Product details
Overview
SN74AUP1T97DSF2 from Texas Instruments is a single-supply voltage-level translator IC with configurable logic functionality, supporting 1.8 V ↔ 2.5 V, 1.8 V ↔ 3.3 V, and 2.5 V ↔ 3.3 V bidirectional translation at VCC = 2.5 V or 3.3 V. It features Schmitt-trigger inputs (ΔVT = 210 mV), Ioff support for partial power-down (0.5 µA leakage), 4 mA output drive, and operates across 2.3 V–3.6 V supply range. It is used in mixed-voltage I/O interfacing between microcontrollers and peripherals in portable battery-powered systems.
For engineers reviewing the SN74AUP1T97DSF2 datasheet, SN74AUP1T97DSF2 pinout, SN74AUP1T97DSF2 application, or SN74AUP1T97DSF2 equivalent, key selection criteria include its 6-pin SON (DSF) package, configurable gate logic via A/B/C input biasing, low-noise Schmitt-trigger thresholds, ultra-low static/dynamic power (0.5 µA ICC, 4–5 pF Cpd), and Ioff-enabled safe operation during VCC = 0 V conditions.
Technical Context
The SN74AUP1T97DSF2 implements a single-output, three-input configurable logic block with Schmitt-trigger inputs enabling robust noise rejection on slow or noisy signal lines. Its internal architecture supports nine discrete logic functions-including inverter, buffer, AND, OR, NAND, NOR, and 2:1 MUX-selected by hardwiring A, B, and C to VCC or GND per the Function Selection Table.
It uses TI's AUP (Advanced Ultra-Low-Power) logic process optimized for sub-1 µA quiescent current and minimal dynamic power consumption. The device achieves propagation delays as low as 1.6 ns (typical, CL = 5 pF, VCC = 3.3 V, VI = 1.8 V) while maintaining rail-to-rail output swing and latch-up immunity exceeding 100 mA per JESD78 Class II.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - accommodates battery voltage droop without functional loss in portable systems |
| Input Threshold Hysteresis (ΔVT) | 210 mV - ensures clean switching and noise immunity on analog-mixed-signal PCBs |
| Ioff Leakage (VCC = 0 V) | 0.5 µA max - enables safe back-driving of inputs/outputs during system sleep or hot-swap |
| Output Drive Strength | ±4 mA - reduces overshoot/undershoot and line reflections on short PCB traces |
| Propagation Delay (tpd) | 1.6–4.4 ns (CL = 5–30 pF, VCC = 2.5/3.3 V) - supports >100 MHz data rates in level-shifted control paths |
| Power Dissipation Capacitance (Cpd) | 4 pF (VCC = 2.5 V), 5 pF (VCC = 3.3 V) - quantifies dynamic power draw at 10 MHz clock frequency |
| ESD Rating (HBM) | 2000 V - meets industrial-grade ESD robustness per ANSI/ESDA/JEDEC JS-001 |
Pinout & Package
The SN74AUP1T97DSF2 is housed in a 1.0 mm × 1.0 mm, 6-pin SON (DSF) package with wettable flank terminations, optimized for automated optical inspection (AOI) and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable logic input | Bias to VCC/GND to select logic function per Function Selection Table; Schmitt-triggered |
| 2 (B) | Configurable logic input | Second logic configuration input; same Schmitt-trigger characteristics as Pin 1 |
| 3 (GND) | Ground reference | Primary return path for VCC and all I/O; must be low-impedance for noise integrity |
| 4 (C) | Configurable logic input | Third logic configuration input; determines gate type (e.g., MUX select, enable, inversion control) |
| 5 (VCC) | Supply voltage | Single power rail (2.3–3.6 V); powers internal logic and defines output voltage levels |
| 6 (Y) | Configurable logic output | Active-drive output (±4 mA); rail-to-rail swing; supports 1.8/2.5/3.3-V logic families |
Key Features
| Feature | Design Value |
|---|---|
| Nine configurable logic functions | Enables one device to replace multiple fixed-function gates (e.g., 74AUP1G04, 74AUP1G08, 74AUP1G14), reducing BOM count and board space |
| Schmitt-trigger inputs | 210 mV hysteresis rejects up to ±100 mV of input noise and tolerates slow edge rates common in sensor or switch interfaces |
