Product details
Overview
SN74AUC1G240YEPR from Texas Instruments is a single noninverting buffer/driver with 3-state output, designed for 1.65-V to 1.95-V VCC operation. It delivers ±8-mA drive at 1.8 V, achieves 2.5-ns max propagation delay, and supports mixed-mode signal operation with 3.6-V I/O tolerance - used in low-voltage logic interfacing between FPGA I/O banks and memory subsystems.
For engineers reviewing the SN74AUC1G240YEPR datasheet, SN74AUC1G240YEPR pinout, SN74AUC1G240YEPR application, or SN74AUC1G240YEPR equivalent, key selection criteria include sub-1-V operability, Ioff-enabled partial-power-down support, ±10-µA max Ioff, 2.5-ns tpd at 1.8 V, and NanoFree™ WCSP package compatibility with space-constrained portable designs.
Technical Context
This device implements a single-channel noninverting buffer with active-low 3-state control (OE high disables output). Its logic diagram confirms direct A→Y path with OE gating the output driver stage, enabling high-impedance state independent of input level.
Designed for ultra-low-voltage systems, it operates across 0.8-V to 2.7-V VCC, but is optimized for 1.65–1.95 V; Ioff circuitry prevents backflow current during partial power-down, and ESD protection exceeds JESD 22 standards (2000-V HBM, 200-V MM, 1000-V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - enables operation in sub-1-V domains and compatibility with 1.2-V/1.5-V/1.8-V supply rails |
| Max tpd | 2.5 ns at 1.8 V, CL = 30 pF - ensures timing-critical signal buffering in high-speed digital interfaces |
| Output Drive | ±8 mA at 1.8 V - sufficient to drive 15-pF loads across PCB traces without external termination |
| Ioff | ±10 µA at VI/VO = 2.7 V - guarantees safe isolation during system power sequencing |
| ICC Max | 10 µA - minimizes quiescent power in always-on logic monitoring paths |
| I/O Tolerance | 3.6-V - allows interfacing with higher-voltage peripherals without level shifters |
| ESD Rating | 2000-V HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
NanoFree™ WCSP (YZP) 5-pin die-size package: 0.87 mm × 0.87 mm, 0.23-mm large bump, bottom-side solder balls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A (Input) | Noninverting data input - must be held at VCC or GND when unused to prevent floating CMOS node |
| 2 | OE (Active-Low Enable) | 3-state control input - tie to VCC via pullup resistor for power-up high-Z safety |
| 3 | GND | Ground reference - shared return for input/output signals and internal biasing |
| 4 | Y (Output) | Buffered noninverting output - enters high-impedance state when OE = high |
| 5 | VCC | Supply voltage - powers internal logic and output driver; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ WCSP packaging | Die-as-package construction reduces footprint to 0.76 mm² - eliminates wirebond and mold compound for minimal height and thermal resistance |
| Ioff partial-power-down support | Enables safe hot-insertion and multi-rail sequencing by blocking reverse current flow when VCC = 0 |
| Sub-1-V operability | Functional down to 0.8 V VCC - supports emerging ultra-low-power sensor hub and wearables architectures |
| 3.6-V I/O tolerance | Permits direct connection to 3.3-V GPIOs or legacy peripherals without level translation components |
| 2.5-ns max tpd at 1.8 V | Meets setup/hold timing for 300+ MHz clock domains in portable SoC interconnects |
Applications
| Mobile Baseband Interface | FPGA I/O Expansion |
|---|---|
Use Scenario: Level-shifting and fanout buffering between 1.8-V application processor and 3.3-V peripheral UART/SDIO lines in smartphones. IC Role / Device Role / Timing Role: Noninverting 3-state buffer isolating voltage domains while preserving signal integrity and timing margins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUC1G125YEPR | Inverting buffer (A→Y̅), identical electrical specs and package | Requires logic inversion in signal path; unsuitable where polarity must be preserved | Select only if system-level logic requires inversion - otherwise SN74AUC1G240YEPR maintains signal polarity |
| SN74LVC1G125DBVR | SOT-23-5 package (DBV), 1.65–5.5-V VCC, 32-mA drive at 3.3 V, 4.5-ns tpd | Larger footprint, higher drive, slower speed, wider voltage range - suited for general-purpose 3.3-V systems | Choose for cost-sensitive 3.3-V designs where NanoFree™ size isn't critical and higher drive is needed |
Compared with SN74AUC1G240YEPR, SN74AUC1G125YEPR provides identical performance in an inverting configuration, while SN74LVC1G125DBVR trades NanoFree™ miniaturization and 2.5-ns speed for broader voltage range and higher output current in a standard SOT-23 package.

FAQ
What is the minimum supply voltage at which SN74AUC1G240YEPR remains functional?
The SN74AUC1G240YEPR operates down to 0.8 V VCC, as specified in the Recommended Operating Conditions table. At this voltage, it maintains valid logic thresholds (VIL ≤ 0 V, VIH ≥ 0.65×VCC) and delivers measurable output drive. The SN74AUC1G240YEPR is explicitly characterized for sub-1-V use in portable and energy-harvesting systems.
Does SN74AUC1G240YEPR support hot-plug or partial-power-down operation?
Yes, SN74AUC1G240YEPR includes Ioff circuitry that disables outputs and limits current to ±10 µA when VI or VO exceeds powered-down VCC. This feature enables safe hot-insertion into live backplanes and supports controlled power sequencing in multi-rail systems - a core design requirement validated per JESD 78 Class II latch-up testing.
What is the maximum output drive capability of SN74AUC1G240YEPR at 1.8 V?
At 1.8 V VCC, SN74AUC1G240YEPR delivers ±8 mA into resistive loads, as confirmed in the Electrical Characteristics table under IOH and IOL test conditions. This drive strength supports driving 15-pF loads with <2.5-ns propagation delay and meets JEDEC-compliant waveform fidelity for 1.8-V LVTTL-compatible interfaces.
Is SN74AUC1G240YEPR pin-compatible with other 5-pin logic buffers in the same package?
SN74AUC1G240YEPR uses the YZP (NanoFree™ WCSP) 5-ball layout with standardized pin 1 indexing (Q3 quadrant). While pin functions (A, OE, GND, Y, VCC) match industry-standard 5-pin buffer topology, direct pin-to-pin replacement requires verification of identical ball pitch (0.4 mm), solder mask opening, and thermal pad design - TI's YZP footprint is not mechanically interchangeable with SOT-23 or SC-70 packages.
How does the NanoFree™ package of SN74AUC1G240YEPR impact thermal performance?
SN74AUC1G240YEPR in YZP package achieves θJA = 132°C/W, significantly lower than DBV (206°C/W) or DCK (252°C/W) variants due to direct die-to-PCB thermal conduction. This enables higher sustained output current in thermally constrained spaces like stacked modules or sealed wearables - verified via JESD 51-7 measurement methodology.
