Product details
Overview
74LVC2G66GT,115 from Nexperia is a dual SPST bilateral analog switch optimized for signal routing in mixed-voltage systems. It operates from 1.65 V to 5.5 V, delivers ≤6 Ω typical ON resistance at 5 V, supports 32 mA switch current, and features Schmitt-trigger inputs for noise immunity. It enables level translation between 3.3 V and 5 V logic domains in USB peripheral interfaces and sensor multiplexing.
For engineers reviewing the 74LVC2G66GT,115 datasheet, 74LVC2G66GT,115 pinout, 74LVC2G66GT,115 application, or 74LVC2G66GT,115 equivalent, key selection criteria include its rail-to-rail analog switching capability, low charge injection (≤7.5 pC), high OFF-state isolation (−46 dB), fast enable time (1.0–5.0 ns), and XSON8 package compatibility with space-constrained PCB layouts.
Technical Context
The 74LVC2G66GT,115 implements two independent bidirectional analog switches, each controlled by a dedicated active-HIGH enable input (1E, 2E). Its CMOS transmission gate architecture ensures symmetrical conduction regardless of signal polarity, with ON resistance flatness ≤1.5 Ω across the full 0–VCC voltage range.
Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V) on both enable pins, enabling reliable operation with slow-rising control signals. Overvoltage-tolerant inputs (to 5.5 V) and ESD protection (HBM >2000 V, CDM >1000 V) support robust interfacing in industrial and automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct integration into 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifters. |
| Typical ON Resistance | 6 Ω at VCC = 5 V - Minimizes signal attenuation and power loss in analog audio, sensor, and data line switching. |
| Switch Current Rating | ±32 mA - Supports driving moderate loads such as ADC inputs, op-amp feedback paths, or LED bias lines. |
| Enable Propagation Delay | 1.0–5.0 ns - Ensures sub-5 ns channel activation/deactivation for high-speed multiplexing in real-time control loops. |
| OFF-State Isolation | −46 dB at 1 MHz - Prevents crosstalk between inactive channels in multi-sensor data acquisition systems. |
| Charge Injection | 7.5 pC max at VCC = 5.5 V - Limits voltage glitch on sampled-hold nodes, critical for precision SAR ADC front-ends. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive, industrial motor drives, and outdoor IoT edge nodes. |
Pinout & Package
74LVC2G66GT,115 uses the SOT833-1 XSON8 package: 1.0 × 1.95 × 0.5 mm body, no leads, 8 solderable terminals, wettable flank profile for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1Y | First switch terminal - bidirectional I/O node; connects to source or load depending on system topology. |
| 2 | 1Z | First switch terminal - complementary I/O node; forms switch path with 1Y when 1E is HIGH. |
| 3 | 2E | Second enable input - active-HIGH control; asserts second switch independently of first channel. |
| 4 | GND | Ground reference - provides return path for switch current and digital logic; must be low-impedance. |
| 5 | 2Y | Second switch terminal - bidirectional I/O node; isolated from 2Z until 2E is asserted. |
| 6 | 2Z | Second switch terminal - completes second switch path with 2Y; shares GND with 1Y/1Z. |
| 7 | 1E | First enable input - active-HIGH control; decouples 1Y–1Z path from signal path when LOW. |
| 8 | VCC | Power supply - supplies both analog switch core and digital control logic; bypass capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports signals from GND to VCC without clipping - essential for full-scale sensor output routing. |
| Overvoltage-tolerant inputs | Withstands up to 5.5 V on all pins regardless of VCC - eliminates external clamping diodes in mixed-supply designs. |
| Low ON-resistance flatness | ≤1.5 Ω variation across 0–VCC - maintains consistent gain and THD in audio and instrumentation paths. |
| High noise immunity | Schmitt-trigger inputs with ≥0.3 V hysteresis - rejects EMI and ground bounce in noisy motor-control environments. |
| JEDEC-compliant latch-up performance | JESD78 Class I rated - guarantees immunity to destructive latch-up during transient overvoltage events. |

FAQ
What is the maximum allowable switch voltage for the 74LVC2G66GT,115?
The 74LVC2G66GT,115 supports a maximum switch voltage (VSW) of VCC + 0.5 V in both ON and OFF states, with absolute maximum rating of −0.5 V to VCC + 0.5 V. At VCC = 5.5 V, this permits analog signals up to 6.0 V peak-to-peak without damage, provided clamp current limits (±50 mA) are not exceeded.
Does the 74LVC2G66GT,115 support level translation between 1.8 V and 5 V logic domains?
Yes, the 74LVC2G66GT,115 supports bidirectional level translation: its overvoltage-tolerant inputs accept 0–5.5 V regardless of VCC, and its analog switch path passes signals rail-to-rail. When powered at 3.3 V, it reliably routes 1.8 V sensor outputs to 5 V ADC inputs or vice versa without external components.
How does the Schmitt-trigger input on the 74LVC2G66GT,115 improve system reliability?
The Schmitt-trigger action on both 1E and 2E inputs provides ≥0.3 V hysteresis, rejecting noise-induced false triggering from slow-rising control signals or ground bounce. This ensures deterministic switch activation in electrically noisy environments like motor drives or automotive power modules where the 74LVC2G66GT,115 is commonly deployed.
What is the thermal derating behavior of the 74LVC2G66GT,115 in its XSON8 package?
The 74LVC2G66GT,115 in SOT833-1 package exhibits linear total power dissipation (Ptot) derating of 3.1 mW/K above +68 °C ambient. At +100 °C, Ptot reduces from 250 mW to approximately 150 mW, requiring careful thermal design in sealed enclosures or high-power-density PCBs where the 74LVC2G66GT,115 operates near its 125 °C max junction limit.
Can the 74LVC2G66GT,115 be used in audio signal paths without introducing audible distortion?
Yes - the 74LVC2G66GT,115 achieves ≤0.005% total harmonic distortion (THD) at 4.5 V supply and 10 kHz, with ON-resistance flatness ≤1.5 Ω ensuring channel-to-channel gain matching. Its low charge injection (7.5 pC) and −46 dB isolation suppress pop/click artifacts and crosstalk, making it suitable for line-level audio routing in professional and consumer equipment.
