Product details
Overview
SN74AUP1T57DBVR from Texas Instruments is a single-supply voltage-level translator IC with configurable logic functions, operating from 2.3 V to 3.6 V supply, supporting 1.8 V ↔ 2.5 V ↔ 3.3 V bidirectional translation, featuring Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection (0.5 µA at VCC = 0 V), and 4 mA output drive - used in mixed-voltage microcontroller I/O interfacing and battery-powered sensor nodes.
For engineers reviewing the SN74AUP1T57DBVR datasheet, SN74AUP1T57DBVR pinout, SN74AUP1T57DBVR application, or SN74AUP1T57DBVR equivalent, key selection criteria include its 6-pin SOT-23 package, nine programmable gate configurations (e.g., AND, NAND, XNOR, buffer), ultra-low static current (0.5 µA), hysteresis-enhanced noise immunity, and compatibility with partial-power-down systems.
Technical Context
The SN74AUP1T57DBVR implements a single-input configurable logic cell using three user-defined control pins (A, B, C) tied to VCC or GND to select one of nine standard logic functions - including inverter, noninverting buffer, 2-input AND/NAND/OR/NOR/XNOR - without external components. Its AUP logic family delivers industry-leading low power consumption across temperature (–40°C to 85°C).
Schmitt-trigger inputs provide 210 mV hysteresis (VT+ = 1.19 V / VT– = 0.5 V at VCC = 3.3 V), enabling robust operation with slow-rising or noisy signals. The Ioff feature isolates inputs/outputs during power-off (VCC = 0 V), allowing safe back-driving up to 3.6 V while limiting leakage to ≤0.5 µA.
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 loss |
| Logic Translation | 1.8 V ↔ 2.5 V ↔ 3.3 V - enables interoperability between legacy and modern low-voltage logic domains |
| Input Hysteresis ΔVT | 210 mV (typ.) - rejects noise on analog-mixed-signal PCBs and ensures clean output transitions |
| Ioff Leakage | ≤0.5 µA at VCC = 0 V - prevents current backflow in partial-power-down modes for energy-sensitive designs |
| Output Drive | ±4 mA at VCC = 3.3 V - minimizes signal reflections and overshoot on short PCB traces |
| Propagation Delay | 1.6 ns (min) to 4.4 ns (max) at CL = 30 pF - supports >100 MHz toggle rates in low-capacitance interfaces |
| Static Current ICC | 0.5 µA (typ.) - extends battery life in always-on IoT edge nodes and wearables |

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic translator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T58DBVR | Fixed 2-input XOR function only; no A/B/C configuration pins; identical VCC range and Ioff spec | Lacks programmability - suitable only where XOR is required, not general-purpose logic translation | Select when deterministic XOR behavior is needed and board space allows dedicated function vs. reconfigurable flexibility |
| SN74LVC1T45DBVR | Bidirectional auto-direction sensing; no Schmitt triggers; higher ICC (10 µA); supports 1.65–5.5 V VCC | Requires direction-control signal or bus arbitration; less noise-immune on slow edges; wider voltage range | Prefer for bidirectional data buses (e.g., I²C pull-up domain bridging); avoid where Schmitt noise rejection is critical |
Compared with SN74AUP1T58DBVR and SN74LVC1T45DBVR, the SN74AUP1T57DBVR uniquely combines field-programmable logic function selection, Schmitt-trigger noise immunity, and sub-µA quiescent current - making it optimal for space-constrained, battery-operated, mixed-signal edge nodes requiring flexible I/O adaptation.

FAQ
What logic functions can the SN74AUP1T57DBVR implement?
The SN74AUP1T57DBVR supports nine configurable logic functions determined by connecting its A, B, and C inputs to VCC or GND: 2-input AND, NOR (both inputs inverted), NAND (one input inverted), OR (one input inverted), AND (both inputs inverted), NOR, XNOR, inverter, and noninverted buffer. Each configuration is validated in TI's Function Selection Table and requires no external components - the SN74AUP1T57DBVR delivers full flexibility from a single 6-pin SOT-23 package.
Does the SN74AUP1T57DBVR support bidirectional voltage translation?
No, the SN74AUP1T57DBVR is a unidirectional translator: inputs A, B, C accept 0–3.6 V logic levels (including 1.8 V and 2.5 V), while output Y is referenced to VCC and swings between 0 V and VCC. It does not auto-sense direction like bus transceivers. For true bidirectional translation, TI recommends SN74LVC1T45DBVR - but the SN74AUP1T57DBVR excels where signal flow is fixed and ultra-low power is mandatory.
What is the maximum capacitive load the SN74AUP1T57DBVR can drive reliably?
The SN74AUP1T57DBVR is characterized up to 30 pF load capacitance, with propagation delay ranging from 1.6 ns (min) to 4.4 ns (max) at VCC = 3.3 V and CL = 30 pF. Its 4 mA output drive capability ensures clean edges into typical PCB trace + input capacitance loads. Driving >30 pF may increase delay and degrade edge monotonicity - for heavier loads, add a local buffer or reduce trace length. The SN74AUP1T57DBVR's Co = 3 pF (typ.) minimizes loading on upstream drivers.
How does the Ioff feature of the SN74AUP1T57DBVR protect system-level power sequencing?
The Ioff feature disables internal circuitry when VCC = 0 V, limiting input/output leakage to ≤0.5 µA even when signals from powered sections (up to 3.6 V) are applied. This prevents back-powering of dormant subsystems and avoids latch-up in multi-rail systems. In practice, the SN74AUP1T57DBVR allows safe hot-plug operation and independent power cycling - critical for modular designs where the SN74AUP1T57DBVR bridges domains with staggered power-up sequences.
Is the SN74AUP1T57DBVR pin-compatible with other members of the SN74AUP1Txx family?
No - the SN74AUP1T57DBVR has a unique 6-pin SOT-23 pinout (A-B-GND-C-VCC-Y) optimized for its three control inputs and single output. Other variants like SN74AUP1T58DBVR (XOR-only) share the same DBV package but differ in pin function mapping; SN74AUP1T97DBVR (dual supply translator) uses different pin assignments. Always verify pinout against SCES611G datasheet Figure 1 - the SN74AUP1T57DBVR's functionality depends entirely on correct A/B/C configuration per its logic table.
