Product details
Overview
74LVC2G241DCTRG4 from Texas Instruments is a dual 1-bit noninverting buffer/driver with independent 3-state outputs, designed for 1.65-V to 5.5-V operation. It delivers ±24-mA output drive at 3.3 V, achieves 4.1-ns max propagation delay at 3.3 V, and supports 5.5-V tolerant inputs - enabling level translation from higher-voltage logic into lower-VCC domains. It serves as a bus-oriented redriver in compact consumer audio/video interfaces.
For engineers reviewing the 74LVC2G241DCTRG4 datasheet, 74LVC2G241DCTRG4 pinout, 74LVC2G241DCTRG4 application, or 74LVC2G241DCTRG4 equivalent, key selection criteria include Ioff-enabled partial-power-down protection, NanoFree™ SM8 package footprint (2.95 mm × 2.80 mm), guaranteed 3-state isolation during power sequencing, and verified 10-µA max ICC across temperature.
Technical Context
The 74LVC2G241DCTRG4 implements two independent CMOS buffer channels, each with active-low (1OE) and active-high (2OE) output-enable controls. Its Ioff circuitry disables both outputs when VCC = 0 V, blocking back-drive current up to ±10 µA and supporting live insertion in hot-swap systems.
Each channel operates with rail-to-rail output swing (VOH ≥ VCC – 0.1 V, VOL ≤ 0.55 V at 24 mA), exhibits input overvoltage tolerance to 5.5 V regardless of VCC setting, and maintains stable timing performance across –40°C to 125°C with tpd ≤ 4.3 ns at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| Max Propagation Delay | 4.1 ns at 3.3 V - ensures sub-5-ns signal integrity for high-speed bus redriving |
| Output Drive Strength | ±24 mA at 3.3 V - sustains robust signal integrity into 50-pF loads with minimal edge degradation |
| Ioff Current | ±10 µA max - prevents damaging back-current flow during partial power-down or hot-plug events |
| Input Voltage Tolerance | Up to 5.5 V - allows direct interfacing with 5-V legacy peripherals without external level shifters |
| ESD Protection | ±2000-V HBM - meets industrial-grade handling requirements without additional protection circuitry |
| ICC (Quiescent) | 10 µA max - minimizes standby power in battery-sensitive portable media applications |
Pinout & Package
74LVC2G241DCTRG4 uses the SM8 (8-pin Small Outline Package) with nominal body size 2.95 mm × 2.80 mm and 0.65-mm lead pitch. The package is RoHS-compliant, moisture sensitivity level 1, and rated for –40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low output enable for Channel 1 - drives 1Y high-impedance when logic high |
| 2 | 1A | Noninverting input for Channel 1 - passes signal directly to 1Y when 1OE = low |
| 3 | 2Y | Noninverting output for Channel 2 - reflects 2A state when 2OE = high |
| 4 | GND | Ground reference - must be connected to system common plane for noise immunity |
| 5 | 2A | Noninverting input for Channel 2 - isolated from Channel 1 for independent bus control |
| 6 | 1Y | Noninverting output for Channel 1 - provides buffered, 3-state output with ±24-mA drive |
| 7 | 2OE | Active-high output enable for Channel 2 - asserts 2Y only when logic high |
| 8 | VCC | Power supply - supplies internal logic and output drivers; requires local 0.1-µF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction reduces footprint by >50% vs. standard SOIC-8, enabling ultra-dense PCB layouts |
| Ioff partial-power-down support | Enables safe insertion into powered-backplane systems without risk of latch-up or back-drive damage |
| 5.5-V tolerant inputs | Eliminates need for external level translators when interfacing 5-V sensors or legacy controllers to 3.3-V buses |
| Guaranteed 3-state isolation | IOZ ≤ 10 µA at 3.6 V ensures negligible leakage between enabled/disabled channels on shared data lines |
| Low ground bounce (VOLP) | <0.8 V typical at 3.3 V - suppresses switching noise that could corrupt adjacent low-voltage analog circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G240DCTRG4 | Inverting output polarity per channel; identical VCC range, drive strength, and Ioff spec | Requires logic inversion in firmware or upstream logic; unsuitable where signal polarity must be preserved | Select only if system-level signal inversion is acceptable and pin-compatible layout reuse is prioritized |
| 74LVC2G125DCTRG4 | Single-enable architecture (shared OE); lacks independent 1OE/2OE control; same SM8 package | Cannot support asymmetric channel enable timing - limits use in time-multiplexed bus architectures | Prefer when cost reduction outweighs need for independent channel gating, e.g., simple unidirectional repeaters |
Compared with SN74LVC2G240DCTRG4 and 74LVC2G125DCTRG4, the 74LVC2G241DCTRG4 uniquely provides noninverting logic with fully independent output-enable controls - essential for applications requiring precise per-channel bus arbitration without polarity inversion or shared-enable constraints.

FAQ
What is the maximum operating temperature for the 74LVC2G241DCTRG4?
The 74LVC2G241DCTRG4 is fully specified for operation from –40°C to 125°C ambient temperature. This extended range is validated across all electrical parameters including propagation delay, output drive, and Ioff leakage, making it suitable for sealed industrial enclosures and automotive cabin environments where thermal management is constrained.
Does the 74LVC2G241DCTRG4 support level translation between different supply voltages?
Yes, the 74LVC2G241DCTRG4 supports down-translation: its inputs tolerate up to 5.5 V regardless of VCC setting, allowing connection to 5-V logic while operating from 1.65–3.3 V supplies. However, it does not perform up-translation - outputs swing only between GND and the applied VCC, not beyond it.
How does the Ioff feature protect the 74LVC2G241DCTRG4 during partial power-down?
The Ioff circuitry in the 74LVC2G241DCTRG4 actively disables all output buffers when VCC = 0 V, limiting current flow through the device to ±10 µA maximum. This prevents back-driving of powered rails by externally driven signals - a critical safeguard during hot-swap events or staged power sequencing in modular systems.
What is the recommended bypass capacitor for the 74LVC2G241DCTRG4 VCC pin?
A 0.1-µF ceramic capacitor placed as close as possible to the VCC pin (Pin 8) is recommended for the 74LVC2G241DCTRG4. TI specifies this value to suppress high-frequency switching noise generated by the ±24-mA output drivers, ensuring stable operation under dynamic load conditions across the full 1.65–5.5-V supply range.
Can the 74LVC2G241DCTRG4 replace the 74LVC2G240DCTRG4 in an existing design?
No - the 74LVC2G241DCTRG4 has noninverting outputs, whereas the 74LVC2G240DCTRG4 is inverting. Swapping them would invert logic states on both channels, causing functional failure unless compensated by upstream logic inversion. Pinout and DC specs are identical, but polarity mismatch makes them non-interchangeable without design revision.
