Product details
Overview
SN74AUC1G17YEPR from Texas Instruments is a single Schmitt-trigger buffer IC designed for sub-1-V to 2.7-V operation, optimized at 1.8 V with 2.4 ns max propagation delay, ±8-mA output drive, and Ioff partial-power-down support. It serves as a noise-immune signal conditioner in high-speed digital interfaces of portable audio and embedded computing systems.
For engineers reviewing the SN74AUC1G17YEPR datasheet, SN74AUC1G17YEPR pinout, SN74AUC1G17YEPR application, or SN74AUC1G17YEPR equivalent, key selection criteria include its 1.65–1.95-V nominal VCC range, hysteresis-enabled input threshold separation (VT+ = 1.16 V, VT– = 0.62 V at 1.65 V), 3.6-V I/O tolerance, and NanoFree™ DSBGA packaging for ultra-compact PCB layouts.
Technical Context
The SN74AUC1G17YEPR implements a noninverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds-VT+ = 1.16 V and VT– = 0.62 V at 1.65 V VCC-enabling robust noise rejection on slow or noisy signals. Its Ioff circuitry actively disables outputs during power-down, preventing back-drive current flow.
It operates across 0.8 V to 2.7 V VCC, supports 3.6-V tolerant I/O for mixed-voltage domain interfacing, and delivers 2.4 ns tpd at 1.8 V with CL = 30 pF. The device meets JESD 78 Class II latch-up (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - enables direct integration into sub-1-V logic rails and legacy 1.8-V/2.5-V systems |
| Max Propagation Delay | 2.4 ns at 1.8 V, CL = 30 pF - supports >400-MHz signal conditioning in timing-critical paths |
| Output Drive | ±8 mA at 1.65 V - sufficient to drive 50-Ω transmission lines or fan-out to ≥10 AUC-series inputs |
| Hysteresis ΔVT | 0.54 V at 1.65 V (VT+ – VT–) - rejects up to 540 mV of input noise without false triggering |
| Ioff Current | ±10 µA at VI/VO = 2.7 V - ensures safe isolation during partial power-down in multi-rail systems |
| ESD Rating | 2000-V HBM - meets industrial handling requirements without external protection diodes |
| ICC (Max) | 10 µA - enables always-on signal buffering in battery-powered devices with negligible quiescent load |
Pinout & Package
SN74AUC1G17YEPR uses the 5-pin DSBGA (YZP) package (1.75 mm × 1.25 mm, 0.5 mm max height), featuring die-size ball grid array construction where the silicon die serves as the mechanical package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Logic input | Single CMOS-compatible input accepting 0–3.6 V; Schmitt-triggered for noise immunity |
| Y | Buffered output | Noninverting, rail-to-rail CMOS output with ±8-mA drive capability at 1.65 V |
| VCC | Positive supply | Primary power pin; supports 0.8–2.7 V operation and 3.6-V I/O tolerance |
| GND | Ground reference | Return path for all internal logic and I/O; must be low-impedance for stable hysteresis |
| NC | No internal connection | Unbonded pad; electrically isolated and must not be connected to any net |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.54-V hysteresis at 1.65 V to eliminate chatter on slow-rising/falling signals in noisy environments |
| Ioff partial-power-down | Disables outputs when VCC = 0 V, blocking back-drive current and enabling hot-insertion in multi-supply systems |
| NanoFree™ DSBGA | 1.75 mm × 1.25 mm footprint eliminates leadframe, reduces parasitic inductance, and enables <0.5-mm board thickness designs |
| 3.6-V I/O tolerance | Allows interface with 3.3-V or 2.5-V peripherals while powered from 1.8-V rails-no level shifters required |
| Sub-1-V operability | Functional down to 0.8 V VCC-supports emerging ultra-low-power microcontrollers and energy-harvesting subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Wider VCC range (1.65–5.5 V); higher ICC (max 10 µA vs. 10 µA same), but no sub-1-V operation | Preferred for 3.3-V/5-V legacy systems; unsuitable for <1.2-V rails | Select when interfacing with 5-V peripherals or requiring higher drive strength (±24 mA at 3.3 V) |
| 74AUP1G17GW,125 | NXP variant with identical 0.8–2.7-V range and 2.5 ns tpd, but different ESD rating (1500-V HBM) and no Ioff | Lacks Ioff-requires external isolation in partial-power-down designs | Choose only if TI supply chain constraints exist; verify Ioff absence does not compromise system-level power sequencing |
Compared with SN74LVC1G17DBVR and 74AUP1G17GW,125, the SN74AUC1G17YEPR uniquely combines sub-1-V operation, integrated Ioff, and NanoFree™ packaging-making it the sole option for space-constrained, multi-rail, battery-operated designs requiring guaranteed zero-backdrive behavior.

FAQ
What is the minimum operating voltage for SN74AUC1G17YEPR?
The SN74AUC1G17YEPR is fully specified down to 0.8 V VCC and functions reliably in sub-1-V domains. At 0.8 V, it maintains defined logic thresholds (VT+ = 0.5 V, VT– = 0.3 V) and delivers 0.7-mA output drive-enabling direct use with emerging ultra-low-power MCUs and energy-harvesting circuits. This capability is confirmed in Section 6.3 of the official SN74AUC1G17 datasheet.
Does SN74AUC1G17YEPR support Ioff, and how does it behave during power-down?
Yes, SN74AUC1G17YEPR features Ioff circuitry that actively disables both input and output terminals when VCC = 0 V. Measured Ioff is ±10 µA at VI/VO = 2.7 V, preventing damaging back-current flow into powered-down sections. This behavior is validated in Section 6.5 Electrical Characteristics and enables safe partial-power-down in multi-rail systems without external isolation components.
What is the hysteresis voltage (ΔVT) of SN74AUC1G17YEPR at 1.65 V VCC?
At 1.65 V VCC, the SN74AUC1G17YEPR exhibits VT+ = 0.79 V and VT– = 0.39 V, yielding a hysteresis of ΔVT = 0.40 V. This value is explicitly listed in Table 6-5 (Electrical Characteristics) of the SN74AUC1G17 datasheet and provides robust immunity against noise spikes up to 400 mV on the input signal path.
Can SN74AUC1G17YEPR interface directly with 3.3-V logic while powered from 1.8 V?
Yes. SN74AUC1G17YEPR has 3.6-V I/O tolerance, meaning its inputs and outputs safely accept and drive up to 3.6 V regardless of VCC (0.8–2.7 V). When powered from 1.8 V, it can directly receive 3.3-V signals and drive 3.3-V loads-eliminating external level shifters in mixed-voltage systems such as SSDs and embedded PCs.
What package type and dimensions does SN74AUC1G17YEPR use?
SN74AUC1G17YEPR uses the YZP (DSBGA) package: a 5-ball, die-size ball grid array measuring 1.75 mm × 1.25 mm with 0.5 mm maximum height. Pin 1 is located at corner A1 (bottom view), and the package employs solder balls-not leads-enabling ultra-thin, high-density PCB assembly. Mechanical details are documented in TI's YZP0005 package outline drawing.
