Product details
Overview
SN74LVC2G241DCUT 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 VCC 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 5-V logic down to lower VCC. It serves as a redriver in bus interface and memory address driver applications within compact consumer electronics.
For engineers reviewing the SN74LVC2G241DCUT datasheet, SN74LVC2G241DCUT pinout, SN74LVC2G241DCUT application, or SN74LVC2G241DCUT equivalent, key selection criteria include its VSSOP-8 (DCU) package footprint, Ioff partial-power-down capability, 3-state control via separate active-low (1OE) and active-high (2OE) enables, and guaranteed 10-µA max ICC across temperature.
Technical Context
The SN74LVC2G241DCUT implements two independent CMOS buffer channels, each with dedicated output-enable control: Gate 1 uses active-low 1OE (Pin 1), Gate 2 uses active-high 2OE (Pin 7). Its Ioff circuitry disables both outputs during power-down, blocking back-drive current and supporting live insertion.
It operates across –40°C to +125°C, accepts input voltages up to 5.5 V regardless of VCC, and maintains specified timing (e.g., tpd ≤ 4.3 ns at 3.3 V) under full recommended operating conditions. The device is characterized for bus-oriented signal integrity, including low ground bounce (VOLP < 0.8 V) and undershoot (VOHV > 2 V) at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports mixed-voltage system interfacing and single-supply operation across LVC logic families. |
| Max Propagation Delay | 4.1 ns at 3.3 V - enables high-speed signal redriving in memory address and clock distribution paths. |
| Output Drive | ±24 mA at 3.3 V - sufficient to drive 50-pF loads with fast edge rates while maintaining rail-to-rail VOH/VOL. |
| Ioff Current | ±10 µA max - ensures safe partial-power-down operation and prevents back-current flow when VCC = 0 V. |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection to 5-V legacy buses without external level-shifting components. |
| ESD Rating | ±2000 V HBM - meets industrial-grade robustness requirements for handling and board assembly. |
| Operating Temperature | –40°C to +125°C - qualified for automotive infotainment and industrial embedded environments. |
Pinout & Package
VSSOP-8 (DCU) package: 2.30 mm × 2.00 mm body, 0.5-mm lead pitch, exposed pad not present, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low output enable for Channel 1 - drives 1Y high-impedance when high; ties to VCC via pullup for power-up safety. |
| 2 | 1A | Noninverting input for Channel 1 - accepts 0–5.5 V signals; compatible with 5-V TTL and 3.3-V CMOS logic levels. |
| 3 | 2Y | Noninverting output for Channel 2 - provides ±24-mA sink/source capability at 3.3 V with controlled edge rates. |
| 4 | GND | Digital ground reference - must be connected directly to PCB ground plane with low-inductance path for noise immunity. |
| 5 | 2A | Noninverting input for Channel 2 - electrically identical to 1A; supports independent signal routing per channel. |
| 6 | 1Y | Noninverting output for Channel 1 - mirrors 1A when 1OE = low; high-impedance when 1OE = high. |
| 7 | 2OE | Active-high output enable for Channel 2 - drives 2Y high-impedance when low; ties to GND via pulldown for power-down safety. |
| 8 | VCC | Positive supply - requires local 0.1-µF ceramic bypass capacitor placed within 2 mm of pin for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction in VSSOP-8 reduces board area by >30% vs. standard SOIC-8, enabling ultra-compact layout in space-constrained devices. |
| 5.5-V tolerant inputs | Eliminates need for external level shifters when interfacing 5-V peripherals (e.g., legacy sensors, displays) to 1.8/2.5/3.3-V microcontrollers. |
| Ioff protection | Prevents damaging current flow during hot-swap or partial-power-down sequences - critical for modular systems and battery-backed subsystems. |
| Low dynamic power | 10-µA max ICC at 3.3 V enables always-on signal conditioning in low-power IoT nodes without compromising battery life. |
| Controlled output transitions | Typical VOLP < 0.8 V and VOHV > 2 V at 3.3 V suppresses ground bounce and overshoot, improving signal integrity on shared PCB traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer with 3-state output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G240DCUT | Inverting dual buffer (1A→1Y inverted); identical VSSOP-8 package, timing, and drive specs. | Required where signal polarity inversion is needed in address/data paths or bus arbitration logic. | Select SN74LVC2G240DCUT only when functional inversion is explicitly required; otherwise SN74LVC2G241DCUT provides direct signal pass-through. |
| 74LVC2G125DCUR | Noninverting dual buffer with two active-high OE inputs (vs. SN74LVC2G241DCUT's mixed OE polarity); same VSSOP-8 footprint and electrical specs. | Suitable for systems where unified OE control logic simplifies FPGA/CPLD interface design. | Choose 74LVC2G125DCUR if both OEs must be active-high; SN74LVC2G241DCUT offers flexible gating with complementary OE logic. |
Compared with SN74LVC2G241DCUT, SN74LVC2G240DCUT provides identical performance but inverted logic, while 74LVC2G125DCUR replaces mixed-polarity OE with dual active-high enables - both require layout-compatible VSSOP-8 placement but differ in control signal mapping and functional behavior.

