Product details
Overview
SN74AUC1G07YEPR from Texas Instruments is a single non-inverting buffer with open-drain output, designed for 1.65-V to 1.95-V operation and 3.6-V I/O tolerant signaling in mixed-voltage systems. It delivers 2.5 ns max propagation delay at 1.8 V, ±8-mA output drive, sub-1-V operability, and Ioff support for partial-power-down mode - used in level-shifting interfaces between 1.8-V logic and higher-voltage buses.
For engineers reviewing the SN74AUC1G07YEPR datasheet, SN74AUC1G07YEPR pinout, SN74AUC1G07YEPR application, or SN74AUC1G07YEPR equivalent, key selection criteria include open-drain compatibility with wired-OR/AND topologies, ultra-low ICC (10 µA max), 0.17-mm vs. 0.23-mm bump variants, NanoFree WCSP thermal performance (θJA = 132°C/W), and JESD 78 Class II latch-up immunity.
Technical Context
This device implements a single-channel non-inverting buffer with open-drain output stage, 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, satisfying partial-power-down requirements in multi-rail systems.
Optimized for sub-1.8-V core logic, it supports 0.8-V to 2.7-V VCC operation with VIH/VIL thresholds scaling to VCC (e.g., VIH = 0.65×VCC at 1.1–1.95 V), while maintaining 3.6-V I/O tolerance on all pins - critical for interfacing 1.8-V AUC logic with 3.3-V or 5-V peripherals without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - enables operation across battery-powered, low-voltage SoC domains including 1.2-V, 1.5-V, and 1.8-V rails. |
| tpd (max) | 2.5 ns at 1.8 V, CL = 30 pF - ensures timing-critical signal buffering in high-speed serial control paths like I²C pull-up interfaces. |
| IOL (min) | 8 mA at 1.65 V - provides sufficient sink current to drive standard 1.8-V CMOS loads and legacy 3.3-V pull-up resistors down to ~470 Ω. |
| ICC (max) | 10 µA - minimizes quiescent power in always-on system management circuits such as reset supervisors or power sequencer enable lines. |
| Ioff Support | Active at VCC = 0 V - blocks >99% of back-current flow when unpowered, protecting live 3.3-V buses during hot-swap or partial shutdown. |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements for handheld and portable equipment interfaces. |
| Package | NanoFree WCSP (YEP) - 0.23-mm solder bumps, 1.2 mm × 0.8 mm footprint, 132°C/W θJA - ideal for space-constrained wearables and sensor nodes. |
Pinout & Package
NanoFree WCSP (YEP) package: 5-terminal wafer-level chip-scale package with die-as-package construction; bottom-side solder bumps; pin 1 identified by SnPb composition marker ('1'); no internal connection on pin 3 (NC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | CMOS-compatible digital input accepting 0.8–2.7-V logic levels; must be tied to VCC or GND if unused per SCBA004. |
| 2 (GND) | Ground Reference | Primary return path for Ioff-controlled output current and supply decoupling; shared with substrate reference. |
| 3 (NC) | No Internal Connection | Unbonded pad - electrically isolated; no routing or thermal connection required on PCB. |
| 4 (Y) | Open-Drain Output | Active-low output requiring external pull-up; supports wired-OR logic and bidirectional bus arbitration. |
| 5 (VCC) | Supply Voltage | Core logic rail (0.8–2.7 V); powers internal circuitry and enables Ioff state when de-asserted. |
Key Features
| Feature | Design Value |
|---|---|
| Open-Drain Output | Enables direct connection to shared bus lines with multiple drivers; eliminates contention risk in multi-master I²C or SMBus implementations. |
| Ioff Partial-Power-Down | Prevents destructive back-current when SN74AUC1G07YEPR is unpowered but connected to live 3.3-V or 5-V signals - essential for hot-pluggable modules. |
