based switch architecture supports rail-to-rail analog signal handling from 0 V to VCC across 1.65 V–5.5 V supply range.
Break-before-make timing (0.5–80 ns depending on VCC) prevents momentary shorting during channel transitions, while isolation in power-down mode (VCC = 0 V) ensures <1 μA leakage. THD of 0.005% at 5 V enables high-fidelity audio signal integrity without added filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-state resistance (ron) | 0.9 Ω typ @ 4.5 V - enables minimal voltage drop and insertion loss in 5-V signal paths |
| Charge injection | 5 pC @ 1.8 V - reduces glitch-induced DC offset in precision sampling circuits |
| Bandwidth | 75 MHz @ 5 V - supports composite video and USB 1.1 data rates without attenuation |
| OFF isolation | –64 dB @ 1 MHz - suppresses crosstalk between inactive channels in multi-source systems |
| Supply voltage range | 1.65 V to 5.5 V - allows direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| Control input tolerance | 5.5 V tolerant - permits use with higher-voltage controllers without level-shifting |
| Total harmonic distortion | 0.005% @ 5 V - preserves audio fidelity in headset and speaker routing applications |
Pinout & Package
TS5A3359DCUR is packaged in an 8-pin US8 (DCU) surface-mount package measuring 2.30 mm × 2.00 mm, optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| NO0 | Analog I/O (normally open) | First selectable signal path; connects to COM when IN1=LOW, IN2=LOW |
| NO1 | Analog I/O (normally open) | Second selectable path; connects to COM when IN1=HIGH, IN2=LOW |
| NO2 | Analog I/O (normally open) | Third selectable path; connects to COM when IN1=LOW, IN2=HIGH |
| GND | Ground reference | Return path for analog and digital signals; must be low-impedance for THD performance |
| IN2 | Digital control input | MSB of 2-bit select code; HIGH enables NO2 path, LOW enables NO0/NO1 |
| IN1 | Digital control input | LSB of 2-bit select code; determines NO0 vs NO1 when IN2=LOW |
| COM | Analog I/O (common terminal) | Shared signal hub; routes bidirectionally to selected NOx path |
| VCC | Positive supply | Power rail for internal logic and switch bias; also defines analog signal range (0 to VCC) |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees no overlap between channel connections, preventing signal shorting during reconfiguration |
| Isolation at VCC = 0 V | Maintains >1 MΩ off-state impedance even with unpowered supply, critical for hot-swap safety |
| Low ON-resistance matching (0.1 Ω max) | Ensures consistent gain and phase response across all three channels in instrumentation multiplexing |
| 5.5-V tolerant control inputs | Eliminates need for external level shifters when interfacing with 5-V microcontrollers or FPGAs |
| 1.65–5.5-V single-supply operation | Reduces BOM count by supporting mixed-voltage systems without auxiliary regulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | 2-channel bidirectional level shifter (not SP3T); no analog switching capability; 5-V tolerant I/O but no ron spec | Designed for digital logic translation only; unsuitable for analog signal routing or audio paths | Select TS5A3359DCUR for analog multiplexing; TXS0102DCUR only if digital level shifting is required |
| TMUX1574RTER | SP4T configuration; 0.7 Ω ron @ 3.3 V; 1.5-pC charge injection; requires 1.08–4.5-V supply | Supports four inputs instead of three; lower ron and charge injection, but larger 16-pin WQFN package (3.0 × 2.5 mm) | Choose TMUX1574RTER for higher channel count or lower distortion; TS5A3359DCUR for compact 8-pin SP3T fit |
Compared with TXS0102DCUR, TS5A3359DCUR provides true analog switching with sub-1-Ω resistance and THD-optimized performance; versus TMUX1574RTER, it trades one channel and slightly higher ron for 30% smaller footprint and broader supply compatibility (1.65–5.5 V).

FAQ
What is the maximum analog signal voltage range supported by the TS5A3359DCUR?
The TS5A3359DCUR supports rail-to-rail analog signals from 0 V to VCC. With a supply range of 1.65 V to 5.5 V, the analog input/output voltage range scales accordingly - e.g., 0–3.3 V at 3.3 V supply, or 0–5.5 V at 5.5 V supply. Exceeding VCC + 0.5 V on any analog pin violates absolute maximum ratings and risks damage.
Does the TS5A3359DCUR require external pull-up or pull-down resistors on its control inputs?
No. The TS5A3359DCUR control inputs (IN1, IN2) have CMOS-compatible thresholds and do not require external biasing. However, TI recommends tying unused inputs directly to VCC or GND to prevent floating states that could cause erratic switching or increased ICC. The device specifies VIH ≥ 2.4 V (5 V supply) and VIL ≤ 0.8 V, ensuring robust logic recognition.
Can the TS5A3359DCUR be used in audio line-level applications with 2-VRMS signals?
Yes. At 3.3 V or 5 V supply, the TS5A3359DCUR supports full 2-VRMS (≈5.6 VPP) audio signals without clipping, given its 0–VCC analog range and 0.01% THD at 3.3 V. Its 78 pF ON capacitance and 75 MHz bandwidth preserve frequency response up to 20 kHz with minimal phase shift, making it suitable for line-out/headphone switching in consumer audio.
How does the TS5A3359DCUR behave when VCC is disconnected during operation?
When VCC = 0 V, the TS5A3359DCUR enters power-down isolation mode: all switches turn OFF, and leakage currents drop to ≤1 μA (ICOM(PWROFF), INO(PWROFF)). This prevents signal bleed-through and protects downstream circuitry - a key requirement for hot-plug interfaces and battery-backed systems where supply sequencing is uncontrolled.
What is the recommended PCB layout practice to minimize crosstalk in TS5A3359DCUR designs?
To minimize crosstalk, route analog traces (NO0–NO2, COM) with tight coupling to ground planes, avoid parallel runs longer than 5 mm between adjacent NO pins, and place 0.1-μF decoupling capacitors within 2 mm of the VCC pin. TI's layout guidelines emphasize separating digital (IN1/IN2) and analog sections, using guard traces tied to GND around sensitive analog nodes, and minimizing via stubs on high-frequency paths.
