Product details
Overview
74LVCV2G66GD,125 from NXP Semiconductors is a dual overvoltage-tolerant bilateral analog/digital switch IC operating from 2.3 V to 5.5 V supply, featuring 7.3 Ω typical ON resistance at 5.0 V, ±32 mA switch current capability, and −40 °C to +125 °C temperature range. It enables signal routing in portable battery-powered systems where level-shifting and low-power control are critical.
For engineers reviewing the 74LVCV2G66GD,125 datasheet, 74LVCV2G66GD,125 pinout, 74LVCV2G66GD,125 application, or 74LVCV2G66GD,125 equivalent, key selection criteria include overvoltage tolerance up to 5.5 V independent of VCC, ultra-low enable input current (≤0.1 µA), sub-1 ns propagation delay at 5 V, and XSON8 package compatibility with high-density PCB layouts.
Technical Context
The 74LVCV2G66GD,125 implements two independent SPST switches with active-HIGH enable inputs (1E, 2E) and overvoltage-tolerant bidirectional terminals (1Z/1Y, 2Z/2Y), allowing signals up to 5.5 V to pass regardless of VCC level. Each switch supports rail-to-rail analog/digital signal handling with flat ON resistance (<3 Ω variation across VSW).
Its CMOS Si-gate architecture delivers latch-up immunity exceeding 250 mA and static ESD protection per JESD22-A114 (±2 kV HBM). The device operates without external current-limiting resistors on enable lines due to <5 µA typical ΔICC at VCC − 0.6 V, making it suitable for direct interfacing with low-voltage logic controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.3 V to 5.5 V - supports single-supply operation across 3.3 V and 5 V logic domains without level shifters. |
| ON Resistance (Typ) | 7.3 Ω at VCC = 5.0 V - ensures minimal insertion loss and voltage drop for precision analog switching. |
| Switch Current Rating | ±32 mA - handles audio, sensor, and digital bus signals without derating in industrial ambient conditions. |
| Overvoltage Tolerance | Up to 5.5 V on Z/Y pins independent of VCC - enables safe interfacing with legacy 5 V peripherals while powered from 2.5 V or 3.3 V rails. |
| Propagation Delay | 0.2 ns (typ) at VCC = 5.0 V - preserves signal integrity for high-speed digital multiplexing up to 100 MHz. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and extended-range IoT edge nodes. |
| Enable Input Leakage | ±0.1 µA (max) - eliminates need for series current-limiting resistors in battery-critical portable designs. |
Pinout & Package
XSON8 package (SOT996-2): plastic extremely thin small outline package, no leads, 8 terminals, body size 3 mm × 2 mm × 0.5 mm, pin 1 indicator located on lower-left corner below marking code Y66.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Z | Independent I/O (overvoltage tolerant) | Bidirectional analog/digital path for first switch; accepts up to 5.5 V regardless of VCC value. |
| 1Y | Independent I/O | Complementary terminal to 1Z; forms fully symmetric SPST switch with matched RON characteristics. |
| 2E | Enable input (active HIGH) | Controls second switch; logic HIGH enables conduction; ultra-low leakage avoids battery drain. |

| 2Z | Independent I/O (overvoltage tolerant) | Second overvoltage-tolerant switch path; electrically isolated from 1Z/1Y with >55 dB crosstalk suppression. |
| 2Y | Independent I/O | Complementary terminal to 2Z; shares same RON flatness and charge injection (<0.0035 pC) as 1Y. |
| 1E | Enable input (active HIGH) | Controls first switch; compatible with 1.8 V, 2.5 V, 3.3 V, and 5 V logic thresholds per VIH/VIL specs. |
| VCC | Supply voltage | Power rail for internal logic and switch bias; decoupling capacitor (100 nF) required within 3 mm for stable 210 MHz f(−3dB) performance. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum overvoltage rating for the 74LVCV2G66GD,125 switch terminals?
The 74LVCV2G66GD,125 switch terminals (1Z, 1Y, 2Z, 2Y) tolerate voltages up to 5.5 V independent of VCC level. This allows safe interfacing with 5 V peripherals even when VCC is as low as 2.3 V, eliminating external clamping diodes in mixed-voltage systems.
Does the 74LVCV2G66GD,125 require external current-limiting resistors on its enable inputs?
No. The 74LVCV2G66GD,125 features ultra-low enable input leakage (≤0.1 µA typical) and does not require external current-limiting resistors-even when driven by 1.8 V logic controlling a 5 V VCC rail. This reduces BOM count and improves reliability in battery-powered designs.
What is the typical ON resistance of the 74LVCV2G66GD,125 at 3.3 V supply?
At VCC = 3.3 V, the 74LVCV2G66GD,125 exhibits 7.5 Ω typical ON resistance (RON(rail)) under 24 mA load. This value remains stable across temperature (−40 °C to +125 °C) and input voltage, ensuring predictable analog signal attenuation.
Can the 74LVCV2G66GD,125 be used for high-frequency analog signal routing?
Yes. The 74LVCV2G66GD,125 delivers a −3 dB bandwidth of 210 MHz at VCC = 4.5 V with RL = 600 Ω and CL = 50 pF. Its low charge injection (<0.0035 pC) and crosstalk (<−55 dB) make it suitable for audio, video, and USB 1.1 signal paths.
What package type is used for the 74LVCV2G66GD,125 and what are its dimensions?
The 74LVCV2G66GD,125 uses the XSON8 package (SOT996-2): leadless, 3 mm × 2 mm × 0.5 mm body size with 8 terminals. Pin 1 is marked in the lower-left corner below the Y66 top-side marking, supporting fine-pitch automated assembly.