FAQ
What is the function of Pin 1 (1OE) and Pin 7 (2OE) on the SN74LVC2G241DCUT?
Pin 1 (1OE) is the active-low output enable for Channel 1: when low, 1Y follows 1A; when high, 1Y enters high-impedance. Pin 7 (2OE) is active-high for Channel 2: when high, 2Y follows 2A; when low, 2Y is high-impedance. This asymmetric OE configuration allows independent, polarity-matched control of each buffer in mixed-logic systems. The SN74LVC2G241DCUT datasheet specifies tie-high (1OE) and tie-low (2OE) for safe power-up sequencing.
Does the SN74LVC2G241DCUT support 5-V input signals while operating at 1.8-V VCC?
Yes, the SN74LVC2G241DCUT supports input voltages up to 5.5 V regardless of VCC level - confirmed in the Recommended Operating Conditions table (VI = 0 to 5.5 V). At 1.8-V VCC, it functions as a down-translator: 5-V inputs are safely clamped and correctly interpreted as logic high, with VOH/VOL maintained relative to 1.8-V rails. This capability is intrinsic to the SN74LVC2G241DCUT's input structure and requires no external components.
What is the maximum output current the SN74LVC2G241DCUT can deliver per channel?
The SN74LVC2G241DCUT delivers ±24 mA per output at VCC = 3.3 V, as specified in the Features section and Electrical Characteristics table (IOH/IOL = ±24 mA at 3 V). At 5 V, it supports ±32 mA. These values represent absolute maximum continuous drive under recommended conditions; sustained operation above ±24 mA at 3.3 V requires thermal validation per the RθJA = 227°C/W rating for the VSSOP-8 package.
How does the Ioff feature protect the SN74LVC2G241DCUT during partial power-down?
The Ioff circuitry in the SN74LVC2G241DCUT disables all outputs when VCC = 0 V, limiting Ioff current to ±10 µA max - preventing back-current flow from powered I/O lines into the unpowered device. This protects against latch-up and damage in hot-swap or multi-rail systems. The SN74LVC2G241DCUT is fully characterized for this mode, with Ioff tested per JESD78 Class II standards.
Is the SN74LVC2G241DCUT pin-compatible with other VSSOP-8 logic buffers like the SN74LVC1G125?
No, the SN74LVC2G241DCUT is not pin-compatible with SN74LVC1G125 (single-channel, 5-pin SOT-23) or SN74LVC2G125 (dual-channel, VSSOP-8 with both OEs active-high). While all use VSSOP-8, the SN74LVC2G241DCUT has unique pin assignments: 1OE (Pin 1), 1A (Pin 2), 2Y (Pin 3), GND (Pin 4), 2A (Pin 5), 1Y (Pin 6), 2OE (Pin 7), VCC (Pin 8). Substitution requires PCB redesign due to differing OE polarity and signal routing.
