Product details
Overview
74LVC2G240DP,125 from Nexperia is a dual inverting buffer/line driver with 3-state outputs, designed for bidirectional signal translation and bus isolation in mixed-voltage systems. It operates from 1.65 V to 5.5 V, supports 5 V-tolerant inputs/outputs, delivers ±24 mA drive at 3.0 V, and features IOFF power-down protection. It is used in industrial control backplanes and low-power I²C/SPI level-shifting interfaces.
For engineers reviewing the 74LVC2G240DP,125 datasheet, 74LVC2G240DP,125 pinout, 74LVC2G240DP,125 application, or 74LVC2G240DP,125 equivalent, key selection criteria include 3-state enable timing (ten ≤ 4.8 ns), Schmitt-trigger input noise immunity, IOFF current < ±2 μA at VCC = 0 V, and TSSOP8 package compatibility with 0.65 mm pitch PCB layouts.
Technical Context
This device implements two independent inverting buffers, each with active-low 3-state output enable (1OE, 2OE). Output states are HIGH, LOW, or high-impedance OFF - controlled solely by OE logic level and input data (1A/2A), with no internal latching or clocking.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals. The IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow up to ±50 mA, making it suitable for partial-power-down hot-swap applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - enables direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple 74LVC inputs under worst-case conditions. |
| Propagation delay | 0.5 ns to 5.0 ns (VCC = 4.5–5.5 V) - supports >100 MHz data rates in point-to-point buffered paths. |
| IOFF leakage current | < ±2 μA at VCC = 0 V - prevents backflow damage during live insertion or system sleep mode. |
| Input hysteresis | Typ. 0.3 V at VCC = 3.3 V - rejects noise on slow-switching control lines (e.g., reset, enable) without external RC filtering. |
| ESD rating | HBM > 2000 V, CDM > 1000 V - meets industrial IEC 61000-4-2 system-level ESD immunity requirements. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-lead, 3 mm body width, 0.65 mm lead pitch, 0.5 mm lead length, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for Buffer 1 - pulls 1Y to high-Z when HIGH; must be tied LOW or driven for functional output. |
| 2 | VCC | Primary supply rail - powers both buffers and IOFF circuitry; decoupling capacitor required within 5 mm. |
| 3 | 1A | Inverting data input for Buffer 1 - Schmitt-triggered; accepts 0–5.5 V regardless of VCC level. |
| 4 | 2OE | Active-low enable for Buffer 2 - independent control allows selective bus segment isolation. |
| 5 | 2Y | Inverting output for Buffer 2 - high-Z when 2OE = HIGH; sinks/sours up to ±24 mA when enabled. |
| 6 | 1Y | Inverting output for Buffer 1 - matches 2Y electrical behavior; shares same VCC/GND reference. |
| 7 | GND | Ground reference - return path for all I/O and supply currents; requires low-inductance connection to plane. |
| 8 | 2A | Inverting data input for Buffer 2 - electrically identical to 1A; supports asynchronous dual-channel buffering. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC (1.65–5.5 V), enabling direct connection to legacy 5 V microcontrollers. |
| IOFF partial power-down | Outputs disable automatically when VCC = 0 V, limiting back-current to < ±2 μA - critical for hot-plug PCIe or USB peripheral designs. |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.3 V ensures clean switching on noisy or slow-rising control signals (e.g., mechanical switch debouncing). |
| Low dynamic power | CPD = 18 pF (enabled), 5 pF (disabled) - reduces switching power by >70% vs. standard LVC when outputs are tri-stated. |
| JEDEC-compliant | Meets JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8-B/JESD36 (2.7–3.6 V) - guarantees interoperability across voltage-tiered logic families. |
Applications
| Industrial PLC Backplane Interface | I²C Bus Level Translation |
|---|---|
|
Use Scenario: Isolating sensor node I/O lines from a central controller in a modular programmable logic controller rack. IC Role / Device Role / Timing Role: Dual inverting buffer provides direction-controlled signal conditioning and noise suppression on address/data lines between 3.3 V MCU and 5 V analog I/O modules. Use Value: Schmitt-trigger inputs reject EMI from adjacent motor drives; 3-state outputs allow shared bus arbitration without contention. |
