Product details
Overview
SN74AUP1G17DBVRG4 from Texas Instruments is a low-power single Schmitt-trigger buffer IC in SOT-23-5 package, operating across 0.8 V to 3.6 V supply range, delivering 5.1 ns max propagation delay at 3.3 V, 0.9 µA max ICC, and 4.4 pF typical Cpd - used for noise-immune signal conditioning in portable battery-powered systems.
For engineers reviewing the SN74AUP1G17DBVRG4 datasheet, SN74AUP1G17DBVRG4 pinout, SN74AUP1G17DBVRG4 application, or SN74AUP1G17DBVRG4 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.79 V min at 3 V), Ioff support for partial power-down, 3.6-V I/O tolerance, and ultra-low input capacitance (1.5 pF).
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 signals. Its Ioff circuitry ensures outputs enter high-impedance state when VCC = 0 V, preventing back-current flow during partial power-down sequences.
The AUP family uses advanced CMOS process to achieve sub-1 µA static current across full 0.8–3.6 V VCC range while maintaining rail-to-rail output swing and 3.6-V tolerant inputs - optimized for point-to-point interfacing in mixed-voltage domains without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - supports direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| tpd (max) | 5.1 ns at 3.3 V, CL = 5 pF - enables timing-critical signal buffering up to ~100 MHz edge rates |
| ICC (max) | 0.9 µA at TA = –40°C to +85°C - extends battery life in always-on sensor nodes and wearables |
| Cpd (typ) | 4.4 pF at 3.3 V - minimizes dynamic switching power in high-frequency clock/data paths |
| Input Hysteresis ΔVT | 0.79 V min at VCC = 3 V - rejects >100 mV of input noise without false triggering |
| Ioff (max) | 0.6 µA at TA = –40°C to +85°C - isolates powered-down sections in multi-rail systems |
| VI/O Tolerance | 3.6 V absolute max - allows safe connection to 3.3-V buses even when VCC = 1.8 V |
Pinout & Package
SOT-23-5 (DBV) package: 1.60 mm × 2.90 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - N.C. | No internal connection | Must be left unconnected; no routing or pull-up/pull-down required |
| 2 - A | Input | Schmitt-trigger input with VT+ = 1.88 V / VT– = 0.88 V at VCC = 3 V |
| 3 - GND | Ground reference | Primary return path for supply and signal currents; requires low-inductance PCB connection |
| 4 - Y | Output | CMOS push-pull output capable of ±4 mA drive at VCC = 3 V |
| 5 - VCC | Positive supply | Accepts 0.8–3.6 V; requires local 0.1 µF bypass capacitor placed ≤2 mm from pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable switching on slow or noisy signals (e.g., mechanical switch debouncing, RC reset timing) |
| Ioff partial-power-down | Prevents back-current damage when VCC = 0 V while other system rails remain active |
| Ultra-low ICC | 0.9 µA max over full temperature range - eliminates need for enable control in ultra-low-power sleep modes |
| 3.6-V I/O tolerant | Allows interoperability between 1.8-V core logic and 3.3-V peripherals without external level translators |
| Low input capacitance | 1.5 pF typical - minimizes loading on high-impedance sources such as crystal oscillators or sensor outputs |

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 | Higher ICC (10 µA typ), wider VCC range (1.65–5.5 V), no Ioff, 5.5-V tolerant I/O | Requires external power sequencing control; unsuitable for true partial-power-down systems | Choose when interfacing with 5-V legacy peripherals and higher-speed operation (>150 MHz) is needed |
| NC7SZ17P5X | Lower drive (±2.6 mA), smaller SC70-5 package (1.25 × 2.00 mm), no Ioff, 5.5-V tolerant I/O | Lacks Ioff protection; not rated for mixed-rail isolation during power-down | Choose when board space is constrained and full power-down isolation is not required |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, SN74AUP1G17DBVRG4 uniquely delivers sub-1 µA static current with guaranteed Ioff behavior - making it the only option for battery-powered systems requiring zero-leakage isolation during deep-sleep states.

FAQ
What is the maximum propagation delay of SN74AUP1G17DBVRG4 at 3.3 V?
The maximum propagation delay (tpd) of SN74AUP1G17DBVRG4 is 5.1 ns at VCC = 3.3 V, CL = 5 pF, and TA = –40°C to +85°C. This value is specified in the Switching Characteristics table under Section 6.6 of the official TI datasheet SCES579J. The delay remains consistent across temperature and load conditions within the recommended operating range, making SN74AUP1G17DBVRG4 suitable for timing-critical signal conditioning in portable electronics.
Does SN74AUP1G17DBVRG4 support partial power-down operation?
Yes, SN74AUP1G17DBVRG4 fully supports partial power-down via its Ioff feature. When VCC = 0 V, all inputs and outputs enter a high-impedance state with leakage current limited to 0.6 µA max over temperature. This prevents back-current flow into the device from live signal lines - a critical capability in multi-rail systems where SN74AUP1G17DBVRG4 may remain connected while its supply rail is inactive.
What is the input hysteresis voltage (ΔVT) of SN74AUP1G17DBVRG4 at 3 V supply?
At VCC = 3 V, the input hysteresis voltage (ΔVT = VT+ – VT–) of SN74AUP1G17DBVRG4 is 0.79 V minimum and 1.31 V maximum over temperature. Specifically, VT+ = 1.88 V and VT– = 1.09 V typical at 25°C, providing robust noise immunity against transients up to ±395 mV. This hysteresis is intrinsic to the Schmitt-trigger design and does not require external components - a key advantage of SN74AUP1G17DBVRG4 in noisy environments.
Can SN74AUP1G17DBVRG4 operate with a 1.2 V supply?
Yes, SN74AUP1G17DBVRG4 is fully specified for operation at VCC = 1.2 V, with guaranteed performance including tpd ≤ 14.6 ns (CL = 5 pF), VT+ = 0.53 V, VT– = 0.26 V, and ICC ≤ 0.9 µA. Its 0.8 V to 3.6 V operating range makes SN74AUP1G17DBVRG4 compatible with modern ultra-low-voltage SoCs and energy-harvesting systems where supply rails fall below 1.8 V.
Is SN74AUP1G17DBVRG4 pin-compatible with other SOT-23-5 Schmitt-trigger buffers?
SN74AUP1G17DBVRG4 follows standard SOT-23-5 pinout (Pin 1: N.C., Pin 2: A, Pin 3: GND, Pin 4: Y, Pin 5: VCC), matching TI's SN74LVC1G17DBVR and ON Semiconductor's NC7SZ17P5X. However, functional compatibility requires verification of Ioff support, VCC range, and hysteresis thresholds - SN74AUP1G17DBVRG4 is not a drop-in replacement for parts lacking Ioff or operating below 1.65 V.
