Product details
Overview
SN74AUP1T98DSFR from Texas Instruments is a single-supply voltage-level translator with configurable logic functions, supporting 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V bidirectional translation, featuring Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection (0.5 μA at VCC = 0 V), 4 mA output drive, and operation across 2.3 V–3.6 V supply range. It enables flexible gate configuration (e.g., NAND, NOR, inverter, 2:1 MUX) in space-constrained battery-powered IoT sensor nodes.
For engineers reviewing the SN74AUP1T98DSFR datasheet, SN74AUP1T98DSFR pinout, SN74AUP1T98DSFR application, or SN74AUP1T98DSFR equivalent, key selection criteria include its ultra-low static current (0.5 μA), hysteresis-enhanced noise immunity, Ioff-enabled partial power-down capability, and compatibility with 0.4 mm max-height X2SON packaging for high-density PCB layouts.
Technical Context
The SN74AUP1T98DSFR implements a single-input configurable logic core using three user-defined control pins (A, B, C) tied to VCC or GND to select among nine standard logic functions-including inverter, noninverting buffer, 2-input NAND/NOR, and 2:1 data selector-without external components. Its AUP logic family delivers industry-leading low power consumption via optimized transistor sizing and rail-to-rail output swing.
Schmitt-trigger inputs provide 210 mV hysteresis (VT+ − VT−) to suppress noise on slow or noisy signal lines, while the Ioff feature ensures <0.5 μA leakage when VCC = 0 V, enabling safe back-driving of powered-down systems. The device operates across −40°C to +85°C with guaranteed timing performance up to 2.5 V/3.3 V supply combinations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - supports operation during battery voltage sag without functional loss |
| Input Hysteresis ΔVT | 210 mV - rejects noise on mixed-signal PCBs and tolerates slow input edges |
| Ioff Leakage | 0.5 μA at VCC = 0 V - prevents current backflow in partial-power-down modes |
| Output Drive | ±4 mA - reduces overshoot/undershoot on 50 Ω traces without external termination |
| Propagation Delay | 1.6 ns (min) to 9.8 ns (max) - varies with VCC, VI, CL; enables timing-critical level-shifting |
| Static ICC | 0.5 μA - extends battery life in always-on wearable and sensor applications |
| Package Height | 0.4 mm max - fits under mechanical shields and enables ultra-thin portable designs |
Pinout & Package
SN74AUP1T98DSFR uses the DSF package: 6-pin X2SON (0.8 mm × 0.8 mm, 0.4 mm max height), with wettable flanks and exposed thermal pad. Pin 1 is marked by a corner chamfer per JEDEC MO-287 X2AAF.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (B) | Configurable logic input | Second function-select input; determines logic truth table with A and C |
| 3 (C) | Configurable logic input / Select control | Third input; acts as enable/select line in MUX mode (e.g., Y = C?A:B) |
| 4 (GND) | Power ground | Reference return path for all signals and internal logic; must be low-impedance |
| 5 (Y) | Configurable logic output | Single-ended CMOS output; drives loads up to ±4 mA with rail-to-rail swing |
| 6 (VCC) | Supply voltage | Single power rail (2.3–3.6 V); powers internal logic and defines output voltage levels |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T97DSFR | Fixed inverter function only; no A/B/C configuration pins; identical DSF package and Ioff spec | Lacks logic configurability - suitable only where inversion is the sole required function | Select when design requires only inverting level shift with minimal footprint and lowest possible cost |

FAQ
What logic functions can the SN74AUP1T98DSFR implement?
The SN74AUP1T98DSFR supports nine configurable logic functions determined by tying its A, B, and C inputs to VCC or GND: inverter, noninverting buffer, 2-input NAND, 2-input NOR, 2-input NAND with one inverted input, 2-input NOR with one inverted input, and 2:1 data selector. Each configuration is validated in TI's FUNCTION SELECTION TABLE and requires no external components.
Does the SN74AUP1T98DSFR support bidirectional voltage translation?
No - the SN74AUP1T98DSFR is unidirectional: inputs A/B/C accept 1.8-V, 2.5-V, or 3.3-V logic levels, and output Y swings rail-to-rail at the VCC voltage (2.3–3.6 V). It does not auto-detect direction like bus transceivers; translation direction is fixed by supply and signal routing.
What is the maximum capacitive load the SN74AUP1T98DSFR can drive reliably?
The SN74AUP1T98DSFR is characterized up to 30 pF load capacitance across all VCC and input voltage conditions, with propagation delay specified from 1.6 ns (min) to 10.8 ns (max). For loads >30 pF, timing margins degrade and output rise/fall times increase; external buffering is recommended above this limit.
How does the Ioff feature of the SN74AUP1T98DSFR protect system integrity?
When VCC = 0 V, the SN74AUP1T98DSFR limits Ioff leakage to ≤0.5 μA even with inputs or outputs biased from 0 V to 3.6 V. This prevents current backflow into powered-down sections, avoids unintended wake-up of peripherals, and eliminates risk of latch-up in mixed-power-domain systems - critical for hot-swap and battery-save modes.
Is the SN74AUP1T98DSFR pin-compatible with other AUP1T-series devices in DSF packaging?
Yes - SN74AUP1T98DSFR shares identical X2SON-6 (DSF) pinout, footprint, and thermal pad layout with SN74AUP1T97DSFR and SN74AUP1T57DSFR. All use pin 1 (A), pin 2 (B), pin 3 (C), pin 4 (GND), pin 5 (Y), pin 6 (VCC), enabling drop-in replacement where logic function matches.
