Product details
Overview
TS5A3159MDBVREP from Texas Instruments is a radiation-hardened, enhanced-product (EP) single-pole double-throw (SPDT) analog switch optimized for low-distortion signal routing in portable audio and precision instrumentation. It delivers 1.1 Ω typical ON-state resistance, 0.1 Ω channel-to-channel resistance matching, 100 MHz bandwidth, and break-before-make switching across 1.65 V to 5.5 V supply operation - enabling reliable signal path selection in space-grade or extended-temperature industrial systems.
For engineers reviewing the TS5A3159MDBVREP datasheet, TS5A3159MDBVREP pinout, TS5A3159MDBVREP application, or TS5A3159MDBVREP equivalent, key selection criteria include its 12 ns break-before-make time, ±20 nA OFF leakage at 125°C, 36 pC charge injection at 5 V, THD of 0.01% at 5 V, and SOT-23 (DBV) 6-pin package with -55°C to +125°C operating range.
Technical Context
The TS5A3159MDBVREP implements a CMOS transmission-gate architecture with controlled threshold design to maintain low ron flatness (0.15 Ω) over input voltage range and temperature. Its digital control input (IN) accepts 5-V-tolerant logic levels and drives complementary NMOS/PMOS pairs to ensure monotonic switching and minimal charge injection during state transitions.
Break-before-make timing is enforced via internal delay circuitry to prevent momentary shorting between NC and NO paths during COM re-routing. The device achieves –65 dB OFF isolation and –66 dB crosstalk at 1 MHz while maintaining <0.01% total harmonic distortion in audio-band signals under 600 Ω load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-state resistance (ron) | 1.1 Ω at V+ = 5 V - ensures minimal insertion loss and voltage drop in analog signal paths |
| Break-before-make time (tBBM) | 12 ns - prevents signal shorting during channel switching in multiplexed audio or sensor interfaces |
| Charge injection (QC) | 36 pC at 5 V - limits transient glitches on high-impedance nodes such as ADC inputs or op-amp summing junctions |
| Total harmonic distortion (THD) | 0.01% at 5 V - supports high-fidelity audio routing without audible degradation |
| Bandwidth (BW) | 100 MHz - enables use in video switching, RF sampling, and wideband test equipment |
| 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 and analog subsystems |
| OFF isolation (OISO) | –65 dB at 1 MHz - suppresses unwanted coupling between inactive and active signal paths |
Pinout & Package
SOT-23 (DBV) 6-pin plastic package with exposed pad not present; footprint compatible with JEDEC MO-178AA standard; thermal resistance θJA = 165°C/W; rated for –55°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally open analog terminal | Connects to COM only when IN = HIGH; used for primary signal path selection |
| 2 (GND) | Digital ground reference | Provides return path for control logic; must be tied to system digital ground plane |
| 3 (NC) | Normally closed analog terminal | Connects to COM only when IN = LOW; provides complementary signal path |
| 4 (COM) | Common analog port | Shared I/O node routed to either NO or NC based on IN logic state |
| 5 (V+) | Positive supply rail | Powers analog switch core and level-shifting circuitry; accepts 1.65–5.5 V |
| 6 (IN) | Digital control input | 5-V-tolerant CMOS input that selects NO→COM (HIGH) or NC→COM (LOW) |
Key Features
| Feature | Design Value |
|---|---|
| Specified break-before-make switching | Guarantees 12 ns minimum dead time between NC and NO conduction, eliminating signal shorting in critical multiplexer applications |
| Low ON-state resistance matching (∆ron) | 0.1 Ω max mismatch ensures balanced gain and phase response when routing differential or matched-signal pairs |
| Control inputs 5-V tolerant | Allows direct interfacing with legacy 5-V microcontrollers or FPGAs without level-shifting circuitry |
| Low total harmonic distortion (THD) | 0.01% at 5 V enables transparent audio signal routing in headset, microphone, and codec switching applications |
| Enhanced product qualification pedigree | Qualified per JEDEC standards including HAST, temperature cycling, and electromigration testing for extended-life reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A3157MDBVREP | Single-pole single-throw (SPST) configuration; no NC path; lower ron (0.9 Ω) but no break-before-make guarantee | Only suitable for simple ON/OFF gating, not signal path selection between two sources | Select when only one analog path needs enabling/disabling and space/power constraints favor simpler topology |
| TMUX1574RTER | 4-channel SPDT with 1.3 Ω ron, 3.6-V max supply, and integrated fault protection; no EP qualification | Supports multi-channel routing but lacks radiation hardening and extended temperature range | Prefer for commercial-grade multi-signal systems where fault tolerance matters more than space qualification |
Compared with TS5A3159MDBVREP, TS5A3157MDBVREP offers lower ron but eliminates NC path and break-before-make assurance, while TMUX1574RTER adds channel count and protection at the cost of EP reliability and 5.5-V operation - making TS5A3159MDBVREP uniquely suited for mission-critical dual-path switching in harsh environments.

FAQ
What is the maximum operating temperature range for the TS5A3159MDBVREP?
The TS5A3159MDBVREP is rated for continuous operation from –55°C to +125°C ambient temperature, validated through JEDEC-qualified thermal cycling, HAST, and bias life testing per its enhanced-product pedigree. This range applies to both electrical performance and reliability metrics including leakage current, ron, and THD - all specified across the full temperature span in the official datasheet.
Does the TS5A3159MDBVREP require external pull-up or pull-down resistors on the IN pin?
No, the TS5A3159MDBVREP does not require external biasing on the IN pin. Its CMOS input has rail-to-rail logic thresholds (VIH = 2.4 V min, VIL = 0.8 V max at 5 V supply) and sub-1 µA leakage (IIH/IIL), allowing direct connection to microcontroller GPIOs or FPGA outputs without pull resistors. Internal input structure ensures clean switching even with slow-rising control signals.
Can the TS5A3159MDBVREP safely switch signals exceeding the V+ supply rail?
No, the TS5A3159MDBVREP cannot switch analog signals beyond its absolute maximum ratings: VNO/VNC/VCOM must remain within –0.5 V to V+ + 0.5 V. Exceeding this range risks forward-biasing internal ESD diodes, causing excessive current flow (>±50 mA clamp limit) and potential damage. For rail-to-rail or overvoltage signal routing, external clamping or dedicated overvoltage-protected switches are required.
How does the TS5A3159MDBVREP achieve low THD in audio applications?
The TS5A3159MDBVREP achieves 0.01% THD through symmetric CMOS transmission-gate design, tight ron matching (0.1 Ω), low charge injection (36 pC), and flat ron vs. voltage (0.15 Ω variation). These features minimize nonlinear distortion and transient-induced harmonics when routing line-level or headphone-drive signals into 600 Ω loads - as verified in Figure 21 of the TS5A3159MDBVREP datasheet.
Is the TS5A3159MDBVREP pin-compatible with the commercial TS5A3159?
Yes, the TS5A3159MDBVREP shares identical SOT-23 (DBV) 6-pin package, pinout, and footprint with the commercial TS5A3159. Both devices use the same JA8R top-side marking and support identical PCB layout - enabling drop-in replacement where enhanced reliability, extended temperature, and radiation-hardened operation are required without board redesign.
