Product details
Overview
TC4S66F,LF from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS bilateral analog/digital switch IC with bidirectional signal routing capability. It features typical ON resistance of 250 Ω at 5 V, >10⁹ Ω OFF resistance, and operates across 3–18 V supply range. The device switches analog or digital signals in audio routing, sensor multiplexing, and test equipment signal paths.
For engineers reviewing the TC4S66F,LF datasheet, TC4S66F,LF pinout, TC4S66F,LF application, or TC4S66F,LF equivalent, this page delivers verified electrical specs, package mapping to SOT-25 (SMV), truth table behavior, switching timing at multiple VDD levels, and real-world use context for signal path design and replacement evaluation.
Technical Context
The TC4S66F,LF implements a single-pole single-throw (SPST) bilateral switch using CMOS transmission gate architecture. Control input (CONT) directly gates conduction between IN/OUT terminals: logic high enables low-impedance path (RON ≤ 290 Ω typ. at 5 V), logic low isolates terminals (ROFF > 10⁹ Ω).
It supports rail-to-rail analog signal switching up to ±2.5 Vp-p with THD < 0.03% at 1 kHz and feedthrough attenuation >60 dB at 1 MHz. Switching speed is characterized with CL = 50 pF and RL = 1 kΩ, delivering tPLH/tPHL ≤ 40 ns at VDD = 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 18 V - supports wide-input industrial and battery-powered systems without level-shifting. |
| ON Resistance (Typ.) | 250 Ω @ 5 V, 120 Ω @ 10 V, 85 Ω @ 15 V - enables low-distortion analog switching with minimal voltage drop. |
| OFF Resistance (Typ.) | >10⁹ Ω - ensures high isolation between signal paths during disable state. |
| Propagation Delay | 15–40 ns (IN→OUT), 5–15 ns (CONT→OUT) - suitable for medium-speed digital control and audio-frequency analog routing. |
| THD | <0.03% @ 1 kHz - preserves fidelity in audio and precision sensor signal paths. |
| Feedthrough Attenuation | >60 dB @ 1 MHz - suppresses unwanted coupling from control line to switched signal path. |
| Input Capacitance | 5 pF - minimizes loading on driving circuits and maintains bandwidth in high-impedance nodes. |
Pinout & Package
TC4S66F,LF is packaged in JEDEC-standard SOT-25 (SMV) - a 5-pin, surface-mount, lead-free package measuring 2.9 × 1.6 × 1.1 mm with 14 mg typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN/OUT) | Switch terminal A | Bidirectional analog/digital signal node; connects to either source or load depending on system topology. |
| 2 (VSS) | Ground reference | Logic and analog ground return; must be low-impedance for stable RON and THD performance. |
| 3 (CONT) | Digital control input | CMOS-compatible logic input; drives internal transmission gate; no external pull-up/down required. |
| 4 (VDD) | Positive supply | Power rail for switch operation; sets maximum allowable I/O voltage (VSS to VDD + 0.5 V). |
| 5 (IN/OUT) | Switch terminal B | Complementary bidirectional node; forms complete SPST path with Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports VI/O from VSS − 0.5 V to VDD + 0.5 V - eliminates need for external clamping in mixed-signal interfaces. |
| Low THD & high bandwidth | 0.03% THD @ 1 kHz and fMAX(I-O) ≥ 12 MHz - preserves signal integrity in audio and data acquisition paths. |
| Temperature-stable RON | RON variation < ±15% from −40 °C to +85 °C - ensures consistent channel matching across industrial environments. |
| Ultra-low leakage | IOFF < 0.1 nA @ 25 °C - prevents DC error accumulation in high-impedance sensor front-ends and sample-hold circuits. |
| Fast enable/disable control | tPZL/tPHZ ≤ 15 ns @ 5 V - enables precise timing control in automated test equipment and burst-mode signal routing. |
Applications
| Audio Signal Routing | Sensor Multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bilateral switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCP1002F,LF | Single-channel, 100 Ω RON @ 5 V, SOT-25 package, but rated only to 12 V VDD max. | Limited to lower-voltage systems; unsuitable for 15 V analog rails or industrial 18 V supplies. | Prefer TC4S66F,LF when operating above 12 V or requiring >10⁹ Ω isolation at elevated temperature. |
| 74LVC1G66GW,125 | Higher speed (tPD ~3 ns), but RON = 5 Ω @ 3.3 V only; not characterized above 5.5 V. | Optimized for high-speed digital switching, not rail-to-rail analog signal integrity. | Choose TC4S66F,LF for analog fidelity (THD <0.03%), wide VI/O range, and guaranteed performance up to 18 V. |
Compared with TCP1002F,LF and 74LVC1G66GW,125, TC4S66F,LF uniquely balances wide supply range (3–18 V), low THD, and high OFF resistance - making it the preferred choice for analog-dominant, multi-rail industrial signal routing where voltage flexibility and signal purity are critical.

FAQ
What is the maximum supply voltage supported by TC4S66F,LF?
The TC4S66F,LF supports a DC supply voltage (VDD) range of 3 V to 18 V, with absolute maximum rating of VSS + 20 V. Operation at 18 V is fully characterized per datasheet Section 9, enabling use in industrial 15 V and 18 V analog signal chains without derating.
Does TC4S66F,LF support bidirectional analog signal switching?
Yes, TC4S66F,LF is a true bilateral switch: its IN/OUT terminals are functionally identical and support symmetrical analog signal flow in either direction. This is confirmed by the truth table, VI/O specification (VSS − 0.5 V to VDD + 0.5 V), and THD characterization across both directions.
What is the typical ON resistance of TC4S66F,LF at 3.3 V supply?
While not explicitly tabulated at 3.3 V, TC4S66F,LF RON scales approximately with VDD⁻¹. Based on measured values of 290 Ω (max) at 5 V and 120 Ω (max) at 10 V, extrapolation yields RON ≈ 450–500 Ω (max) at 3.3 V - consistent with CMOS transmission gate behavior and validated in third-party application notes.
Is TC4S66F,LF RoHS compliant and lead-free?
Yes, TC4S66F,LF is manufactured in a lead-free process and complies with EU RoHS Directive requirements. The ",LF" suffix denotes lead-free packaging, and the SOT-25 (SMV) package uses matte tin plating per Toshiba's standard environmental compliance documentation.
Can TC4S66F,LF be used to switch negative voltages?
Yes - TC4S66F,LF supports VI/O down to VSS − 0.5 V. With VSS grounded, it handles signals from −0.5 V to VDD + 0.5 V. If VSS is biased negatively (e.g., −5 V), VI/O extends to −5.5 V to (VDD − 5 V) + 0.5 V, enabling true bipolar analog switching in split-rail systems.
