Product details
Overview
SN74AUP3G17RSER from Texas Instruments is a low-power triple Schmitt-trigger buffer IC in an 8-pin UQFN (RSE) package, operating from 0.8 V to 3.6 V supply. It delivers 5.1 ns maximum propagation delay at 3.3 V, 4.3 pF typical dynamic power dissipation, and 0.9 μA max static current-enabling robust signal conditioning in battery-powered portable interfaces.
For engineers reviewing the SN74AUP3G17RSER datasheet, SN74AUP3G17RSER pinout, SN74AUP3G17RSER application, or SN74AUP3G17RSER equivalent, key selection criteria include its Schmitt-trigger hysteresis (ΔVT = 0.79–1.31 V), Ioff partial-power-down support, 3.6-V I/O tolerance for mixed-voltage systems, and ultra-low input capacitance (1.5 pF).
Technical Context
The SN74AUP3G17RSER implements three independent non-inverting Schmitt-trigger buffers with asymmetric input thresholds: VT+ ranges from 0.3 V to 2.29 V and VT− from 0.1 V to 1.24 V across the 0.8–3.6 V VCC range. Its hysteresis (ΔVT) scales with supply voltage, ensuring noise immunity in noisy digital environments.
Designed for point-to-point signaling, it features Ioff circuitry that disables outputs during partial power-down, preventing backflow current when VCC = 0 V. Input clamp current is rated ±50 mA, and output drive capability reaches ±4 mA at 3 V, supporting direct interfacing with standard CMOS loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables operation across ultra-low-voltage microcontrollers and mixed-signal SoCs. |
| tpd Max | 5.1 ns at 3.3 V, CL = 15 pF - ensures timing-critical signal buffering without pipeline latency penalties. |
| ICC Max | 0.9 μA at TA = –40°C to 85°C - extends battery life in always-on sensor nodes and wearables. |
| Cpd Typ | 4.3 pF at 3.3 V - minimizes dynamic switching power in high-frequency clock/data paths. |
| ΔVT | 0.79–1.31 V (VCC = 3 V) - provides robust noise margin against EMI and ground bounce in compact PCB layouts. |
| Ioff | 0.6 μA max at VCC = 0 V - allows safe hot-insertion and multi-rail power sequencing without external isolation. |
| Ci Typ | 1.5 pF - reduces capacitive loading on preceding drivers, preserving signal edge rate integrity. |
Pinout & Package
SN74AUP3G17RSER uses an 8-pin UQFN (RSE) package with wettable flank leads, 1.55 mm × 1.55 mm body, 0.4 mm pitch, and exposed thermal pad. Pin 1 is located at top-left corner (quadrant Q2 per tape orientation), with solder mask-defined land pattern recommended.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary power supply input - must be decoupled locally with 0.1 μF ceramic capacitor to GND. |
| 2 | 1A | Input of Buffer 1 - Schmitt-trigger threshold enables clean signal restoration from slow or noisy sources. |
| 3 | 2A | Input of Buffer 2 - electrically isolated from other inputs; supports independent signal conditioning paths. |
| 4 | GND | Digital ground reference - connected to exposed thermal pad for thermal and EMI performance. |
| 5 | 1Y | Output of Buffer 1 - non-inverting, rail-to-rail swing, compatible with 3.6-V tolerant logic families. |
| 6 | 3A | Input of Buffer 3 - shares same electrical characteristics as 1A/2A; no internal crosstalk. |
| 7 | 2Y | Output of Buffer 2 - driven only when VCC is active; Ioff disables output if VCC = 0 V. |
| 8 | 3Y | Output of Buffer 3 - identical drive strength and timing to 1Y/2Y; supports parallel fanout. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | VT+ and VT− thresholds provide ≥0.79 V hysteresis at 3 V, eliminating contact bounce and EMI-induced glitches in pushbutton or encoder interfaces. |
| Ioff partial-power-down | Outputs enter high-impedance state when VCC = 0 V, enabling safe backplane hot-swap and multi-supply domain isolation without external MOSFETs. |
| 3.6-V I/O tolerance | Inputs accept up to 3.6 V regardless of VCC level (down to 0.8 V), simplifying level translation between 1.8-V logic and 3.3-V peripherals. |
| Ultra-low Ci (1.5 pF) | Minimizes capacitive loading on source drivers, preserving rise/fall times in high-speed data lines like I²C or SPI control signals. |
| NanoStar™-compatible footprint | RSE package matches TI's NanoStar™ layout guidelines, enabling drop-in replacement with YFP DSBGA variants in space-constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G17RSER | Higher ICC (max 10 μA), wider VCC range (1.65–5.5 V), no Ioff, lower hysteresis (ΔVT ≈ 0.3 V at 3.3 V) | Not suitable for partial-power-down or sub-1-V operation; better for 5-V legacy systems | Choose when interfacing with 5-V logic and power sequencing is not required. |
| SN74AUP2G17RSER | Dual-channel version, identical electrical specs, 6-pin UQFN package, no pin compatibility with SN74AUP3G17RSER | Reduces channel count but requires PCB redesign; saves ~0.5 mm² board area | Choose when only two buffered channels are needed and layout revision is acceptable. |

FAQ
What is the absolute maximum supply voltage rating for SN74AUP3G17RSER?
The absolute maximum VCC rating for SN74AUP3G17RSER is 4.6 V. Exceeding this voltage-even momentarily-may cause permanent damage. The device is fully specified for operation from 0.8 V to 3.6 V, and its 3.6-V I/O tolerance allows inputs to safely reach 3.6 V regardless of VCC level, making it ideal for mixed-voltage signal routing in modern portable designs.
Does SN74AUP3G17RSER support partial-power-down operation, and how does it behave when VCC = 0 V?
Yes, SN74AUP3G17RSER supports partial-power-down via its Ioff feature. When VCC = 0 V, the outputs enter a high-impedance state with leakage current ≤0.6 μA, preventing damaging current backflow from live inputs or outputs. This behavior is explicitly characterized in the datasheet and enables safe hot-plug operation in modular systems where subsystems power up/down independently.
What is the typical input hysteresis (ΔVT) of SN74AUP3G17RSER at 3.3 V supply, and why does it matter?
At VCC = 3.3 V, the typical input hysteresis ΔVT of SN74AUP3G17RSER is 1.05 V (VT+ = 2.29 V, VT− = 1.24 V). This wide hysteresis suppresses noise-induced false triggering on slow-rising signals such as those from mechanical switches, thermistors, or long PCB traces-eliminating the need for external RC filtering and improving system reliability in electrically noisy environments.
Can SN74AUP3G17RSER be used as a level translator between 1.8-V and 3.3-V logic domains?
Yes, SN74AUP3G17RSER functions as a unidirectional level translator: its inputs tolerate up to 3.6 V regardless of VCC, and its outputs swing rail-to-rail between GND and VCC. When powered at 1.8 V, it accepts 3.3-V inputs and outputs clean 1.8-V logic levels-ideal for interfacing 3.3-V sensors with 1.8-V MCUs without external translators or resistive dividers.
What is the recommended PCB land pattern for the RSE package of SN74AUP3G17RSER?
The RSE package of SN74AUP3G17RSER requires a solder-mask-defined land pattern with 0.35 mm × 0.35 mm pads (6×), 0.25 mm × 0.25 mm pads (4×), and a 1.35 mm × 1.3 mm exposed thermal pad. TI recommends non-solder-mask-defined (NSMD) copper for the thermal pad to ensure optimal thermal transfer and solder joint reliability during reflow.
