Product details
Overview
74LVCE1G125FZ4-7 from Diodes Incorporated is a single non-inverting buffer gate with 3-state output, designed for voltage-level shifting and bus isolation in mixed-voltage systems. It operates from 1.4V to 5.5V, tolerates 5.5V inputs, delivers ±24mA drive at 3.3V, and supports partial power-down via IOFF circuitry-enabling safe signal isolation during system sleep modes in portable electronics.
For engineers reviewing the 74LVCE1G125FZ4-7 datasheet, 74LVCE1G125FZ4-7 pinout, 74LVCE1G125FZ4-7 application, or 74LVCE1G125FZ4-7 equivalent, key selection criteria include its 1.4–5.5V supply range, 5.5V-tolerant inputs, IOFF-enabled partial power-down capability, and DFN1410 package thermal performance (θJA = 430°C/W).
Technical Context
This device implements a CMOS-based single-channel non-inverting buffer with active-low 3-state enable control (OE). Its IOFF circuit disables output leakage during VCC removal, preventing back-current flow in powered-down subsystems-a critical requirement for hot-swap and battery-backed logic domains.
Switching performance is characterized across five supply voltages (1.5V–5V), with propagation delay tPD as low as 0.4ns (CL = 15pF, VCC = 3.3V) and enable/disable times (tEN/tDIS) down to 0.8ns. Input thresholds scale with VCC per JEDEC-compliant LVC-family hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 5.5V - enables direct interface between 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage buses while powered from lower VCC (e.g., 1.8V core). |
| Output Drive Strength | ±24mA at 3.3V - sufficient to drive 50Ω transmission lines or multiple LVC inputs under heavy capacitive load. |
| IOFF Leakage Current | ±10μA max - ensures <100nW standby power in partial-power-down mode, critical for battery life in portable devices. |
| Propagation Delay | 0.4ns min / 3.0ns max (VCC = 3.3V, CL = 15pF) - supports >300MHz data rates in repeater applications. |
| ESD Protection | 2000V HBM, 200V MM - exceeds industrial IEC 61000-4-2 system-level immunity requirements for board-level robustness. |
| Operating Temperature | –40°C to +85°C - qualified for commercial and extended-temperature embedded control environments. |
Pinout & Package
74LVCE1G125FZ4-7 is packaged in a 6-pin DFN1410 (1.4mm × 1.0mm, 0.5mm pitch) with wettable flank leads. Pin 2 and Pin 5 are internally connected (GND), reducing PCB routing complexity and improving thermal dissipation through dual ground paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | CMOS-compatible input accepting 0–5.5V; threshold scales with VCC for reliable operation across supply voltages. |
| 2 (GND) | Ground Reference | Primary ground terminal; internally tied to Pin 5 for low-inductance return path and improved noise immunity. |
| 3 (Y) | 3-State Output | Non-inverting buffered output; enters high-impedance state when OE = HIGH, enabling bus sharing. |
| 4 (VCC) | Power Supply | Core supply input (1.4–5.5V); powers internal logic and output stage; decoupling required within 2mm. |
| 5 (GND) | Ground Reference | Secondary ground terminal; internally bonded to Pin 2 for enhanced thermal conduction and EMI suppression. |
| 6 (OE) | Output Enable (Active Low) | Asynchronous 3-state control; LOW enables output, HIGH forces Y into high-Z; tolerant to 5.5V regardless of VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Extended supply range (1.4–5.5V) | Eliminates need for external regulators in multi-rail systems-supports direct integration with 1.8V SoCs and 5V peripherals. |
| 5.5V-tolerant inputs | Enables seamless interfacing with legacy 5V logic or analog sensors without clamping diodes or resistive dividers. |
| IOFF partial power-down protection | Prevents destructive back-current flow when VCC is removed while other system rails remain active-essential for PCIe hot-plug and USB-C PD designs. |
| ±24mA output drive at 3.3V | Drives up to 10 LVC loads or 30pF trace capacitance at full speed, reducing need for downstream buffers in compact layouts. |
| DFN1410 wettable flank package | Supports automated optical inspection (AOI) and improves solder joint reliability in high-vibration automotive and industrial applications. |
Applications
| USB Peripheral Isolation | Low-Power Sensor Hub Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-buffer-with-3-state-output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Same 1.65–5.5V range but lacks 1.4V operation; IOFF not specified; 5-pin SOT-23 package. | Not suitable for sub-1.65V systems (e.g., 1.4V FPGA I/O banks); no guaranteed partial-power-down behavior. | Select only if operating exclusively ≥1.65V and space-constrained layout permits SOT-23 over DFN1410. |
| 74AUP1G125GW,125 | Lower ICC (0.9μA typical) and better 1.2V operation, but max VCC = 3.6V and no 5.5V input tolerance. | Cannot interface with 5V sensors or legacy peripherals; limited to ultra-low-power sub-3.3V domains. | Prefer for battery-powered IoT nodes where 1.2V operation and nanoamp ICC outweigh voltage flexibility needs. |

FAQ
What is the minimum supply voltage at which 74LVCE1G125FZ4-7 guarantees functional operation?
The device is fully specified for operation from 1.4V to 5.5V. At 1.4V, it meets all AC/DC parameters including tPD ≤6.9ns (CL=15pF), VIH/VIL thresholds, and ±3mA output drive. Data retention is supported down to 1.2V, but functional logic operation requires ≥1.4V per DS32216 Rev. 2–2 Section 4.
Can 74LVCE1G125FZ4-7 safely interface a 5V sensor output with a 1.8V microcontroller input?
Yes-the inputs tolerate up to 5.5V regardless of VCC level. When powered from 1.8V, the device accepts 5V signals on A or OE without damage or clamping, translating them to valid 1.8V-compatible logic levels at Y. No external resistors or diodes are needed.
How does the IOFF feature behave when VCC is disconnected while OE is HIGH?
When VCC = 0V and OE = HIGH (or floating), the IOFF circuit actively disables both input and output structures, limiting GND-to-VCC leakage to ≤±10μA. This prevents back-current from any live signal line (e.g., 5V bus) into the unpowered IC, satisfying IEC 61000-4-2 system-level ESD survivability requirements.
Is the DFN1410 package of 74LVCE1G125FZ4-7 compatible with standard reflow profiles for lead-free assembly?
Yes-the part is RoHS-compliant with lead-free finish and qualified for IPC/JEDEC J-STD-020D reflow profiles. Peak temperature (260°C), time above liquidus (60–150s), and ramp rates align with standard Pb-free processes. Wettable flanks support post-reflow AOI verification of solder joint integrity.
