Product details
Overview
SN74AUC1G07YEAR from Texas Instruments is a single non-inverting buffer with open-drain output, designed for 1.65-V to 1.95-V VCC operation and 3.6-V I/O tolerant inputs. It delivers ±8-mA output drive at 1.8 V, achieves 2.5-ns max propagation delay (tpd) at 1.8 V with 30-pF load, and supports partial-power-down via Ioff. It is used in voltage-level translation and wired-OR logic in ultra-low-voltage portable interfaces.
For engineers reviewing the SN74AUC1G07YEAR datasheet, SN74AUC1G07YEAR pinout, SN74AUC1G07YEAR application, or SN74AUC1G07YEAR equivalent, key selection criteria include open-drain compatibility with mixed-voltage buses, sub-1-V operability down to 0.8 V, Ioff-enabled power sequencing, low ICC (10 µA max), and NanoStar™ WCSP package footprint constraints.
Technical Context
This device implements a single-channel non-inverting buffer with open-drain output topology, enabling active-low wired-OR and active-high wired-AND bus configurations. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, supporting robust system-level power sequencing.
It operates across 0.8-V to 2.7-V VCC, but is optimized for 1.65–1.95 V-matching core voltages of advanced low-power SoCs and FPGAs. Input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC), ensuring reliable logic recognition across its full supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V; enables interoperability with sub-1-V logic domains and legacy 2.5-V systems |
| tpd Max | 2.5 ns at 1.8 V, CL = 30 pF; supports high-speed signal buffering in compact timing-critical paths |
| IOL Drive | ±8 mA at 1.65 V; sufficient to sink standard I²C-bus loads and drive multiple CMOS inputs |
| ICC Max | 10 µA; minimizes quiescent power in always-on battery-backed subsystems |

Pinout & Package
SN74AUC1G07YEAR uses the NanoStar™ WCSP (YEA) package-a 5-bump, 0.17-mm small bump, bottom-terminal die-scale package measuring 1.0 mm × 0.8 mm with 0.4-mm pitch. Pin 1 is identified by solder-bump composition (SnPb).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | Non-inverting digital input; accepts 0.8–3.6 V signals with rail-to-rail VIH/VIL thresholds |
| 2 (GND) | Ground | Primary reference for all internal logic and output discharge path |
| 3 (NC) | No Internal Connection | Unbonded pad; must be left floating or connected to GND per PCB design guidelines |
| 4 (VCC) | Supply | Core logic supply; powers internal circuitry and defines input thresholds and output pull-down strength |
| 5 (Y) | Open-Drain Output | Active-low output requiring external pull-up; enables wired-OR bus arbitration and voltage translation |
Key Features
| Feature | Design Value |
|---|---|
| Open-Drain Output | Enables shared-bus communication (e.g., I²C, SMBus) without contention; eliminates need for external OR-gating |
| Ioff Protection | Prevents back-current flow when VCC = 0 V, allowing hot-plug and staggered power sequencing in multi-rail systems |
| Sub-1-V Operation | Functional at 0.8 V VCC; supports next-generation ultra-low-power processors and memory interfaces |
| NanoStar™ WCSP | 1.0 mm × 0.8 mm footprint with 0.4-mm pitch; reduces board area >70% vs. SOT-23 while maintaining thermal performance (θJA = 154°C/W) |

