Product details
Overview
74LVC1G06SE-7 from Diodes Incorporated is a single inverter buffer/driver with open-drain output, designed for level-shifting and signal isolation in mixed-voltage digital systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, supports IOFF partial power-down, and delivers up to 32mA sink current at 4.5V - used in notebook I/O control, peripheral enable logic, and power-down sequencing.
For engineers reviewing the 74LVC1G06SE-7 datasheet, 74LVC1G06SE-7 pinout, 74LVC1G06SE-7 application, or 74LVC1G06SE-7 equivalent, key selection criteria include open-drain drive strength, 5.5V-tolerant input compatibility, IOFF leakage performance, thermal resistance in SOT353 (371°C/W), and package footprint constraints for space-constrained PCBs.
Technical Context
This device implements a single CMOS inverter stage with an open-drain NMOS output stage, enabling wired-OR logic and bidirectional voltage translation. Its IOFF circuit actively disables both output and input paths during VCC = 0V, limiting back-current to ±200μA at 5.5V.
The input threshold scales with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V), while propagation delay ranges from 0.5ns (typ) at 5V to 6.5ns (max) at 1.8V. Output low voltage is specified down to 0.1V at 100μA and 0.55V at 32mA sink load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage buses without external clamping |
| Max Sink Current | 32mA at 4.5V - sufficient to drive LEDs, pull-down MOSFET gates, or terminate I²C lines |
| IOFF Leakage | ±200μA max at 5.5V - prevents damaging backflow when host system powers down |
| Propagation Delay | 0.5ns (typ) to 4.0ns (max) at 3.3V - supports >100MHz toggle rates in non-critical timing paths |
| ESD Protection | 2kV HBM, 1kV CDM - exceeds JEDEC JESD22-A114/A101 for board-level robustness |
| Thermal Resistance θJA | 371°C/W (SOT353) - defines maximum power dissipation (≈130mW at ΔT = 48°C rise) |
Pinout & Package
SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65mm pitch) - ultra-compact 5-pin package with exposed pad option; pin 1 marked by notch or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | Inverting logic input; 5.5V-tolerant; must be tied to VCC or GND if unused |
| 2 (GND) | Ground Reference | Primary return path for output sink current and internal biasing |
| 3 (Y) | Open-Drain Output | Active-low output requiring external pull-up; supports wired-AND/OR bus topologies |
| 4 (VCC) | Power Supply | Supplies internal logic and output driver; IOFF active when VCC = 0V |
| 5 (NC) | No Connection | Internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (1.65–5.5V) | Eliminates need for level translators between 1.8V microcontrollers and 3.3V/5V peripherals |
| IOFF partial power-down | Blocks current flow through A and Y pins during VCC ramp-down, protecting powered subsystems |
| 24mA sink at 3.3V | Directly drives standard logic inputs, small-signal MOSFETs, or indicator LEDs without buffering |
| CMOS low power | ICC ≤ 200μA max at 5.5V - suitable for always-on status signaling in battery-backed circuits |
| RoHS-compliant & halogen-free | Meets EU Directive 2011/65/EU and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G06DBVR | Same logic function and IOFF, but SOT-23-5 (3.0×2.8mm); θJA = 204°C/W | Better thermal performance in high-duty-cycle switching; larger footprint limits dense layouts | Choose when thermal headroom >100mW is required and board space permits |
| 74LVC1G06Z-7 | Identical electrical specs; SOT-553 (1.6×1.6mm, 0.5mm pitch); θJA = 231°C/W | Smaller footprint than SOT353 but lower current rating (24mA max at 3.3V vs. 32mA) | Prefer for ultra-compact designs where 24mA sink suffices and routing density is critical |
Compared with SN74LVC1G06DBVR, 74LVC1G06SE-7 trades thermal efficiency for 35% smaller area; versus 74LVC1G06Z-7, it offers +33% sink current at 4.5V while using a more manufacturable 0.65mm pitch - making it optimal for cost-sensitive, space-constrained 3.3V I/O expansion.

FAQ
Can 74LVC1G06SE-7 be used as a level shifter between 1.8V and 5V domains?
Yes - its 5.5V-tolerant inputs accept 1.8V logic highs (VIH ≥ 0.65×VCC = 1.17V), and open-drain output with external 5V pull-up generates valid 5V logic levels. Propagation delay remains under 5ns at both voltages, preserving timing integrity in bidirectional data paths like SD card interfaces.
What is the maximum continuous sink current at 2.5V supply?
At VCC = 2.5V, the datasheet specifies IOL = 8mA (max) with VOL ≤ 0.45V. This reflects the NMOS driver's RDS(on) increase at lower VGS; exceeding 8mA risks VOL rising above 0.55V, potentially violating downstream logic low thresholds in 2.5V systems.
Does the NC pin on SOT353 require grounding or can it float?
The NC pin (pin 5) is internally unconnected and must not be soldered to any net. Floating is acceptable per Diodes' layout guidance; however, grounding it improves mechanical stability and reduces EMI susceptibility in high-frequency environments - no electrical impact results from either choice.
How does IOFF behavior affect system power-down sequencing?
When VCC drops below 0.5V, IOFF activates within 100ns, disabling both input and output paths. This limits reverse current through A or Y pins to ±200μA even with 5.5V applied externally - preventing unintended power injection into unpowered rails during controlled shutdown of multi-rail systems like notebooks or servers.
