Product details
Overview
74LVCE1G125SE-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 computing and embedded peripherals.
For engineers reviewing the 74LVCE1G125SE-7 datasheet, 74LVCE1G125SE-7 pinout, 74LVCE1G125SE-7 application, or 74LVCE1G125SE-7 equivalent, this device is selected for low-voltage logic interfacing where supply flexibility, 3-state control timing (tpd ≤ 3.0 ns @ 3.3V), and robust ESD protection (2 kV HBM) are critical in space-constrained SOT353 layouts.
Technical Context
This buffer implements CMOS logic with active-low output enable (OE), enabling high-impedance state on Y when OE = HIGH. Its IOFF feature disables output leakage during VCC = 0V, preventing backflow current in partial-power-down systems.
Input voltage tolerance up to 5.5V allows direct interface with TTL and higher-voltage logic families while powered from as low as 1.4V. Propagation delay is characterized down to 1.5V (tpd ≤ 6.9 ns), and switching performance improves 30% over standard LVC at 1.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 5.5V - enables operation across battery-backed, USB-powered, and legacy 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - permits direct connection to 5V-tolerant microcontrollers without level-shifting circuitry |
| Output Drive Strength | ±24mA @ 3.3V - sufficient to drive 15pF loads with <3ns propagation delay in typical bus applications |
| IOFF Leakage Current | ±10μA max - ensures negligible current flow during power-down, critical for battery life in portable devices |
| ESD Protection | 2000V HBM, 200V MM - exceeds JEDEC JESD22-A114/A115 requirements for board-level handling reliability |
| Propagation Delay (tpd) | 0.4–3.0 ns @ VCC = 1.5–5.0V, CL = 15pF - supports high-speed data buffering in DDR clock trees and I²C repeaters |
| Power Dissipation Capacitance | 21pF @ 3.3V - quantifies dynamic power consumption for accurate thermal modeling in dense PCB layouts |
Pinout & Package
SOT353 (SC-70-5) package: 5-pin surface-mount, 1.25mm × 2.1mm footprint, 0.65mm pitch, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Non-inverting logic input; accepts 0–5.5V signals independent of VCC |
| 2 (OE) | Output Enable (active low) | Drives Y to high-impedance when HIGH; LOW enables buffered pass-through of A → Y |
| 3 (Y) | Data Output | 3-state output; sinks or sources up to ±24mA at 3.3V with rail-to-rail swing |
| 4 (Vcc) | Positive Supply | Core logic supply; range 1.4–5.5V; powers internal buffers and IOFF control circuitry |
| 5 (GND) | Ground Reference | Return path for all currents; must be low-impedance to maintain noise margin and switching integrity |
Key Features
| Feature | Design Value |
|---|---|
| Extended 1.4V–5.5V supply range | Supports dual-supply systems (e.g., 1.8V core + 3.3V I/O) without external regulators |
| 5.5V-tolerant inputs | Eliminates need for discrete level shifters when interfacing with legacy 5V peripherals |
| IOFF partial power-down | Prevents damaging back-current flow when Vcc = 0V, essential for hot-swap and battery-save modes |
| ±24mA output drive @ 3.3V | Drives multiple LS-TTL loads or 15pF transmission lines without fanout buffers |
| 2000V HBM ESD rating | Reduces field failure risk during assembly and end-user handling in consumer electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Wider operating temperature range (–40°C to +125°C vs. –40°C to +85°C); identical SOT23-5 pinout but different package footprint (SOT23 vs. SOT353) | Preferred for under-hood automotive modules requiring extended thermal stability | Select if board layout accommodates SOT23-5 and ambient temperature exceeds 85°C |
| 74AUP1G125GW,125 | Lower static current (0.9μA vs. 10μA ICC), optimized for ultra-low-power battery operation; 0.8–3.6V supply only | Better suited for always-on IoT edge nodes with multi-year battery life targets | Choose when supply is strictly ≤3.6V and quiescent current is prioritized over 5.5V input tolerance |
Compared with SN74LVC1G125DBVR and 74AUP1G125GW,125, the 74LVCE1G125SE-7 uniquely balances 5.5V input tolerance, 1.4V minimum supply, and SOT353 compactness-making it optimal for portable consumer electronics where mixed-voltage interoperability and board space are constrained.

FAQ
What is the maximum input voltage the 74LVCE1G125SE-7 can tolerate?
The device accepts input voltages up to 5.5V regardless of VCC level, enabling direct connection to 5V logic families while operating from as low as 1.4V. This eliminates external level-shifting circuitry in mixed-voltage systems such as USB-C peripherals interfacing with both 1.8V and 5V subsystems.
How does the IOFF feature function during power-down?
When VCC = 0V, the IOFF circuit disables the output driver, limiting leakage current to ±10μA even if input or output pins are biased to 5.5V. This prevents back-current flow that could disrupt adjacent powered circuits-a key requirement for hot-plug and battery-backed systems like medical wearables.
Can the 74LVCE1G125SE-7 drive a 50pF load at 3.3V?
Yes-the device maintains tpd ≤ 3.6ns with CL = 50pF at 3.3V (per DS32216 Rev. 2, page 6). Its ±24mA drive strength ensures clean signal edges into heavier capacitive loads common in PCB traces and connector stubs found in industrial I/O modules.
Is the SOT353 package RoHS-compliant and lead-free?
Yes-the 74LVCE1G125SE-7 uses lead-free terminations and "Green" molding compound (no bromine or antimony), fully compliant with EU Directive 2002/95/EC (RoHS). The SOT353 footprint matches JEDEC MO-178AB standards and supports reflow soldering per IPC-J-STD-020.
