Product details
Overview
SN74AUC2G07YZPR from Texas Instruments is a dual buffer/driver IC with open-drain outputs, designed for 1.65-V to 1.95-V operation. It delivers ±8-mA sink/source drive at 1.8 V, achieves 2.5 ns max propagation delay, consumes only 10 µA ICC, and supports partial-power-down via Ioff. It enables wired-OR logic in low-voltage I²C, SMBus, and level-shifting interfaces.
For engineers reviewing the SN74AUC2G07YZPR datasheet, SN74AUC2G07YZPR pinout, SN74AUC2G07YZPR application, or SN74AUC2G07YZPR equivalent, key selection criteria include open-drain compatibility, sub-2-V supply tolerance, NanoFree™ DSBGA packaging, Ioff-enabled power sequencing, and 32-mA max sink capability.
Technical Context
This device implements two independent noninverting buffers, each with an open-drain output stage capable of sinking up to 32 mA. Its Ioff circuitry actively disables outputs during power-down, preventing backflow current when VCC = 0 while inputs remain biased.
It operates across 0.8 V–2.7 V VCC but is optimized for 1.65–1.95 V; input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC), and output voltage swing extends to VCC + 0.5 V, enabling mixed-mode interfacing with higher-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V; fully functional down to 0.8 V, but specified for reliable 1.65–1.95 V operation |
| Max tpd | 2.5 ns at 1.8 V, CL = 15 pF - enables high-speed signal buffering in compact low-power designs |
| IOL (1.8 V) | ±8 mA - sufficient to drive standard I²C bus loads and multiple gate inputs without external pull-ups |
| Ioff Support | Active at VCC = 0 V - blocks current flow from powered inputs to unpowered VCC rail, critical for hot-swap and multi-rail sequencing |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements without added protection circuitry |
| ICC (1.8 V) | 10 µA - ultra-low quiescent current ideal for battery-backed or always-on monitoring circuits |
| Output Type | Open-drain - allows wired-AND/OR logic, level translation, and shared-bus arbitration without contention |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G07DBVR | Higher VCC min (1.65 V), slower tpd (3.5 ns @ 1.8 V), larger SOT-23-6 package (2.9 mm × 1.6 mm) | Less suitable for space-constrained layouts; lacks sub-1-V operation and NanoFree thermal performance | Choose when legacy SOT-23 assembly infrastructure exists and 2.5 ns speed is not required. |
| NC7WZ07P6X | Same DSBGA-6 footprint, but only 1.65–5.5 V operation; no Ioff; 16 mA sink at 1.8 V | Cannot support partial-power-down; unsuitable for hot-swap or mixed-rail sequencing scenarios | Choose for cost-sensitive, single-rail 1.8-V systems where Ioff is unnecessary and 32 mA sink is not needed. |

FAQ
What is the maximum sink current supported by SN74AUC2G07YZPR?
The SN74AUC2G07YZPR supports a maximum sink current of 32 mA per output, as specified in the Absolute Maximum Ratings table. This rating applies under steady-state conditions with proper thermal management and is significantly higher than typical I²C or SMBus load requirements, allowing direct interface with LEDs, small relays, or multiple logic inputs without external drivers. The SN74AUC2G07YZPR maintains this capability across its full 0.8–2.7 V VCC range.
Does SN74AUC2G07YZPR support partial-power-down mode?
Yes, SN74AUC2G07YZPR supports partial-power-down mode via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables both outputs, blocking current flow from powered inputs (e.g., 1.8-V or 3.3-V signals) into the unpowered device. This prevents damaging back-current and ensures safe operation during power sequencing, hot-swap events, or multi-rail system sleep states. The SN74AUC2G07YZPR specifies ±10 µA Ioff at VI or VO = 2.7 V.
Can SN74AUC2G07YZPR operate below 1.0 V?
Yes, SN74AUC2G07YZPR is fully operational down to 0.8 V VCC, as confirmed in the Recommended Operating Conditions table. It is explicitly characterized for sub-1-V operation, with parameters including VOL, tpd, and VIH/VIL defined at 0.8 V. This makes the SN74AUC2G07YZPR suitable for emerging ultra-low-power applications such as energy-harvesting sensors and battery-depleted backup modes where supply voltage drops below 1.0 V.
What is the thermal resistance (θJA) of the YZP package used in SN74AUC2G07YZPR?
The YZP (DSBGA) package of SN74AUC2G07YZPR has a junction-to-ambient thermal resistance (θJA) of 123°C/W, as documented in the Absolute Maximum Ratings table. This value reflects the superior thermal performance of TI's NanoFree™ packaging, which eliminates bond wires and mold compound to reduce thermal path resistance. The SN74AUC2G07YZPR achieves lower θJA than DBV (165°C/W) and DCK (259°C/W) variants, supporting higher sustained output current in compact layouts.
Is SN74AUC2G07YZPR compatible with 3.3-V I/O systems?
Yes, SN74AUC2G07YZPR is I/O-tolerant up to 3.6 V regardless of VCC level, as stated in the Absolute Maximum Ratings and Electrical Characteristics tables. Inputs and outputs can safely accept 3.3-V signals even when VCC = 1.8 V, enabling direct connection to higher-voltage peripherals without external level shifters. This mixed-mode capability is intrinsic to the SN74AUC2G07YZPR design and does not require additional biasing or configuration.
