Product details
Overview
SN74AUP1T98DRYR from Texas Instruments is a single-supply voltage-level translator with nine configurable logic functions, operating from 2.3 V to 3.6 V VCC and supporting 1.8 V/2.5 V/3.3 V bidirectional level translation. It features Schmitt-trigger inputs (ΔVT = 250 mV typ), Ioff protection (0.5 μA max), 4 mA output drive, and 6-pin SON (DRY) package. It enables flexible gate logic in space-constrained battery-powered IoT sensor nodes.
For engineers reviewing the SN74AUP1T98DRYR datasheet, SN74AUP1T98DRYR pinout, SN74AUP1T98DRYR application, or SN74AUP1T98DRYR equivalent, key selection criteria include its configurable logic capability, ultra-low static current (0.9 μA max), hysteresis-enhanced noise immunity, and compatibility with 1.8-V LVCMOS inputs while powered from 2.5-V or 3.3-V rails.
Technical Context
The SN74AUP1T98DRYR implements a single-input-selectable logic block using three configuration pins (A, B, C) tied to VCC or GND to select among nine functions-including 2-to-1 multiplexer, NAND, NOR, inverter, and buffer-without external logic. Its AUP low-power process delivers <0.9 μA ICC at 25°C and supports partial power-down via Ioff when VCC = 0 V.
Schmitt-trigger inputs provide 210–560 mV hysteresis (ΔVT) across VCC range, enabling robust operation with slow-rising signals and noise rejection in mixed-signal environments. Output switching is optimized for signal integrity: 4 mA drive strength minimizes overshoot/undershoot, and propagation delay ranges from 1.6 ns (VCC = 3.3 V, CL = 5 pF) to 10.8 ns (VCC = 2.5 V, CL = 30 pF).
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) | 250 mV typ - rejects noise on analog-digital interface lines and stabilizes outputs during slow transitions |
| Ioff Leakage | 0.5 μA max at VCC = 0 V - prevents backfeeding and enables safe hot-insertion in multi-rail systems |
| Output Drive Strength | ±4 mA - reduces transmission-line reflections and improves rise/fall time control on PCB traces |
| Propagation Delay (tpd) | 1.6 ns min (3.3 V, 5 pF) - supports high-speed logic interfacing up to ~300 MHz toggle rate |
| Static Current (ICC) | 0.9 μA max - extends battery life in always-on sensor edge devices by >10× vs. standard LVC |
| Input Capacitance (Ci) | 1.5 pF at 3.3 V - minimizes loading on driving source, critical for high-impedance GPIOs |
Pinout & Package
SN74AUP1T98DRYR uses a 6-pin 1.2 mm × 1.6 mm SON (DRY) package with wettable flank leads, 0.4 mm pitch, and exposed thermal pad. Pin 1 is marked by index area in top-left corner (Q1 quadrant per tape orientation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable Input A | Primary logic input; tied to VCC/GND to define function per selection table |
| 2 (B) | Configurable Input B | Secondary logic input; combined with A and C to determine gate behavior |
| 3 (C) | Configurable Input C | Select line for 2:1 MUX mode; also configures inversion and gate type |
| 4 (GND) | Ground Reference | Return path for all internal logic and I/O; must be low-impedance for noise immunity |
| 5 (Y) | Configurable Output | Single logic output; drives up to 4 mA with rail-to-rail swing (VOL ≤ 0.45 V, VOH ≥ 2.55 V @ 3 V) |
| 6 (VCC) | Supply Voltage | Single power rail; powers internal logic and defines output voltage levels and input thresholds |
Key Features
| Feature | Design Value |
|---|---|
| Nine Configurable Logic Functions | Eliminates need for multiple discrete gates or CPLD logic; reduces BOM count and board area in compact designs |
| Schmitt-Trigger Inputs | Enables reliable operation with noisy or slow-switching signals (e.g., mechanical switches, ADC reference lines) |
| Ioff Partial-Power-Down Support | Allows isolation of powered-down subsystems without damaging signal integrity on shared buses |
| Ultra-Low Static Power | 0.9 μA max ICC enables multi-year battery life in coin-cell-powered wearables and remote sensors |
| Wide VCC Compatibility | 2.3–3.6 V operation supports Li-ion, Li-po, and 2xAA alkaline battery discharge profiles without regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1T45DBVR | Non-configurable dual-supply translator; requires separate VCCA/VCCB rails; no Schmitt inputs or Ioff | Best for fixed-direction, dual-rail systems where configurability and ultra-low Icc are not required | Choose SN74LVC1T45DBVR only if dual-supply architecture is already established and hysteresis is unnecessary |
| SN74AUP1T57DBVR | Fixed-function inverter/buffer only; lacks 9-function configurability and C-input select capability | Suitable for simple signal inversion or buffering but cannot replace multiplexer or NAND/NOR logic functions | Use SN74AUP1T57DBVR only when logic function is strictly limited to inverting/non-inverting buffer |

FAQ
What logic functions can SN74AUP1T98DRYR implement?
SN74AUP1T98DRYR implements nine logic functions via configuration of pins A, B, and C: 2-to-1 data selector, 2-input NAND, 2-input NOR, inverter, noninverted buffer, and variants with one inverted input. The Function Selection Table in the SCES614I datasheet maps each combination. No external components are needed - all configuration is done by tying inputs to VCC or GND.
Does SN74AUP1T98DRYR support bidirectional level translation?
No, SN74AUP1T98DRYR is a unidirectional translator: inputs accept 1.8-V/2.5-V/3.3-V logic levels depending on VCC, and output Y swings rail-to-rail relative to VCC. It does not auto-detect direction or support true bidirectional bus translation like the TXB series. Signal flow is strictly A/B/C → Y.
What is the maximum recommended load capacitance for SN74AUP1T98DRYR?
SN74AUP1T98DRYR is characterized up to 30 pF load capacitance in switching specifications. At CL = 30 pF and VCC = 3.3 V, tpd is 4.4 ns max. Driving loads >30 pF may increase propagation delay nonlinearly and degrade edge rates; for >50 pF, consider buffering or layout optimization to minimize trace capacitance.
Can SN74AUP1T98DRYR operate with VCC = 1.8 V?
No, SN74AUP1T98DRYR has a minimum VCC of 2.3 V per Recommended Operating Conditions. While inputs accept 1.8-V signals (e.g., from a 1.8-V MCU), the device itself must be powered from ≥2.3 V to ensure proper internal biasing, output drive, and Schmitt-trigger hysteresis performance.
Is the exposed thermal pad on SN74AUP1T98DRYR electrically connected?
Yes, the exposed thermal pad on the SN74AUP1T98DRYR SON package is internally connected to GND. TI's DRY0006A package drawing specifies soldering the pad to a GND plane for optimal thermal performance and EMI reduction. Leaving it floating degrades thermal resistance by >30% and may impact long-term reliability under sustained load.