| 3.6-V I/O Tolerance | Allows safe interface to higher-voltage peripherals without external clamping diodes or level translators - reduces BOM count and layout area. |
| NanoFree WCSP (YEP) | 0.23-mm large bump variant offers improved thermal resistance (132°C/W) and mechanical reliability over YEA/YZA small-bump versions for reflow-critical applications. |
| Sub-1-V Operability | Functional at 0.8 V VCC - supports next-generation ultra-low-power microcontrollers and energy-harvesting subsystems where supply headroom is minimal. |

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 (3.5 ns @ 1.8 V), SOT-23-5 package (2.9 mm × 1.6 mm) | Larger footprint, lower drive (±24 mA), no sub-1-V operation | Preferred when board space allows larger package and 1.65–5.5-V universal I/O tolerance is prioritized over ultra-low voltage. |
| SN74AUP1G07YEPR | Lower ICC (500 nA), slower tpd (6.1 ns @ 1.2 V), same YEP WCSP package | Better for always-on monitoring; unsuitable for >1-MHz signal paths due to propagation latency | Select when nanowatt standby power dominates timing requirements - e.g., battery-backed real-time clocks or tamper-detection circuits. |
Compared with SN74AUC1G07YEPR, SN74LVC1G07DBVR trades speed and size for broader voltage range and mature packaging, while SN74AUP1G07YEPR sacrifices speed to achieve 20× lower ICC - making each optimal for distinct low-power design priorities: high-speed sub-1.8-V signaling, general-purpose mixed-voltage buffering, or ultra-deep-sleep operation.

FAQ
What is the maximum operating voltage for SN74AUC1G07YEPR?
The SN74AUC1G07YEPR supports a supply voltage range of 0.8 V to 2.7 V, with recommended operation between 1.65 V and 1.95 V. Its I/O pins tolerate up to 3.6 V regardless of VCC, enabling safe interfacing with higher-voltage peripherals without level-shifting components - a key feature confirmed in the absolute maximum ratings and recommended operating conditions tables of SCES373L.
Does SN74AUC1G07YEPR support partial-power-down functionality?
Yes, SN74AUC1G07YEPR includes Ioff circuitry that disables output drivers when VCC = 0 V, preventing damaging current backflow from live I/O lines into the unpowered device. This behavior is explicitly specified in the datasheet's "Ioff Supports Partial-Power-Down Mode Operation" feature list and verified in the electrical characteristics table (Ioff ≤ ±10 µA at VI/VO = 2.7 V).
What package type is used for SN74AUC1G07YEPR?
SN74AUC1G07YEPR uses the NanoFree WCSP (Wafer Chip Scale Package) with YEP designation - a 5-terminal, bottom-terminal wafer-level package featuring 0.23-mm large solder bumps, 1.2 mm × 0.8 mm body size, and 132°C/W thermal resistance. This is confirmed in the ordering information table and packaging addendum of SCES373L.
Can SN74AUC1G07YEPR drive standard I²C bus pull-up resistors?
Yes, SN74AUC1G07YEPR delivers 8 mA sink current at 1.65 V, sufficient to fully pull down standard 1.8-V I²C bus configurations with 2.2-kΩ pull-ups to 0.45 V (per VOL spec). Its 2.5 ns propagation delay at 1.8 V ensures timing compliance even at 400-kHz Fast-mode speeds - validated in the switching characteristics table under CL = 30 pF.
Is SN74AUC1G07YEPR pin-compatible with other SN74AUC1G07 variants?
Yes, all SN74AUC1G07 variants - including SN74AUC1G07YEPR, SN74AUC1G07YZPR, SN74AUC1G07DBVR, and SN74AUC1G07DCKR - share identical 5-pin functional pinout (A, GND, NC, Y, VCC) and logic behavior. The YEP and YZP WCSP variants differ only in bump composition (SnPb vs. Pb-free) and thermal performance, not connectivity - confirmed in the package drawings and pin diagrams of SCES373L.
