Product details
Overview
SN74AUP1G17DBVRE4 from Texas Instruments is a low-power single Schmitt-trigger buffer IC in SOT-23-5 package, operating from 0.8 V to 3.6 V supply, delivering 5.1 ns max propagation delay at 3.3 V, 4.4 pF typical dynamic power capacitance, and 0.9 µA max ICC - designed for noise-immune signal conditioning in battery-powered portable systems.
For engineers reviewing the SN74AUP1G17DBVRE4 datasheet, SN74AUP1G17DBVRE4 pinout, SN74AUP1G17DBVRE4 application, or SN74AUP1G17DBVRE4 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.79 V min at 3 V), Ioff partial-power-down support, 3.6-V I/O tolerance for mixed-voltage interfacing, and ultra-low input capacitance (1.5 pF) enabling high-impedance node buffering without signal degradation.
Technical Context
This device implements a noninverting Schmitt-trigger buffer with hysteresis (ΔVT = 0.79 V min at VCC = 3 V), enabling robust immunity to slow-rising or noisy input transitions. Its AUP-family architecture delivers balanced CMOS push-pull output drive capable of ±4 mA at 3 V while maintaining sub-1 µA static current.
The Ioff feature actively disables outputs during power-down, limiting leakage to 0.6 µA max across –40°C to +85°C, preventing backflow current into powered-down subsystems. Input overvoltage tolerance up to 4.6 V allows safe interfacing with higher-voltage logic domains without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - supports direct connection to Li-ion battery rails, 1.2/1.8/2.5/3.3 V logic domains, and brown-out tolerant operation. |
| tpd (max) | 5.1 ns at 3.3 V, CL = 5 pF - enables reliable point-to-point timing in sub-200 MHz digital control paths. |
| ICC (max) | 0.9 µA at –40°C to +85°C - extends battery life in always-on sensor nodes and wearable standby circuits. |
| ΔVT (min) | 0.79 V at VCC = 3 V - provides >26% hysteresis ratio for noise margins exceeding 200 mV on noisy PCB traces or long cables. |
| Ioff (max) | 0.6 µA at –40°C to +85°C - ensures safe isolation during hot-swap or partial-system power gating without external disable circuitry. |
| Ci (typ) | 1.5 pF - minimizes capacitive loading on high-impedance sources such as crystal oscillator outputs or analog sensor buffers. |
| IOH/IOL | ±4 mA at VCC = 3 V - drives standard CMOS loads (e.g., multiple 74AUP inputs) without external buffering. |
Pinout & Package
SOT-23-5 (DBV) package: 1.60 mm × 2.90 mm body, 0.95 mm height, gull-wing leads, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - N.C. | No internal connection | Unbonded pad; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 - A | Input | Schmitt-trigger input with VT+ = 1.88 V / VT– = 0.88 V at 3 V - accepts slow edges down to 100 ns rise/fall without chatter. |
| 3 - GND | Ground reference | Primary return path for supply and signal currents; requires low-inductance connection to system ground plane. |
| 4 - Y | Output | Noninverting buffered output with rail-to-rail swing; drives capacitive loads ≤30 pF within spec'd tpd. |
| 5 - VCC | Positive supply | Single-supply input accepting 0.8–3.6 V; requires local 0.1 µF ceramic bypass capacitor placed ≤2 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables clean switching on slow or noisy signals (e.g., mechanical switch debouncing, RC time-constant generators) without external hysteresis components. |
| Ioff partial-power-down | Automatically places outputs in high-Z state when VCC = 0 V - eliminates backfeed risk in multi-rail systems during sequencing or fault conditions. |
| 3.6-V I/O tolerance | Allows direct interface to 3.3-V or 5-V drivers without level-shifting, simplifying mixed-voltage board design and reducing BOM count. |
| NanoStar™ packaging | Dies-as-package construction reduces parasitic inductance/capacitance - improves signal integrity and EMI performance in compact layouts. |
| Ultra-low Cpd (4.4 pF) | Minimizes dynamic power consumption at high frequencies - critical for low-duty-cycle wake-up circuits in energy-harvesting applications. |

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 (10 µA typ); no Ioff; 3.3-V only I/O tolerance. | Requires external power sequencing control; unsuitable for partial-power-down systems or sub-1.65 V rails. | Choose when interfacing legacy 5-V peripherals and board space permits larger SOT-23 footprint. |
| NC7SZ17P5X | Lower VCC min (0.9 V); higher tpd (7.5 ns @ 3.3 V); no Ioff; 5.5-V tolerant inputs; smaller SC70-5 package. | Lacks power-down isolation; less hysteresis (0.45 V @ 3.3 V); higher dynamic power (Cpd = 6.5 pF). | Prefer for ultra-compact designs where Ioff is unnecessary and 0.9-V operation suffices. |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, SN74AUP1G17DBVRE4 uniquely combines sub-1-µA static current, Ioff-enabled safe power gating, and 0.8-V operation - making it the only choice for energy-constrained, multi-rail, or hot-pluggable embedded systems requiring guaranteed signal integrity at lowest possible quiescent load.

FAQ
What is the minimum supply voltage required for reliable operation of SN74AUP1G17DBVRE4?
The SN74AUP1G17DBVRE4 operates reliably from 0.8 V to 3.6 V. At 0.8 V, it maintains functional Schmitt-trigger behavior with VT+ = 0.3 V and VT– = 0.1 V, enabling compatibility with single-cell LiFePO₄ or NiMH battery systems under deep discharge. Performance specs like tpd and drive strength scale with VCC but remain fully characterized down to 0.8 V.
Does SN74AUP1G17DBVRE4 support true bidirectional signal conditioning?
No - SN74AUP1G17DBVRE4 is a unidirectional noninverting Schmitt-trigger buffer (A → Y only). It does not support automatic direction sensing or data flow reversal. For bidirectional applications, discrete diodes or dedicated bus switches like SN74AVC2T244 must be used alongside SN74AUP1G17DBVRE4.
Can SN74AUP1G17DBVRE4 be used without a bypass capacitor?
No - a 0.1 µF ceramic capacitor placed ≤2 mm from the VCC pin is mandatory per TI's layout guidelines. Omitting it risks supply rail instability, increased ground bounce, and erratic Schmitt-trigger switching due to transient droop during output transitions, especially at VCC ≤ 1.8 V.
How does the Ioff feature behave when VCC is ramping during power-up?
SN74AUP1G17DBVRE4 enters high-Z output state whenever VCC drops below ~0.2 V. During power-up, outputs remain high-Z until VCC exceeds the internal power-on-reset threshold (~0.5 V), then transition to functional mode. This prevents false asserts on downstream logic during brown-out or soft-start sequences.
Is SN74AUP1G17DBVRE4 compatible with 5-V input signals?
Yes - SN74AUP1G17DBVRE4 inputs tolerate up to 4.6 V regardless of VCC value (per Absolute Maximum Ratings), allowing safe connection to 5-V TTL or CMOS outputs. However, output swing remains rail-to-rail (0 to VCC), so level translation to 5-V logic requires an external pull-up or dedicated translator.
