Product details
Overview
SN74AUC2G241DCUR from Texas Instruments is a dual 1-bit noninverting buffer/driver with independent 3-state outputs, designed for 1.65-V to 1.95-V operation. It delivers ±8-mA output drive at 1.8 V, achieves 1.9 ns max propagation delay (tpd), and supports sub-1-V operability down to 0.8 V - enabling high-speed, low-voltage bus interfacing in portable memory and clock distribution systems.
For engineers reviewing the SN74AUC2G241DCUR datasheet, SN74AUC2G241DCUR pinout, SN74AUC2G241DCUR application, or SN74AUC2G241DCUR equivalent, key selection criteria include Ioff-enabled partial-power-down support, 3.6-V I/O tolerance for mixed-mode signal operation, and VSSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements two independent noninverting buffers, each with dedicated output-enable (1OE, 2OE) control. Each channel passes data from A input to Y output when its OE is active low (1OE = L for Channel 1; 2OE = L for Channel 2), and enters high-impedance state when OE is inactive high.
It features Ioff circuitry that disables outputs during power-down to prevent backflow current, and operates across 0.8-V to 2.7-V VCC while being optimized for 1.65–1.95 V. Input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC), ensuring robust noise margins across supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - enables operation from ultra-low-voltage (sub-1-V) to 2.7-V systems without level shifters. |
| Max tpd @ 1.8 V | 1.9 ns - supports >500-MHz data rates in high-speed address/data bus applications. |
| Output Drive | ±8 mA @ 1.65–1.95 V - sufficient to drive 15-pF loads with fast edge rates and minimal signal degradation. |
| Ioff Support | Yes - prevents damaging current backflow when powered down, critical for hot-swap and partial-power-down systems. |
| 3.6-V I/O Tolerance | Yes - allows safe interfacing with higher-voltage logic (e.g., 3.3-V peripherals) without external protection. |
| Quiescent ICC | 10 µA @ 1.8 V - minimizes standby power in battery-powered devices such as wearables and IoT sensors. |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - exceeds JEDEC standards for robust handling in manufacturing and field use. |
Pinout & Package
VSSOP-8 (DCU) package: 2.0 mm × 1.25 mm body, 0.5-mm lead pitch, 0.9-mm max height, exposed thermal pad not present, RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | Noninverting data input for Channel 1 - must be driven to VCC or GND to avoid floating CMOS node issues. |
| 2 | 1Y (Output) | Noninverting buffered output for Channel 1 - goes high-Z when 1OE = H. |
| 3 | 2A (Input) | Noninverting data input for Channel 2 - electrically isolated from Channel 1; supports independent signal routing. |
| 4 | GND | Ground reference for both channels and internal logic - requires low-impedance connection to system ground plane. |
| 5 | 2Y (Output) | Noninverting buffered output for Channel 2 - high-Z when 2OE = H; supports bidirectional bus isolation. |
| 6 | 2OE (Output Enable) | Active-low enable for Channel 2 - tie to GND via pulldown resistor for default-enable; pullup to VCC for power-up high-Z safety. |
| 7 | 1OE (Output Enable) | Active-low enable for Channel 1 - independently controllable for staggered bus access or power-gating sequences. |
| 8 | VCC | Supply voltage input - bypass with 0.1-µF ceramic capacitor near pin to suppress switching noise and ensure stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction eliminates traditional leadframe - reduces size by >50% vs. SSOP, improves thermal resistance (θJA = 227°C/W). |
| Sub-1-V operability | Functional at 0.8 V VCC - enables direct integration into emerging ultra-low-power microcontroller domains and energy-harvesting systems. |
| 3.6-V I/O tolerance | Inputs/outputs withstand up to 3.6 V regardless of VCC - eliminates need for external voltage translators when interfacing with legacy 3.3-V logic. |
| Low dynamic power | 17 pF typical power dissipation capacitance (Cpd) at 1.8 V - reduces switching current and EMI in high-frequency clock fanout paths. |
| Latch-up immunity | Exceeds 100 mA per JESD 78 Class II - ensures robustness against transient overcurrent events in industrial environments. |

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 |
|---|---|---|---|
| SN74AUP2G241DCUR | Lower drive (±4 mA @ 1.8 V), slower tpd (3.2 ns), wider VCC range (0.8–3.6 V), lower ICC (500 nA). | Better suited for ultra-low-power always-on monitoring nodes where speed is secondary to quiescent current. | Select SN74AUP2G241DCUR only if <1-µA standby current is mandatory and 3.2-ns delay is acceptable. |
| SN74LVC2G241DCUR | Higher drive (±24 mA @ 3.3 V), 3.3-V-only optimized, no sub-1-V operation, higher ICC (10 µA @ 3.3 V). | Required when driving heavier capacitive loads (>30 pF) or interfacing exclusively with 3.3-V systems. | Choose SN74LVC2G241DCUR only for 3.3-V-only designs needing stronger drive; not suitable for 1.8-V or mixed-voltage use. |
Compared with SN74AUC2G241DCUR, SN74AUP2G241DCUR trades speed and drive strength for nanoamp-level standby current, while SN74LVC2G241DCUR sacrifices sub-1-V operation and I/O tolerance to deliver higher output current - making SN74AUC2G241DCUR the optimal balance for 1.8-V high-speed, mixed-voltage, and space-constrained applications.

FAQ
What is the minimum operating voltage for SN74AUC2G241DCUR?
The SN74AUC2G241DCUR operates down to 0.8 V VCC, with guaranteed functionality across the full 0.8-V to 2.7-V range. Its design is specifically optimized for 1.65-V to 1.95-V operation, delivering best-in-class timing and drive performance at 1.8 V. Below 0.8 V, functionality is not specified and may be unreliable.
Does SN74AUC2G241DCUR support partial-power-down operation?
Yes, SN74AUC2G241DCUR includes Ioff circuitry that disables outputs during power-down, preventing damaging current backflow when VCC = 0 V but inputs or outputs remain biased. This feature is fully characterized per JEDEC JESD78 and supports hot-swap and multi-rail system architectures.
What is the pinout configuration of SN74AUC2G241DCUR?
SN74AUC2G241DCUR uses an 8-pin VSSOP (DCU) package with the following top-view pinout: Pin 1 = 1A, Pin 2 = 1Y, Pin 3 = 2A, Pin 4 = GND, Pin 5 = 2Y, Pin 6 = 2OE, Pin 7 = 1OE, Pin 8 = VCC. Pin 1 is marked by a beveled corner on the package body.
Can SN74AUC2G241DCUR interface with 3.3-V logic systems?
Yes, SN74AUC2G241DCUR is 3.6-V I/O tolerant - its inputs and outputs can safely accept and drive up to 3.6 V regardless of VCC level. This allows direct connection to 3.3-V peripherals without level-shifting components, simplifying mixed-voltage system design.
What is the thermal resistance (θJA) of SN74AUC2G241DCUR in its VSSOP package?
The SN74AUC2G241DCUR in the VSSOP-8 (DCU) package has a junction-to-ambient thermal resistance (θJA) of 227°C/W, measured per JESD 51-7. This value assumes standard JEDEC 2-layer board conditions; actual performance improves with enhanced PCB copper pour and thermal vias.
