Product details
Overview
SN74AUP1T97DSFR from Texas Instruments is a single-supply voltage-level translator IC with configurable logic functionality, operating across 2.3 V to 3.6 V VCC, supporting 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V bidirectional level translation, featuring Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection (0.5 µA at VCC = 0 V), and 4 mA output drive - used in battery-powered IoT sensor interfaces and mixed-voltage microcontroller GPIO expansion.
For engineers reviewing the SN74AUP1T97DSFR datasheet, SN74AUP1T97DSFR pinout, SN74AUP1T97DSFR application, or SN74AUP1T97DSFR equivalent, key selection criteria include its 6-pin SON (1.0 mm × 1.0 mm) package, nine programmable gate functions via static input configuration, ultra-low ICC (0.9 µA max), hysteresis-enabled noise immunity, and compatibility with 1.8-V LVCMOS input thresholds.
Technical Context
The SN74AUP1T97DSFR implements a single-output, three-input configurable logic block with Schmitt-trigger inputs enabling robust switching in noisy analog-digital boundary environments. Its VCC-referenced threshold hysteresis (VT+ = 1.19 V / VT− = 0.5 V at 3.3 V) ensures reliable operation across wide input voltage ranges (0–3.6 V).
It supports partial-power-down via Ioff, allowing safe back-driving of inputs/outputs when VCC = 0 V, and delivers controlled 4 mA drive strength to minimize overshoot/undershoot on PCB traces - critical for signal integrity in high-density portable designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - accommodates battery voltage droop in portable systems without functional loss |
| Input Threshold Hysteresis (ΔVT) | 210 mV - rejects noise and stabilizes output during slow or noisy input transitions |
| Ioff Leakage | 0.5 µA max at VCC = 0 V - enables safe hot-insertion and system-level power sequencing |
| Output Drive Strength | ±4 mA - reduces line reflections and improves edge fidelity on short PCB traces |
| Propagation Delay (tpd) | 1.6 ns min (CL = 5 pF, VCC = 3.3 V, VI = 1.8 V) - supports >200 MHz data rates in level-shifted control paths |
| Power Dissipation Capacitance (Cpd) | 5 pF at 3.3 V - contributes to sub-1 µW static power at 10 MHz toggle rate |
| ESD Rating (HBM) | 2000 V - meets industrial I/O robustness requirements without external protection |
Pinout & Package
SN74AUP1T97DSFR uses a 6-pin SON (DSF) package measuring 1.0 mm × 1.0 mm with 0.5 mm pitch, optimized for space-constrained wearable and sensor modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable logic input | One of three static-select inputs determining gate function; tied to VCC/GND to set logic mode |
| 2 (B) | Configurable logic input | Second static-select input; combined with A and C to select among nine logic configurations |
| 3 (GND) | Ground reference | Return path for all internal circuitry; must be low-impedance for stable Schmitt-trigger thresholds |
| 4 (C) | Configurable logic input | Third static-select input; enables full function table including 2:1 MUX, AND, OR, NAND, NOR, inverter, buffer |
| 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 gate function; drives up to ±4 mA into capacitive loads |
Key Features
| Feature | Design Value |
|---|---|
| Nine configurable logic functions | Enables hardware-programmable gate behavior (e.g., 2:1 MUX, AND, OR, inverter) without firmware or external components |
| Schmitt-trigger inputs | 210 mV hysteresis eliminates chatter on slow-rising signals and improves noise margin in mixed-signal PCB layouts |
| Ioff partial-power-down support | Prevents current backflow and damage when VCC is off but I/Os remain active - essential for modular hot-swap subsystems |
| Ultra-low static power | 0.9 µA max ICC enables multi-year battery life in always-on sensor nodes and wearables |
| 1.8-V LVCMOS compatible inputs | Accepts standard 1.8-V logic levels while powered from 2.5 V or 3.3 V - simplifies voltage domain bridging in MCU peripherals |
Applications

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 |
|---|---|---|---|
| SN74AUP1T98DSFR | Same package and VCC range, but implements dual independent configurable gates (2× Y outputs) | Requires two simultaneous logic translations; occupies same board area but doubles functional density | Select when needing parallel level-shifting paths without increasing footprint |
| SN74LVC1T45DBVR | Fixed-direction dual-supply translator (no configurable logic); higher drive (32 mA), wider VCC range (1.65–5.5 V) | Used where direction control (DIR pin) and higher current are required, not logic reconfiguration | Select for high-drive unidirectional translation; avoid if Schmitt-trigger noise immunity or gate flexibility is needed |
Compared with SN74AUP1T98DSFR and SN74LVC1T45DBVR, the SN74AUP1T97DSFR uniquely combines single-gate configurability, sub-1-µA static power, and Schmitt-trigger noise rejection in a 1.0-mm² SON package - making it optimal for space- and energy-constrained mixed-voltage signal conditioning.

FAQ
What logic functions can the SN74AUP1T97DSFR implement?
The SN74AUP1T97DSFR supports nine distinct logic configurations-including 2:1 multiplexer, AND, OR, NAND, NOR, inverter, and non-inverting buffer-selected by hardwiring its A, B, and C inputs to VCC or GND per the Function Selection Table in the datasheet. Each configuration is static and fixed after power-up; no runtime reconfiguration is supported. The SN74AUP1T97DSFR achieves this using internal combinational logic gated by those inputs, eliminating need for external logic gates.
Does the SN74AUP1T97DSFR support bidirectional level translation?
No, the SN74AUP1T97DSFR is a unidirectional translator: inputs A/B/C accept 0–3.6 V signals (including 1.8-V LVCMOS), while output Y swings from 0 to VCC. It does not auto-detect direction or support true bidirectional data flow like bus switches. However, its wide input voltage range (0–3.6 V) and Ioff feature allow it to safely interface with multiple voltage domains when used in carefully designed one-way signal paths - for example, translating 1.8-V sensor alerts to a 3.3-V host interrupt line.
What is the thermal performance of the SN74AUP1T97DSFR in its DSF package?
The SN74AUP1T97DSFR in the 1.0 mm × 1.0 mm SON (DSF) package has a junction-to-ambient thermal resistance (RθJA) of 300°C/W, measured under standard JEDEC JESD51-7 conditions. This value assumes a 1-in² 2-oz copper pad with two thermal vias. In typical wearable PCB layouts with minimal copper, temperature rise remains below 5°C at full 4-mA output load due to the device's ultra-low power consumption (<1 µW dynamic at 10 MHz). No heatsink or thermal relief is required.
Can the SN74AUP1T97DSFR be used with floating or undefined input states?
No - all unused inputs (A, B, C) of the SN74AUP1T97DSFR must be explicitly tied to either VCC or GND to ensure predictable logic behavior and prevent increased ICC or oscillation. The datasheet mandates this in Section 5.3 Recommended Operating Conditions. Floating inputs cause excessive current draw and potential output instability due to the Schmitt-trigger structure's sensitivity to intermediate voltages. The SN74AUP1T97DSFR requires deterministic static configuration for reliable operation.
Is the SN74AUP1T97DSFR RoHS-compliant and lead-free?
Yes, the SN74AUP1T97DSFR is RoHS-compliant and features lead-free terminations with NIPDAU or NIPDAUAG finish, as confirmed in TI's Package Option Addendum. It meets JEDEC J-STD-020 moisture sensitivity Level-1 (unlimited floor life at ≤30°C/60% RH) and is rated for peak reflow temperatures up to 260°C. The device carries full IPC-7351 land pattern compliance and is qualified for industrial temperature range (–40°C to +85°C), making it suitable for automated SMT assembly in high-reliability production.
