Product details
Overview
SN74AUP1T97DRYR from Texas Instruments is a single-supply voltage-level translator IC with configurable logic functionality, supporting 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V bidirectional translation at VCC = 2.5 V or 3.3 V, featuring Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection (0.5 µA), and ultra-low static power (0.9 µA max). It enables compact signal interface in battery-powered IoT sensor nodes requiring level-shifting and basic logic.
For engineers reviewing the SN74AUP1T97DRYR datasheet, SN74AUP1T97DRYR pinout, SN74AUP1T97DRYR application, or SN74AUP1T97DRYR equivalent, this page delivers verified electrical specs, SON-6 package layout, nine logic configuration modes, noise-immune input thresholds, and real-world use cases for mixed-voltage microcontroller peripherals, low-power sensor hubs, and portable USB-C accessory interfaces.
Technical Context
The SN74AUP1T97DRYR implements a single-input configurable gate using three control pins (A, B, C) tied to VCC or GND to select among nine logic functions-including inverter, buffer, AND, OR, NAND, NOR, and 2:1 MUX-without external components. Its Schmitt-trigger inputs provide 210 mV hysteresis (VT+ = 1.19 V / VT− = 0.5 V at VCC = 3.3 V), rejecting noise on slow-rising signals common in analog-digital boundary circuits.
Operating across 2.3 V–3.6 V VCC, it supports partial power-down via Ioff (0.5 µA leakage when VCC = 0 V), allowing safe back-driving of inputs/outputs up to 3.6 V. Propagation delay ranges from 1.6 ns (CL = 5 pF, VI = 3.3 V, VCC = 3.3 V) to 9.8 ns (CL = 30 pF, VI = 1.8 V, VCC = 3.3 V), with output drive capability optimized at ±4 mA to suppress reflections.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
SN74AUP1T97DRYR uses a 6-pin SON (Small Outline No-Lead) package measuring 1.45 mm × 1.0 mm with wettable flank terminations, optimized for automated optical inspection and high-density PCB layouts. Pin 1 is located in Quadrant Q1 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable logic input | One of three logic-select inputs; tied to VCC/GND to define gate function per Function Selection Table |
| 2 (B) | Configurable logic input | Second logic-select input; determines truth table behavior alongside A and C pins |
| 3 (GND) | Ground reference | Primary return path for all internal circuitry; must be low-impedance for stable threshold operation |
| 4 (C) | Configurable logic input | Third logic-select input; enables full nine-function selection including 2:1 MUX and dual-inverted gates |
| 5 (VCC) | Supply voltage | Single power rail (2.3–3.6 V); powers internal logic and defines output voltage swing (0 to VCC) |
| 6 (Y) | Configurable logic output | Single-ended CMOS output reflecting selected function; drives loads up to ±4 mA with rail-to-rail swing |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation and configurable logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T98DRYR | Same AUP family, but implements fixed inverter + level-shift function only (no configurable logic) | Lacks nine-function selection; suited only for dedicated inverting translation paths | Choose when design requires only inverting level shift with identical low-power profile and SON-6 footprint |
| TXS0102DSGR | Two-channel auto-directional translator (no logic configuration); higher ICC (10 µA), larger X2SON-8 package (1.35 mm × 1.95 mm) | Supports bidirectional data buses (I²C, SMBus); not suitable for logic-gating tasks | Prefer for multi-bit bus translation where direction control is automatic; avoid when logic function flexibility or minimal size is required |

FAQ
What logic functions can SN74AUP1T97DRYR implement?
SN74AUP1T97DRYR supports nine configurable logic functions: inverter, noninverting buffer, 2-input AND, 2-input OR, 2-input NAND, 2-input NOR, 2-input AND with one inverted input, 2-input OR with one inverted input, and 2:1 data selector. Each is selected by hardwiring pins A, B, and C to VCC or GND per the Function Selection Table in the datasheet. SN74AUP1T97DRYR does not require external programming or configuration registers.
Does SN74AUP1T97DRYR support bidirectional voltage translation?
No, SN74AUP1T97DRYR is a unidirectional translator: inputs A/B/C accept 0–3.6 V signals (including 1.8 V LVCMOS), while output Y swings rail-to-rail between 0 V and VCC. It does not auto-detect direction like bus transceivers. However, its wide input range and Schmitt-trigger inputs allow reliable interfacing across 1.8 V, 2.5 V, and 3.3 V domains when VCC is set to the target output voltage. SN74AUP1T97DRYR is not suitable for true bidirectional buses such as I²C.
What is the maximum capacitive load SN74AUP1T97DRYR can drive reliably?
SN74AUP1T97DRYR is characterized up to 30 pF load capacitance, with propagation delay increasing from 1.6 ns (5 pF) to 9.8 ns (30 pF) depending on VCC and input voltage. Driving >30 pF may cause excessive rise/fall times or signal degradation. For loads exceeding 30 pF, add a series resistor (e.g., 22 Ω) near the driver to dampen ringing. SN74AUP1T97DRYR's ±4 mA drive strength is optimized for controlled impedance traces, not heavy capacitive loads.
Can SN74AUP1T97DRYR operate with VCC = 1.8 V?
No, SN74AUP1T97DRYR has a minimum recommended VCC of 2.3 V per the Absolute Maximum Ratings and Recommended Operating Conditions tables. Operation below 2.3 V risks incorrect logic behavior, increased propagation delay variation, and failure to meet output voltage specifications (VOH/VOL). For 1.8-V-only systems, consider TI's LVC or AVC families-but note those lack the AUP's ultra-low power and Schmitt-trigger inputs. SN74AUP1T97DRYR requires VCC ≥ 2.3 V to function correctly.
How does the Ioff feature protect SN74AUP1T97DRYR during power-down?
When VCC = 0 V, SN74AUP1T97DRYR's Ioff circuitry disables internal conduction paths, limiting input/output leakage to ≤0.5 µA even if signals from live 3.3-V subsystems are applied. This prevents back-powering of the powered-down domain and avoids latch-up or damage. The feature is critical in modular systems where boards may be hot-swapped or subsystems powered independently. SN74AUP1T97DRYR maintains this protection across –0.5 V to 3.6 V input/output voltage ranges during VCC = 0 V conditions.
