Product details
Overview
SN74AUP1T57YZPR 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, 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 IoT edge nodes.
For engineers reviewing the SN74AUP1T57YZPR datasheet, SN74AUP1T57YZPR pinout, SN74AUP1T57YZPR application, or SN74AUP1T57YZPR equivalent, key selection criteria include its NanoStar WCSP YZP package (0.8 mm × 0.8 mm, 0.23-mm large bump), 2.3–3.6 V supply range, nine programmable logic configurations, low dynamic power (Cpd = 4 pF at 2.5 V), and Ioff support for partial-power-down systems.
Technical Context
The SN74AUP1T57YZPR implements a single-input configurable logic block using three user-defined control pins (A, B, C) tied to VCC or GND to select among nine functions-including AND, NAND, NOR, OR, XNOR, inverter, and noninverting buffer-without external components. Its Schmitt-trigger inputs provide noise immunity with VT+ = 1.19 V / VT− = 0.5 V (at VCC = 3.3 V), enabling robust operation on slow-rising or noisy signals.
It operates across 2.3–3.6 V, supports voltage translation between 1.8-V, 2.5-V, and 3.3-V domains, and features Ioff protection allowing safe back-driving when VCC = 0 V. Propagation delay ranges from 1.6 ns (CL = 5 pF, VI = 1.8 V, VCC = 3.3 V) to 4.4 ns (CL = 30 pF, same conditions), with output drive optimized to minimize overshoot/undershoot.
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 functionality |
| Input Threshold Hysteresis | ΔVT = 210 mV - rejects noise on mixed-signal PCBs and enables clean switching on slow edges |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation with logic configuration applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T58DBVR | Dual-input XOR/XNOR only; fixed function (no A/B/C configuration); SOT-23-6 package | Lacks nine-function flexibility; suited for dedicated XOR-based level shifters (e.g., clock phase alignment) | Select when only XOR/XNOR logic is needed and board space allows SOT-23 footprint |
| SN74LVC1T45DBVR | Direction-controlled bidirectional translator; no logic configuration; 3-state enable; higher drive (±24 mA) | Requires direction pin and external control logic; better for data bus translation than GPIO logic conditioning | Choose for bidirectional data lanes (e.g., I²C pull-up translation) where direction management is acceptable |
Compared with SN74AUP1T57YZPR, SN74AUP1T58DBVR offers simpler XOR-specific translation but lacks configurability and NanoStar size, while SN74LVC1T45DBVR provides stronger drive and true bidirectionality but requires additional control signals and occupies 3× more board area.

FAQ
What logic functions can the SN74AUP1T57YZPR implement?
The SN74AUP1T57YZPR supports nine configurable logic functions: 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. Configuration is achieved by hardwiring pins A, B, and C to VCC or GND per the Function Selection Table in the datasheet - no external programming or configuration registers are required.
Does the SN74AUP1T57YZPR support bidirectional voltage translation?
No, the SN74AUP1T57YZPR is a unidirectional translator: inputs A, B, C accept logic levels (1.8 V, 2.5 V, or 3.3 V), and output Y drives at VCC level (2.3–3.6 V). It does not auto-detect direction or support true bidirectional data flow like bus transceivers. For bidirectional I²C or data bus translation, consider SN74LVC1T45DBVR instead.
What is the purpose of the Schmitt-trigger input in the SN74AUP1T57YZPR?
The Schmitt-trigger input in the SN74AUP1T57YZPR provides hysteresis (ΔVT = 210 mV) to reject noise and ensure clean switching on slow or noisy signals - especially valuable in mixed-signal designs with analog sensors, mechanical switches, or long PCB traces. It eliminates need for external RC filters and prevents metastability during marginal input transitions.
Can the SN74AUP1T57YZPR operate with VCC = 0 V?
Yes - the SN74AUP1T57YZPR features Ioff protection, allowing inputs and outputs to tolerate voltages from 0 V to 3.6 V even when VCC = 0 V, with leakage ≤ 0.5 µA. This enables safe hot-plug operation and partial-power-down modes in battery-backed systems, preventing back-current into powered-off sections of the circuit.
What is the package type and mounting compatibility of the SN74AUP1T57YZPR?
The SN74AUP1T57YZPR uses the NanoStar™ WCSP (YZP) package: 0.8 mm × 0.8 mm, 6-bump DSBGA with 0.4 mm pitch and 0.23-mm large solder bumps. It is RoHS-compliant, moisture-sensitivity Level-1, and compatible with standard reflow profiles. Board layout requires adherence to TI's recommended land pattern (SLAU271), with no thermal pad connection needed.
