Product details
Overview
SN74AUP1T57DBVT from Texas Instruments is a single-supply voltage-level translator IC with configurable logic gate functionality, supporting 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V bidirectional translation, Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection, and 4 mA output drive - deployed in battery-powered IoT sensor interfaces and mixed-voltage microcontroller GPIO expansion.
For engineers reviewing the SN74AUP1T57DBVT datasheet, SN74AUP1T57DBVT pinout, SN74AUP1T57DBVT application, or SN74AUP1T57DBVT equivalent, key selection criteria include its 6-pin SOT-23 package, 2.3–3.6 V supply range, nine programmable logic functions via input biasing, ultra-low static current (0.5 µA typical), and compatibility with slow or noisy input signals in space-constrained portable designs.
Technical Context
The SN74AUP1T57DBVT implements a single-input configurable logic cell using three user-defined inputs (A, B, C) tied to VCC or GND to select one of nine functions - including AND, NAND, OR, NOR, XNOR, inverter, and noninverting buffer - without external components. Its Schmitt-trigger inputs provide hysteresis (min ΔVT = 0.15 V at 3 V) for noise immunity on analog-digital boundary signals.
It features Ioff circuitry enabling safe operation during partial power-down (VCC = 0 V) with up to 3.6 V applied to I/O pins, and optimized 4 mA output drive minimizes signal reflections on short PCB traces. All logic states are defined across the full 2.3–3.6 V VCC range, with VIH/VIL thresholds scaling automatically per supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - accommodates battery voltage sag in portable systems without functional interruption |
| Logic Functions | Nine configurable gates (AND, OR, NAND, NOR, XNOR, inverter, buffer) - selected by hardwiring A/B/C to VCC/GND |
| Input Hysteresis | Min 0.15 V (at VCC = 3 V) - rejects noise on slow-rising/falling signals in mixed-signal environments |
| Ioff Current | Max 0.5 µA at VCC = 0 V - prevents back-powering and leakage in powered-down subsystems |
| Output Drive | ±4 mA at VCC = 3.3 V - sufficient for driving 50 Ω traces or multiple CMOS loads without overshoot |
| Propagation Delay | 1.6–4.4 ns (CL = 5–30 pF, VCC = 3.3 V, VI = 1.8 V) - enables timing-critical level-shifting up to ~100 MHz |
| Static Current | 0.5 µA typical - extends battery life in always-on sensor nodes and wearables |
Pinout & Package
SOT-23-6 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, gull-wing leads, pin 1 marked, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable logic input | Bias to VCC or GND to define logic function; accepts 0–3.6 V regardless of VCC state |
| 2 (B) | Configurable logic input | Second function-select input; Schmitt-triggered for noise rejection |
| 3 (GND) | Ground reference | Return path for all internal logic and output currents; must be low-impedance |
| 4 (C) | Configurable logic input | Third function-select input; determines inversion and gate topology per truth table |
| 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 output stage; enables Ioff when at 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Configurable logic gate | One device replaces nine discrete gates - reduces BOM count and board area in GPIO-limited MCUs |
| Schmitt-trigger inputs | 210 mV hysteresis (typical) - eliminates false triggering from EMI or crosstalk on long flex cables |
| Ioff protection | 0.5 µA max leakage at VCC = 0 V - allows hot-plug operation and safe isolation in multi-rail systems |
| Ultra-low power | 0.5 µA ICC (typical) - enables >10-year battery life in coin-cell-powered remote sensors |
| Voltage translation | Supports 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V - bridges legacy 1.8 V sensors to modern 3.3 V host processors |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T58DBVT | Dual-input XOR/XNOR configuration only; no AND/OR/NAND/NOR flexibility; identical VCC range and Ioff | Limited to differential signaling or parity generation; cannot emulate basic gates | Select when XOR/XNOR logic suffices and footprint compatibility is required |
| SN74LVC1T45DBVT | Direction-controlled dual-supply translator (no configurable logic); higher drive (±32 mA); no Schmitt inputs or Ioff | Requires direction pin and two supplies; unsuitable for noise-prone or partial-power-down use cases | Choose for high-speed bidirectional data buses where logic reconfiguration is unnecessary |

FAQ
What logic functions can the SN74AUP1T57DBVT implement?
The SN74AUP1T57DBVT supports nine distinct logic functions - including 2-input AND, OR, NAND, NOR, XNOR, inverter, and noninverting buffer - selected by connecting its A, B, and C inputs to VCC or GND per the Function Selection Table. Each configuration is deterministic and fully specified across temperature and voltage ranges; no firmware or external components are needed to change function.
Does the SN74AUP1T57DBVT require external pull-up or pull-down resistors?
No, the SN74AUP1T57DBVT does not require external pull-up or pull-down resistors for function selection. Its A, B, and C inputs are internally biased through Schmitt-trigger circuitry and are designed to be hard-wired directly to VCC or GND to configure logic behavior. Unused inputs must be terminated to VCC or GND per TI's SCBA004 guidance to prevent floating states and excessive current draw.
Can the SN74AUP1T57DBVT operate with VCC = 0 V?
Yes, the SN74AUP1T57DBVT supports Ioff protection: when VCC = 0 V, its I/O pins tolerate voltages from 0 V to 3.6 V with leakage current ≤0.5 µA. This enables safe hot-insertion, partial power-down modes, and isolation in multi-rail systems - a key requirement for battery-backed real-time clocks and always-on sensor hubs where subsystems power up/down independently.
What is the maximum capacitive load the SN74AUP1T57DBVT can drive reliably?
The SN74AUP1T57DBVT is characterized up to 30 pF load capacitance, with propagation delay increasing from 1.6 ns (5 pF) to 4.4 ns (30 pF) at VCC = 3.3 V and VI = 1.8 V. For reliable signal integrity, TI recommends limiting trace + load capacitance to ≤30 pF; exceeding this may cause timing violations or increased rise/fall times, especially at higher frequencies or lower VCC.
Is the SN74AUP1T57DBVT pin-compatible with other AUP single-gate devices?
Yes, the SN74AUP1T57DBVT shares the same SOT-23-6 (DBV) footprint and pinout as SN74AUP1T58DBVT, SN74AUP1T97DBVT, and SN74AUP1T98DBVT - enabling drop-in replacement within the AUP1T family for function upgrades or design reuse. However, logic behavior differs per part number, so firmware or biasing must be verified for functional equivalence.