Use Scenario: Interfacing 1.8-V accelerometer and gyroscope sensors to a 3.3-V microcontroller host over shared I²C lines. IC Role / Device Role / Timing Role: SN74AUC1G07YEAR acts as an open-drain voltage translator and bus driver, sinking current from the 3.3-V pull-up while operating from the 1.8-V sensor domain. Use Value: Eliminates need for dual-supply level shifters; maintains I²C timing compliance (tpd ≤ 2.5 ns) and supports multi-drop arbitration. |
Use Scenario: Adding a second I²C slave device to an existing bus where trace capacitance exceeds 400 pF, requiring localized signal re-driving. IC Role / Device Role / Timing Role: SN74AUC1G07YEAR buffers SDA/SCL signals between bus segments, isolating capacitance and restoring rise/fall times. Use Value: Restores signal integrity without altering protocol timing; leverages Ioff to disable during bus reset sequences. |
| Low-Power FPGA Configuration Bus | Wired-OR Power-OK Monitoring |
|
Use Scenario: Driving configuration status signals (e.g., INIT_B, DONE) from a 1.2-V FPGA core to a 3.3-V system management controller. IC Role / Device Role / Timing Role: SN74AUC1G07YEAR provides level-shifted, open-drain assertion of FPGA readiness flags with sub-1-V compatibility. Use Value: Ensures reliable handshaking across voltage domains; low ICC (10 µA) avoids loading FPGA's weak pull-ups. |
Use Scenario: Combining multiple DC/DC converter "Power Good" outputs into a single system-level "All Rails OK" signal using wired-OR logic. IC Role / Device Role / Timing Role: SN74AUC1G07YEAR serves as each rail's open-drain driver, pulling down a common pull-up only if any rail fails. Use Value: Enables fail-safe monitoring with zero additional logic gates; Ioff prevents backfeed during individual rail power-down. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Higher VCC min (1.65 V), slower tpd (3.7 ns @ 1.8 V), 32-mA drive, larger SOT-23-5 package | Less suitable for sub-1-V designs; better for 3.3-V systems needing stronger drive | Choose when higher output current or legacy SMT placement is required over size/power optimization |
| NC7SZ07P5X | Same 0.8–3.6 V range, but 4.5-ns tpd @ 1.8 V, 32-mA drive, SC-70-5 package, no Ioff | Lacks Ioff protection; not recommended for partial-power-down architectures | Choose only in fully powered systems where maximum speed is secondary to cost and availability |
Compared with SN74LVC1G07DBVR and NC7SZ07P5X, SN74AUC1G07YEAR uniquely combines sub-1-V operation, 2.5-ns speed, Ioff support, and die-scale packaging-making it optimal for space-constrained, multi-rail portable electronics requiring precise power sequencing and minimal board area.

FAQ
What is the function of SN74AUC1G07YEAR?
SN74AUC1G07YEAR is a single non-inverting buffer with open-drain output. It accepts a digital input (A), buffers it without inversion, and drives an open-drain output (Y) that requires an external pull-up resistor. This architecture enables wired-OR logic, I²C-compatible bus driving, and voltage-level translation between mismatched supply domains. Its function is defined in the datasheet's logic diagram and function table.
Does SN74AUC1G07YEAR support partial power-down?
Yes, SN74AUC1G07YEAR supports partial power-down via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables both input and output structures, limiting leakage current to ±10 µA even if input or output pins are driven to 2.7 V. This prevents damaging back-current flow during staggered power sequencing in multi-rail systems.
What package type does SN74AUC1G07YEAR use?
SN74AUC1G07YEAR uses the NanoStar™ WCSP (Wafer Chip Scale Package) with YEA marking-specifically a 5-bump, 0.17-mm small bump, bottom-terminal die-scale package measuring 1.0 mm × 0.8 mm with 0.4-mm pitch. Pin 1 is identified by SnPb solder-bump composition, and the package is leaded (SNPB) with MSL Level-1 rating.
Can SN74AUC1G07YEAR operate below 1.0 V?
Yes, SN74AUC1G07YEAR is fully specified down to 0.8 V VCC. Its recommended operating range is 0.8 V to 2.7 V, with specific optimization for 1.65–1.95 V. At 0.8 V, it maintains functional logic behavior (VIH = 0.52 V, VIL = 0.28 V) and delivers tpd ≤ 4.7 ns (CL = 15 pF), making it suitable for emerging sub-1-V processor and memory interfaces.
What is the maximum output sink current for SN74AUC1G07YEAR?
The maximum guaranteed output sink current (IOL) for SN74AUC1G07YEAR is 8 mA at VCC = 1.65 V and VOL ≤ 0.45 V, per the electrical characteristics table. At 1.8 V, it sustains 8 mA with VOL ≤ 0.45 V, and up to 9 mA at 2.3 V. Absolute maximum continuous output current is ±20 mA, but functional drive capability is validated at 8 mA under typical operating conditions.
