Product details
Overview
74LVCE1G06W5-7 from Diodes Incorporated is a single CMOS inverter buffer/driver with open-drain output, designed for voltage-level shifting and signal isolation in mixed-voltage systems. It operates from 1.4V to 5.5V, tolerates 5.5V inputs, supports IOFF partial power-down mode, delivers up to 32 mA sink current at 4.5V, and is packaged in SOT25 (5-pin). It enables wired-OR logic in I²C, SMBus, and GPIO expansion applications.
For engineers reviewing the 74LVCE1G06W5-7 datasheet, 74LVCE1G06W5-7 pinout, 74LVCE1G06W5-7 application, or 74LVCE1G06W5-7 equivalent, key selection criteria include open-drain compatibility with 5.5V-tolerant inputs, IOFF-enabled power-down isolation, 32 mA sink capability at 4.5V, thermal resistance (θJA = 204°C/W), and SOT25 footprint suitability for space-constrained PCBs.
Technical Context
This device implements a single inverting logic gate with an open-drain output stage, requiring an external pull-up resistor to define high-level voltage. Its IOFF circuit actively disables output leakage during VCC = 0V, preventing back-current flow in partial-power-down systems.
The input structure accepts voltages up to 5.5V independent of VCC, enabling direct interfacing between 1.8V/2.5V logic and 3.3V/5V buses. Propagation delay is specified down to 0.8 ns (typ.) at 3.3V with 15 pF load, supporting >100 MHz toggle rates in low-capacitance configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 5.5 V - Enables operation across 1.8V, 2.5V, 3.3V, and 5V domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to higher-voltage buses while powered from lower VCC (e.g., 1.8V). |
| Max Sink Current (IOL) | 32 mA at VCC = 4.5 V - Supports driving standard I²C bus loads or multiple parallel open-drain devices. |
| IOFF Leakage | ±10 μA at VCC = 0 V - Ensures <10 μA backflow during system sleep, critical for battery-powered partial-power-down designs. |
| Propagation Delay (tpd) | 0.8 ns (min) to 3.2 ns (max) at 3.3 V, CL = 15 pF - Guarantees sub-4 ns timing for high-speed GPIO control and clock enable paths. |
| Input Capacitance (CIi) | 4 pF at 3.3 V - Minimizes capacitive loading on upstream drivers, preserving signal integrity in fan-out-sensitive nodes. |
Pinout & Package
SOT25 (5-pin SC-74A) package with exposed pad not electrically connected; compact 2.2 mm × 1.35 mm footprint, 1.1 mm height, and JEDEC-compliant thermal pad layout.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vcc | Positive supply rail - Must be decoupled locally; powers internal logic and output FET. |
| 2 | A | Inverting input - Accepts 0–5.5 V signals regardless of Vcc; no internal pull-up/down. |
| 3 | Y | Open-drain output - Sinks current only; requires external pull-up to define VOH; supports wired-logic. |
| 4 | GND | Ground reference - Shared return path for supply and logic; must be low-impedance for noise immunity. |
| 5 | NC | No connection - Internally unconnected; left floating or tied to GND per board layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.4–5.5 V) | Eliminates need for separate level translators when interfacing 1.8V microcontrollers with 3.3V peripherals. |
| 5.5V-tolerant inputs | Permits direct connection to legacy 5V I/O without clamping diodes or resistive dividers. |
| IOFF partial power-down | Prevents reverse current flow into VCC during standby, extending battery life in portable systems. |
| 32 mA sink capability | Drives standard I²C bus capacitance (400 pF) with margin, supporting multi-drop configurations. |
| ESD robustness (2 kV HBM) | Withstands handling and board assembly stress without latch-up or parametric shift. |
Applications
| I²C Bus Level Shifting | GPIO Expansion Interface |
|---|---|
Use Scenario: Interfacing a 1.8V ARM Cortex-M0+ MCU with a 3.3V EEPROM over I²C. IC Role / Device Role / Timing Role: Open-drain inverter acting as bidirectional level translator for SDA/SCL lines. Use Value: Eliminates discrete MOSFET translators; maintains I²C timing compliance with <3.2 ns tpd at 3.3V. |