Use Scenario: Translating SDA/SCL signals between a 1.8 V SoC and 3.3 V EEPROM in an embedded telemetry module. IC Role / Device Role / Timing Role: Inverting buffer pair acts as unidirectional level shifter with built-in voltage tolerance - no external pull-ups or biasing required. Use Value: 5 V-tolerant inputs accept 3.3 V logic highs directly; IOFF prevents leakage when SoC enters deep sleep (VCC = 0 V). |
| SPI Peripheral Isolation | Legacy Microcontroller Bus Expansion |
|
Use Scenario: Adding isolated SPI flash memory to a battery-powered edge node using a 2.5 V ARM Cortex-M0+ MCU. IC Role / Device Role / Timing Role: One buffer drives MOSI/MISO with inversion compensated in firmware; second buffer isolates chip-select line with precise enable timing (ten ≤ 4.8 ns). Use Value: Propagation delay variation < 1.5 ns across −40 °C to +125 °C ensures deterministic setup/hold margins for 20 MHz SPI. |
Use Scenario: Extending GPIO count of an aging 5 V PIC18F microcontroller using modern low-voltage peripherals. IC Role / Device Role / Timing Role: Dual inverter buffers translate 5 V control signals down to 3.3 V logic levels while driving capacitive loads up to 50 pF. Use Value: ±24 mA drive capability sustains signal integrity across 10 cm PCB traces; latch-up immunity > 250 mA protects against transient overvoltage events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual inverting buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G240DBVR | Same logic function and 3-state control, but in SOT-23-8 (VSSOP8); slightly higher ICC (max 10 μA vs. 4 μA) and lower drive (±16 mA @ 3.0 V). | Better suited for space-constrained designs where 2.3 mm body width is mandatory; less ideal for high-drive bus loading. | Select if board layout requires VSSOP8 footprint and drive demand ≤ ±16 mA. |
| 74AUP2G240GM,132 | Ultra-low-power variant (ICC < 0.5 μA typ); reduced drive (±4 mA @ 3.0 V); slower tpd (max 11.9 ns @ 1.65 V). | Optimized for always-on sensor nodes with sub-μA sleep current budgets; unsuitable for high-speed or high-load interfaces. | Select only for energy-critical battery applications where speed and drive are secondary to quiescent current. |
Compared with SN74LVC2G240DBVR and 74AUP2G240GM,132, the 74LVC2G240DP,125 offers the best balance of drive strength, speed, and industrial temperature support in TSSOP8 - making it optimal for ruggedized industrial bus interfaces requiring reliable 3-state control and mixed-voltage interoperability.

FAQ
Can the 74LVC2G240DP,125 be used as a non-inverting buffer?
No - the device implements fixed inverting logic (1A → 1Y̅, 2A → 2Y̅). To achieve non-inverting behavior, two stages must be cascaded (e.g., 1A → 1Y̅ → external inverter), adding propagation delay and board area. For native non-inverting operation, select 74LVC2G125 or 74LVC2G126 instead.
What is the maximum capacitive load the outputs can drive reliably?
The outputs are characterized up to 50 pF load capacitance per channel (per Table 10 test conditions). At 3.0 V supply and 24 mA drive, rise/fall times remain < 4 ns into 50 pF. For loads > 50 pF, add series termination or reduce slew rate via external RC to avoid ringing and timing violations.
Does the IOFF feature require external pull-downs on OE pins during power-down?
No - IOFF operates independently of OE pin state. When VCC = 0 V, outputs enter high-impedance regardless of 1OE/2OE voltage. However, OE pins should be held LOW or HIGH (not floating) during normal operation to prevent metastability-induced shoot-through current.
Is the 74LVC2G240DP,125 qualified for automotive applications?
No - this variant (74LVC2G240DP,125) is specified for −40 °C to +125 °C but is not AEC-Q100 qualified. For automotive use, specify the automotive-grade version 74LVC2G240DP-Q100, which undergoes additional stress testing and lot traceability per AEC standards.
