Product details
Overview
TS5A3159 from Texas Instruments is a single-pole double-throw (SPDT) analog switch designed for bidirectional signal routing in portable audio and low-voltage systems. It operates from 1.65 V to 5.5 V, delivers 1 Ω typical ON-state resistance at 5 V, features break-before-make switching, and maintains ≤0.1 Ω ON-resistance matching - enabling low-distortion signal transfer in mobile phone audio paths and consumer instrumentation interfaces.
For engineers reviewing the TS5A3159 datasheet, TS5A3159 pinout, TS5A3159 application, or TS5A3159 equivalent, key selection criteria include its 1.65–5.5 V supply range, 1 Ω rON, 35 ns tON/20 ns tOFF at 5 V, ±2000-V HBM ESD rating, and SC-70-6 (DCK) package compatibility with space-constrained PCB layouts.
Technical Context
The TS5A3159 implements a CMOS transmission-gate architecture with integrated level-shifting control logic, enabling 5-V-tolerant IN input operation even when V+ is as low as 1.65 V. Its break-before-make timing (tBBM = 1–14.5 ns) prevents momentary shorting between NC and NO paths during state transitions.
Signal integrity is maintained via low charge injection (13–36 pC), low THD (0.01–0.025% across 1.8–5 V), and high OFF isolation (–63 to –65 dB at 1 MHz), making it suitable for audio channel switching where DC offset and crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V logic and analog rails without level shifters |
| ON-State Resistance (rON) | 1.1 Ω typ at 5 V, 1.5 Ω typ at 3.3 V - ensures minimal voltage drop and power loss in audio and sensor signal paths |
| ON-Resistance Matching (ΔrON) | 0.1 Ω max at 5 V - guarantees matched gain/attenuation between NC and NO channels for differential or stereo switching |
| Break-Before-Make Time (tBBM) | 1–14.5 ns - eliminates signal shorting during channel transition, critical for preventing audio pop/click |
| Charge Injection | 13 pC at 1.8 V, 36 pC at 5 V - limits DC offset step on downstream capacitors, preserving baseline stability in AC-coupled circuits |
| Total Harmonic Distortion (THD) | 0.01% at 5 V, 0.015% at 3.3 V - preserves fidelity in audio-band signals up to 20 kHz |
| ESD Rating (HBM) | ±2000 V - meets IEC 61000-4-2 Level 2 requirements for handheld device front-end protection |
Pinout & Package
TS5A3159 is packaged in a 6-pin SC-70 (DCK) case measuring 2.00 mm × 1.25 mm, optimized for high-density portable PCBs. The package is RoHS-compliant and moisture-sensitive level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally open switch port | Connected to COM only when IN = HIGH; remains open otherwise - used for alternate signal path selection |
| 2 - GND | Ground reference | Return path for internal biasing and ESD protection; must be low-impedance to minimize noise coupling |
| 3 - NC | Normally closed switch port | Connected to COM when IN = LOW; default path for fail-safe or standby routing |
| 4 - COM | Common analog I/O terminal | Bidirectional signal hub - routes analog signals between NC and NO based on IN logic state |
| 5 - V+ | Positive supply rail | Single power source for analog and digital sections; sets signal swing range (0 to V+) |
| 6 - IN | Digital control input | 5-V-tolerant logic select: HIGH → COM↔NO, LOW → COM↔NC; no external pull-up required |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees no overlap between NC and NO conduction, eliminating transient shorts in audio multiplexing |
| 1.65-V to 5.5-V single-supply operation | Enables direct integration into mixed-voltage systems (e.g., 1.8-V MCU controlling 3.3-V audio codec) |
| 5-V-tolerant IN input | Allows use of legacy 5-V GPIOs to control low-voltage analog paths without external level translators |
| Low THD (0.01%) and high OFF isolation (–65 dB) | Maintains signal purity in stereo headphone switching and microphone path selection |
| Low charge injection (13–36 pC) | Reduces DC settling time in capacitor-coupled amplifier inputs and ADC front-ends |
| Latch-up immunity (>100 mA per JESD78 Class II) | Ensures robustness against transient overvoltage events in battery-powered consumer devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574DCKR | Higher rON (1.8 Ω), lower THD (0.003%), 1.08-V min supply, but no 5-V-tolerant IN | Better for ultra-low-noise audio; requires level-shifter if driven by 5-V MCU | Select for <1.8-V systems or when THD <0.005% is mandatory; avoid if 5-V GPIO control is needed |
| ADG858BRMZ-REEL | Lower rON (0.5 Ω), higher supply max (5.5 V), but only 1.65–5.5 V logic-compatible IN (not 5-V tolerant) | Superior signal integrity in high-fidelity DAC outputs; lacks 5-V IN margin for industrial GPIOs | Prefer for premium audio routing where rON <0.7 Ω is critical; verify MCU IO voltage compatibility before substitution |
Compared with TMUX1574DCKR and ADG858BRMZ-REEL, TS5A3159 uniquely balances 5-V-tolerant control, 1-Ω rON, and SC-70 size - making it optimal for cost-sensitive, space-constrained portable designs requiring robust GPIO interfacing without external components.

FAQ
What is the maximum supply voltage rating for the TS5A3159?
The TS5A3159 has an absolute maximum supply voltage (V+) of 6.5 V, but its recommended operating range is 1.65 V to 5.5 V. Operating above 5.5 V risks exceeding electrical specifications and may degrade reliability; sustained use at 6.5 V is not advised per the datasheet's Absolute Maximum Ratings table.
Does the TS5A3159 support bidirectional analog signal flow?
Yes, the TS5A3159 is fully bidirectional: analog signals can pass from COM to NC/NO or from NC/NO to COM with identical rON, capacitance, and distortion characteristics. This enables flexible routing in both source-to-load and load-to-source configurations without performance penalty.
Can the TS5A3159 be used with a 1.8-V microcontroller GPIO without level shifting?
Yes - the TS5A3159's IN pin is 5-V tolerant and functions correctly with 1.8-V logic inputs. When V+ = 1.8 V, VIH is specified as 1.5 V min and VIL as 0.6 V max, ensuring reliable recognition of standard 1.8-V CMOS logic levels without external translation circuitry.
What is the typical ON-state resistance flatness of the TS5A3159 at 3.3 V?
At V+ = 3.3 V and TA = 25°C, the TS5A3159 exhibits 0.225 Ω typical ON-state resistance flatness (rON(flat)) - defined as the variation in rON across the full analog signal range (0 V to 3.3 V). This ensures consistent attenuation and minimal harmonic generation in wide-swing audio applications.
Is the TS5A3159 pin-compatible with other SC-70-6 analog switches like the TS5A3157?
No - the TS5A3159 and TS5A3157 have different pinouts: TS5A3159 uses Pin 1=NO, Pin 3=NC, Pin 4=COM, while TS5A3157 uses Pin 1=NC, Pin 3=NO, Pin 4=COM. Swapping them requires PCB layout revision; they are functionally similar but not pin-compatible replacements.