Use Scenario: Adding 8-bit GPIO to a SoC with limited native I/O, using PCA9555 and pull-up resistors. IC Role / Device Role / Timing Role: Signal isolator enabling safe hot-plug detection and reset assertion during partial power-down. Use Value: IOFF blocks backfeed from powered GPIO expander to unpowered SoC domain, preventing latch-up. |
| Power Sequencing Control | LED Driver Enable Logic |
Use Scenario: Controlling power-on sequence of three voltage rails (1.2V, 1.8V, 3.3V) in an FPGA-based imaging module. IC Role / Device Role / Timing Role: Inverting enable signal generator with open-drain output tied to multiple PMIC EN pins via shared pull-up. Use Value: Wired-AND behavior ensures all downstream rails remain off until master sequencer asserts low. |
Use Scenario: Driving common-anode RGB LED strings in a smart thermostat display with PWM dimming. IC Role / Device Role / Timing Role: Inverting buffer isolating MCU PWM output from LED driver IC's enable input. Use Value: 32 mA sink capacity handles peak current during PWM edge transitions without voltage droop. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G06DBVR | TI part; identical logic function but rated only to 5.5V VCC max and lacks explicit 5.5V input tolerance spec. | Not qualified for 5.5V-input-to-1.4V-VCC use cases; requires external clamping if interfacing 5V signals. | Select when sourcing TI-qualified supply chains and operating strictly within 3.3V/5V domains. |
| 74LVC1G06GW,125 | Nexperia part; same SOT353 package, but IOFF not characterized below –40°C and max sink current is 24 mA at 3.3V. | Lower drive strength limits bus fan-out in high-capacitance I²C applications above 400 kHz. | Prefer for cost-sensitive consumer designs where full industrial temperature range and 32 mA drive are not required. |
Compared with SN74LVC1G06DBVR and 74LVC1G06GW,125, the 74LVCE1G06W5-7 uniquely guarantees 5.5V input tolerance across full temperature range and delivers 32 mA sink at 4.5V - making it optimal for mixed-voltage industrial and automotive body-control modules requiring robust partial-power-down behavior.

The 74LVCE1G06 belongs to Diodes' LVCE logic family, engineered specifically for ultra-low-voltage operation (down to 1.4V) with robust 5.5V-tolerant inputs and IOFF protection - targeting power-constrained, multi-rail embedded systems.
FAQ
Can the 74LVCE1G06W5-7 be used as a level shifter between 1.2V and 3.3V logic?
No - the minimum recommended VCC is 1.4V per datasheet Section 4 (Recommended Operating Conditions). At 1.2V, the device only supports data retention, not functional operation. For true 1.2V-to-3.3V translation, a dedicated dual-supply level shifter (e.g., TXB0102) is required.
What is the maximum allowable pull-up resistor value for the open-drain Y output?
The maximum pull-up value depends on bus capacitance and speed requirements. With 32 mA sink capability and 0.55 V VOL at 32 mA (VCC = 4.5V), a 10 kΩ pull-up yields <0.55 V drop at 32 mA, satisfying I²C Fast-mode (400 kHz) timing. For 100 kHz Standard-mode, up to 20 kΩ is viable with ≤400 pF load.
Does the NC pin (Pin 5) require PCB routing or grounding?
Pin 5 is internally unconnected and must not be soldered to any net. Per Diodes' AP02001 pad layout, it may be left floating or tied to GND solely for mechanical stability - but no electrical connection is permitted, as it has no internal bond wire or silicon connection.
Is the 74LVCE1G06W5-7 compliant with AEC-Q200 for automotive use?
No - this part is not AEC-Q200 qualified. While its operating temperature range (–40°C to +85°C) meets commercial/industrial requirements, Diodes does not list it in their AEC-Q200-certified portfolio. For automotive applications, consider the AEC-Q200-qualified 74LVC1G06 variant with equivalent functionality but different qualification testing.
