Product details
Overview
SN74AUP1T98DCKT from Texas Instruments is a single-supply voltage-level translator with configurable logic functions, operating from 2.3 V to 3.6 V VCC, supporting 1.8 V/2.5 V/3.3 V bidirectional translation, featuring Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection (0.5 μA), and 4 mA output drive - used in mixed-voltage I/O interfacing between microcontrollers and sensors in portable electronics.
For engineers reviewing the SN74AUP1T98DCKT datasheet, SN74AUP1T98DCKT pinout, SN74AUP1T98DCKT application, or SN74AUP1T98DCKT equivalent, key selection criteria include its 6-pin SC-70 package, configurable gate function via A/B/C input biasing, ultra-low static current (0.9 μA), hysteresis-enhanced noise immunity, and compatibility with battery-backed systems requiring partial-power-down operation.
Technical Context
The SN74AUP1T98DCKT implements a single-input configurable logic block using three user-defined control inputs (A, B, C) tied to VCC or GND to select among nine logic functions-including inverter, buffer, NAND, NOR, and 2:1 multiplexer-without external components. Its AUP logic family delivers industry-leading low power consumption across temperature (–40°C to 85°C) and supply range.
Schmitt-trigger inputs provide 210 mV hysteresis (VT+ − VT−) to reject noise on slow-rising signals, while Ioff circuitry ensures <0.5 μA leakage when VCC = 0 V, enabling safe back-driving of inputs/outputs during system power sequencing. Propagation delay ranges from 1.6 ns to 9.8 ns depending on VCC, VI, and CL (5–30 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 interruption |
| Input Threshold Hysteresis | 210 mV (ΔVT) - enables robust switching in noisy analog/mixed-signal environments |
| Ioff Leakage | 0.5 μA max at VCC = 0 V - prevents signal contention during partial power-down |
| Output Drive | ±4 mA - reduces overshoot/undershoot and improves signal integrity on PCB traces |
| Propagation Delay | 1.6 ns min (VCC = 3.3 V, VI = 1.8 V, CL = 5 pF) - supports high-speed level-shifting in real-time interfaces |
| Static Current (ICC) | 0.9 μA max - extends battery life in always-on sensor nodes and wearables |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial reliability requirements without external protection |
Pinout & Package
SN74AUP1T98DCKT uses the SC-70-6 (DCK) package: 2.0 mm × 1.25 mm, 0.65 mm pitch, 1.1 mm max height, with pin 1 marked by a dot or beveled edge. Pin 1 is top-left when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable logic input | User-biased (VCC/GND) to define logic function per truth table; accepts 0–3.6 V |
| 2 (B) | Configurable logic input | Second function-select input; Schmitt-triggered for noise rejection |
| 3 (C) | Configurable logic input | Third function-select input; determines gate type (e.g., NAND vs NOR) |
| 4 (GND) | Ground reference | Return path for all internal logic and I/O; 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 | Primary power rail (2.3–3.6 V); powers internal logic and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Nine configurable logic functions | Eliminates need for multiple discrete gates or FPGA logic by selecting function via static A/B/C biasing |
| Schmitt-trigger inputs | 210 mV hysteresis ensures clean transitions on slow or noisy signals (e.g., pushbutton, sensor outputs) |
| Ioff partial-power-down support | Enables hot-plug and power-gating scenarios where VCC may be off while I/O remains active |
| Ultra-low dynamic power | Cpd = 5 pF at 3.3 V enables sub-μW operation at 1 MHz clock rates in battery-critical designs |
| Pb-free SC-70 package | RoHS-compliant 2.0 mm × 1.25 mm footprint saves board space in compact IoT and wearable devices |

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 | Direction-controlled dual-supply translator (VCCA/VCCB); no configurable logic; higher ICC (10 μA) | Requires separate direction pin and two supplies; better for high-speed bidirectional buses (e.g., I²C) | Choose SN74LVC1T45DBVR when bidirectional data flow and tighter timing control are required over configurability. |
| SN74AUP1T57DCKR | Fixed 2-input XOR function; same AUP family, identical VCC/Ioff specs, but no function selection via A/B/C pins | Lacks nine-function flexibility; suited only for dedicated XOR applications (e.g., parity generation) | Choose SN74AUP1T57DCKR when XOR logic is static and board space allows fixed-function optimization. |
Compared with SN74LVC1T45DBVR and SN74AUP1T57DCKR, the SN74AUP1T98DCKT uniquely combines voltage translation, Schmitt-trigger noise immunity, and field-programmable logic in one SC-70 package - reducing component count where function agility and ultra-low power are prioritized over raw speed or fixed dual-supply operation.

FAQ
What logic functions can the SN74AUP1T98DCKT configure, and how are they selected?
The SN74AUP1T98DCKT supports nine logic functions - including inverter, noninverted buffer, 2-input NAND/NOR, and 2:1 data selector - selected by hardwiring inputs A, B, and C to VCC or GND per the Function Selection Table in the datasheet. No external programming or clock is needed; configuration is static and deterministic at power-up.
Does the SN74AUP1T98DCKT support bidirectional voltage translation?
No, the SN74AUP1T98DCKT is a unidirectional translator: inputs A/B/C accept 0–3.6 V logic levels, while output Y swings rail-to-rail between GND and VCC. For true bidirectional translation (e.g., I²C), TI recommends SN74LVC1T45 or similar dual-supply devices.
What is the maximum capacitive load the SN74AUP1T98DCKT can drive while maintaining specified propagation delay?
The SN74AUP1T98DCKT maintains guaranteed tpd ≤ 9.8 ns up to 30 pF load capacitance (CL) under worst-case conditions (VCC = 3.3 V, VI = 1.8 V). Beyond 30 pF, delay increases nonlinearly; for >50 pF loads, consider adding a buffer stage or reducing trace length.
How does the Ioff feature of the SN74AUP1T98DCKT protect system-level power sequencing?
When VCC = 0 V, the SN74AUP1T98DCKT limits Ioff leakage to ≤0.5 μA, allowing inputs and outputs to safely tolerate voltages from 0 V to 3.6 V. This prevents current backflow into powered-down sections - critical for hot-swap, battery backup, and multi-rail power sequencing in portable electronics.
Is the SN74AUP1T98DCKT compatible with 1.2-V input signals?
No - the SN74AUP1T98DCKT minimum valid VIH is 0.75 V (at VCC = 3 V) and 0.6 V (at VCC = 2.3 V), but its Schmitt-trigger thresholds are optimized for 1.8-V, 2.5-V, and 3.3-V logic families. 1.2-V signals fall below VIL(max) and will not register reliably; use SN74AUC1Gxx or level-shifter families rated for 1.2-V inputs instead.
