Product details
Overview
TS5A2066DCUR from Texas Instruments is a dual-channel SPST analog switch in VSSOP-8 package, featuring 10 Ω typical ON-state resistance at 5 V, 1.65–5.5 V single-supply operation, and 5-V-tolerant control inputs. It routes audio/video signals and low-voltage analog data in portable electronics with low charge injection (1 pC) and THD of 0.01% at 5 V.
For engineers reviewing the TS5A2066DCUR datasheet, TS5A2066DCUR pinout, TS5A2066DCUR application, or TS5A2066DCUR equivalent, key selection criteria include ON-resistance matching (≤1 Ω), bandwidth (300 MHz), OFF isolation (–68 dB), and compatibility with 1.8-V to 5.5-V logic control in space-constrained PCB layouts.
Technical Context
The TS5A2066DCUR implements two independent bidirectional SPST switches with CMOS transmission-gate architecture. Each channel supports rail-to-rail analog signal handling up to VCC and maintains consistent ON-resistance flatness (≤5 Ω) across its full voltage range.
Its 5-V-tolerant IN1/IN2 inputs enable direct interfacing with legacy 5-V microcontrollers while operating from as low as 1.65 V. Charge injection (≤1 pC) and low THD (0.01% at 5 V) ensure minimal signal corruption in precision sampling and audio routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-state resistance | 10 Ω typical at 5 V - enables low insertion loss for analog signals up to 300 MHz bandwidth |
| Supply voltage range | 1.65 V to 5.5 V - supports direct integration into 1.8-V, 2.5-V, 3.3-V, and 5-V systems without level shifters |
| Control input tolerance | 5-V tolerant - allows use with 5-V GPIOs even when VCC = 1.8 V, simplifying mixed-voltage designs |
| Charge injection | 1 pC max at 5 V - minimizes voltage glitch on sampled nodes in precision ADC front-ends |
| THD | 0.01% at 5 V - preserves audio fidelity in headset switching and line-level signal routing |
| OFF isolation | –68 dB at 10 MHz - prevents crosstalk between active and inactive channels in multi-source routing |
| Bandwidth | 300 MHz - supports high-speed video (e.g., VGA, DVI auxiliary) and fast digital signal switching |
Pinout & Package
VSSOP-8 (DCU) package: 2.30 mm × 2.00 mm body, 0.5-mm lead pitch, exposed pad optional. Compact footprint ideal for portable and space-constrained designs.

| 3 (IN2) | Digital control input for Channel 2 | 5-V-tolerant logic input; high = connect COM2–NO2, low = open |
| 4 (GND) | Analog and digital ground reference | Single ground connection for both switch channels and control logic |
| 5 (NO2) | Normally open terminal of Channel 2 | Bidirectional analog path connected to COM2 only when IN2 = high |
| 6 (COM2) | Common terminal of Channel 2 | Second independent analog I/O node; electrically isolated from COM1 |
| 7 (IN1) | Digital control input for Channel 1 | 5-V-tolerant logic input; high = connect COM1–NO1, low = open |
| 8 (VCC) | Positive supply rail | Single power supply for analog path and control logic; no separate VDD required |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574DCUR | Lower ON-resistance (0.5 Ω typ), higher supply current (10 µA), requires ≥2.5 V supply | Better for high-precision instrumentation; not suitable for 1.8-V-only systems | Select TMUX1574DCUR when sub-1-Ω resistance and 300-MHz bandwidth are critical and supply ≥2.5 V is available. |
| ADG708BRUZ | 8-channel MUX (not dual SPST), 4 Ω ON-resistance, 2.7–5.5 V supply, SPI interface | Suitable for multi-sensor scanning but adds protocol overhead and larger footprint | Choose ADG708BRUZ only when >2 channels are needed and SPI control is acceptable over GPIO simplicity. |
Compared with TMUX1574DCUR and ADG708BRUZ, the TS5A2066DCUR offers optimal balance of ultra-low voltage operation (1.65 V), GPIO simplicity, and proven performance in portable audio/video routing-making it the preferred choice where compact dual-switch functionality and wide supply flexibility are essential.

FAQ
What is the maximum analog signal voltage the TS5A2066DCUR can handle?
The TS5A2066DCUR supports rail-to-rail analog signals from 0 V to VCC. When VCC = 5.5 V, the analog voltage range is 0 V to 5.5 V. This bidirectional capability allows the TS5A2066DCUR to pass signals exceeding logic levels without distortion, making it suitable for interfacing sensors, audio codecs, and video drivers directly.
Does the TS5A2066DCUR require external pull-up or pull-down resistors on its IN1 and IN2 pins?
No, the TS5A2066DCUR does not require external biasing on IN1 or IN2. Its control inputs have internal leakage-limited structure and specified VIH/VIL thresholds (e.g., VIH ≥ 0.7×VCC). As long as driving GPIOs meet these logic levels, the TS5A2066DCUR operates reliably without external resistors-reducing BOM count and board area in the TS5A2066DCUR design.
Can the TS5A2066DCUR be used in audio line-level switching applications?
Yes, the TS5A2066DCUR is well-suited for audio line-level switching. With 0.01% THD at 5 V, 10 Ω ON-resistance, and 300 MHz bandwidth, it preserves signal integrity for stereo headphone, microphone, and auxiliary inputs. Its low charge injection (1 pC) prevents audible pops during switching, and the dual independent channels support left/right or input/output routing in the TS5A2066DCUR implementation.
What is the thermal performance of the TS5A2066DCUR in VSSOP-8 (DCU) package?
The TS5A2066DCUR in VSSOP-8 (DCU) package has a junction-to-ambient thermal resistance (RθJA) of 212.8°C/W and junction-to-board (RθJB) of 133.6°C/W. Under typical 1-mA analog load and 5-V supply, power dissipation remains below 10 mW, resulting in negligible temperature rise-ensuring stable TS5A2066DCUR operation in sealed enclosures or stacked PCB assemblies.
Is the TS5A2066DCUR compatible with 1.8-V microcontroller GPIOs?
Yes, the TS5A2066DCUR is fully compatible with 1.8-V microcontrollers. Its control inputs are 5-V tolerant and recognize VIH ≥ 1.25 V (at VCC = 1.8 V) as logic high. Since most 1.8-V GPIOs drive >1.4 V for high output, they directly satisfy TS5A2066DCUR's input threshold-enabling seamless integration without level-shifting circuitry in the TS5A2066DCUR system design.