| Ioff partial-power-down | Allows safe connection to live buses when VCC = 0 V - critical for hot-plug, battery-backup, and multi-rail power sequencing |
| Ultra-low power consumption | 0.5 µA typical ICC and 4–5 pF Cpd enable >10-year battery life in always-on IoT nodes and wearables |
| SON (DSF) 1.0 mm × 1.0 mm package | Minimizes PCB footprint and thermal resistance (RθJA = 300°C/W), ideal for space-constrained portable designs |
Applications
| Industrial Sensor Interface | Wearable Health Monitor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T98DSF2 | Same AUP family, but implements fixed inverter function only - no configurable logic inputs | Lacks A/B/C configuration pins; suitable only for simple inversion, not MUX or gate logic | Select when only inverting level translation is needed and board space permits identical DSF footprint |
| TXS0102DSGR | Two-channel auto-directional translator; no Schmitt inputs; higher ICC (10 µA); larger 8-pin VSSOP package | Supports bidirectional data (e.g., I²C), but cannot implement logic functions or tolerate floating inputs | Choose for I²C/SMBus translation where direction control is automatic and noise immunity is secondary |
Compared with SN74AUP1T98DSF2 and TXS0102DSGR, the SN74AUP1T97DSF2 uniquely combines configurable logic, Schmitt-trigger noise rejection, and ultra-low power in a 1.0 mm × 1.0 mm package - making it optimal for space- and power-constrained unidirectional control signal translation with functional flexibility.

FAQ
What logic functions can the SN74AUP1T97DSF2 perform?
The SN74AUP1T97DSF2 supports nine configurable logic functions: inverter, noninverted buffer, 2-input AND, OR, NAND, NOR, AND/NOR with one inverted input, OR/NAND with one inverted input, and 2:1 data selector. These are selected by connecting inputs A, B, and C to VCC or GND per TI's Function Selection Table - no external programming is required. Each configuration is implemented in hardware and retains full Schmitt-trigger and Ioff functionality.
Does the SN74AUP1T97DSF2 require external pull-up resistors?
No, the SN74AUP1T97DSF2 does not require external pull-up resistors for normal operation. Its inputs are Schmitt-triggered and internally biased; all unused inputs must be tied to VCC or GND per TI's SCBA004 guideline to prevent floating states. Output Y is actively driven and does not rely on external termination for logic-level definition.
Can the SN74AUP1T97DSF2 translate between 1.8 V and 5 V logic levels?
No, the SN74AUP1T97DSF2 cannot translate to 5 V. Its absolute maximum ratings limit VO and VI to 4.6 V, and its recommended operating conditions specify VCC from 2.3 V to 3.6 V. Translation is supported only among 1.8 V, 2.5 V, and 3.3 V domains - e.g., 1.8 V ↔ 2.5 V, 1.8 V ↔ 3.3 V, or 2.5 V ↔ 3.3 V - with VCC set to either 2.5 V or 3.3 V accordingly.
What is the significance of the "DSF2" suffix in SN74AUP1T97DSF2?
The "DSF2" suffix denotes the specific package variant: DSF indicates the 1.0 mm × 1.0 mm SON (Small Outline No-lead) package with wettable flanks, and "2" refers to TI's internal revision or tape-and-reel configuration code (e.g., reel size, orientation, or lead finish). This matches TI's official orderable part SN74AUP1T97DSFR, confirming compatibility with standard DSF footprint and assembly processes.
How does Ioff protection work in the SN74AUP1T97DSF2 during power-down?
When VCC = 0 V, the SN74AUP1T97DSF2's Ioff circuitry disables internal conduction paths, limiting input/output leakage to ≤0.5 µA even if signals from 0 V to 3.6 V are applied. This prevents back-powering of the VCC rail or damage to upstream drivers - a critical feature for hot-swap interfaces, battery-backed subsystems, and multi-rail power sequencing where partial power-down is routine.
