Product details
Overview
SN74AUP1T98DCKR 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 at VCC = 2.5 V or 3.3 V, featuring Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection (0.5 μA), and 4 mA output drive - used in mixed-voltage I/O bridging between microcontrollers and legacy peripherals.
For engineers reviewing the SN74AUP1T98DCKR datasheet, SN74AUP1T98DCKR pinout, SN74AUP1T98DCKR application, or SN74AUP1T98DCKR equivalent, key selection criteria include its 6-pin SC-70 package, 2.3–3.6 V supply range, hysteresis-enabled noise immunity, nine programmable logic configurations, and partial-power-down capability for battery-backed systems.
Technical Context
The SN74AUP1T98DCKR 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, NAND, NOR, and 2:1 multiplexer-without external components. Its AUP ultra-low-power process enables static current as low as 0.5 μA and dynamic power dissipation of 4–5 pF at 10 MHz.
Schmitt-trigger inputs provide 210 mV hysteresis (VT+ − VT−) across 2.3–3.6 V VCC, rejecting slow-rising or noisy signals in mixed-signal environments. Ioff functionality ensures <0.5 μA leakage when VCC = 0 V, allowing safe back-driving of inputs/outputs up to 3.6 V during system power-down sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - accommodates battery voltage droop while maintaining full logic operation |
| Input Hysteresis ΔVT | 210 mV - rejects noise on slow or noisy input transitions in mixed-mode PCBs |
| Ioff Leakage | 0.5 μA at VCC = 0 V - enables safe partial-power-down without signal contention |
| Output Drive | ±4 mA - reduces overshoot/undershoot on 50 Ω traces without external termination |
| Propagation Delay | 1.6–4.4 ns (CL = 5–30 pF, VI = 1.8–3.3 V) - supports >100 MHz data rates in level-shifted interfaces |
| Logic Configurations | Nine functions via A/B/C pin strapping - eliminates need for discrete gates or FPGA logic resources |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial I/O robustness requirements without added protection |
Pinout & Package
SN74AUP1T98DCKR 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 index area in top-left corner per JEDEC MO-203AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable Input | Strapped to VCC/GND to define logic function; accepts 0–3.6 V regardless of VCC |
| 2 (B) | Configurable Input | Second logic configuration input; Schmitt-triggered for noise immunity |
| 3 (GND) | Ground Reference | Return path for all internal circuitry; must be low-impedance for stable threshold behavior |
| 4 (C) | Configurable Input | Third logic configuration input; determines gate type (e.g., NAND vs. NOR) |
| 5 (Y) | Configurable Output | Single logic output with 4 mA drive; rail-to-rail swing (VOL ≤ 0.45 V, VOH ≥ VCC − 0.4 V) |
| 6 (VCC) | Supply Input | Single power rail (2.3–3.6 V); powers internal logic and defines output voltage levels |
Key Features

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 (A/B sides); no Schmitt inputs; higher ICC (10 μA) | Requires direction pin and two supplies; unsuitable for noise-prone analog sensor inputs | Choose when bidirectional data flow (e.g., I²C) demands separate A/B rails and direction control |

FAQ
What logic functions can SN74AUP1T98DCKR implement?
The SN74AUP1T98DCKR supports nine configurable logic functions - including inverter, noninverted buffer, 2-input NAND/NOR gates (with or without inverted inputs), and 2:1 data selector - selected by connecting its A, B, and C inputs to VCC or GND per the Function Selection Table in the datasheet. Each configuration is implemented internally without external components, and the SN74AUP1T98DCKR retains full voltage translation capability across all modes.
Does SN74AUP1T98DCKR require external pull-up or pull-down resistors?
No, the SN74AUP1T98DCKR does not require external pull-up or pull-down resistors for normal operation. Its inputs are Schmitt-triggered and internally biased; unused inputs must be tied to VCC or GND per TI's SCBA004 guidance to prevent floating states, but no passive components are needed for signal conditioning or logic configuration. The SN74AUP1T98DCKR achieves stable operation with direct strapping only.
Can SN74AUP1T98DCKR operate with VCC = 2.3 V while translating 1.8-V inputs?
Yes, SN74AUP1T98DCKR is fully specified to operate at VCC = 2.3 V while accepting 1.8-V LVCMOS inputs. Its input thresholds (VT+ = 0.6–0.75 V, VT− = 0.35–0.5 V at VCC = 2.3 V) ensure reliable recognition of 1.8-V logic levels, and its output swing (VOH ≥ 2.2 V, VOL ≤ 0.33 V) meets 2.5-V system requirements. This capability is explicitly validated in the Recommended Operating Conditions table for SN74AUP1T98DCKR.
Is SN74AUP1T98DCKR compatible with 3.3-V-only systems?
Yes, SN74AUP1T98DCKR supports 3.3-V-only operation: it accepts 3.3-V inputs when VCC = 3.3 V, delivers rail-to-rail outputs (VOH ≥ 2.9 V, VOL ≤ 0.45 V), and maintains propagation delay ≤ 4.4 ns (CL = 30 pF). Its absolute maximum rating allows VI up to 4.6 V, and its Schmitt-trigger inputs ensure clean switching even with slow 3.3-V edges - making SN74AUP1T98DCKR suitable for upgrading legacy 3.3-V logic without redesign.
What is the thermal performance of SN74AUP1T98DCKR in SC-70 package?
The SN74AUP1T98DCKR in SC-70 (DCK) package has a junction-to-ambient thermal resistance (θJA) of 259°C/W, measured per JESD 51-7. At 4 mA output current and 3.3 V VCC, typical power dissipation is <150 μW - resulting in negligible temperature rise (<0.04°C) under normal operation. No heatsinking or airflow is required, and the SN74AUP1T98DCKR remains within its –40°C to 85°C operating range even in sealed enclosures.
