Texas Instruments SN74AUP1T58DSFR

Overview

SN74AUP1T58DSFR 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. It features Schmitt-trigger inputs (ΔVT = 210 mV), I_off protection (0.5 µA max at V_CC = 0 V), and operates across 2.3–3.6 V supply range. Used in mixed-voltage I/O interfacing between microcontrollers and peripherals in portable embedded systems.

For engineers reviewing the SN74AUP1T58DSFR datasheet, SN74AUP1T58DSFR pinout, SN74AUP1T58DSFR application, or SN74AUP1T58DSFR equivalent, key selection criteria include its nine programmable logic functions (NAND, OR, XOR, buffer, inverter), ultra-low static power (0.5 µA ICC), 6-pin X2SON package (1.05 × 1.05 mm, 0.4 mm height), and guaranteed operation from –40°C to +85°C.

Technical Context

The SN74AUP1T58DSFR implements AUP ultra-low-power logic technology optimized for battery-backed applications. Its three configurable inputs (A, B, C) are connected to V_CC or GND to select one of nine logic functions - including inverter, noninverting buffer, 2-input XOR, and NAND/NOR variants - without external components.

Schmitt-trigger inputs provide 210 mV hysteresis (VT+ = 1.19 V / VT− = 0.5 V at V_CC = 3.3 V), rejecting noise on slow-rising signals and ensuring clean output transitions. I_off enables partial power-down with leakage <0.5 µA when V_CC = 0 V, allowing safe signal routing across powered-off domains.

FAQ

What logic functions can the SN74AUP1T58DSFR be configured to perform?

The SN74AUP1T58DSFR supports nine distinct logic functions determined by biasing its A, B, and C inputs to V_CC or GND: 2-input NAND, 2-input OR with both inputs inverted, 2-input AND with inverted input, 2-input NOR with inverted input, 2-input NAND with both inputs inverted, 2-input OR, 2-input XOR, inverter, and noninverted buffer. Each configuration is defined in the Function Selection Table of the SCES612H datasheet.

Does the SN74AUP1T58DSFR support bidirectional voltage translation?

No - the SN74AUP1T58DSFR is a unidirectional translator: inputs A/B/C accept 1.8-V, 2.5-V, or 3.3-V logic levels, and output Y drives at the V_CC voltage (2.3–3.6 V). It does not support automatic direction sensing or true bidirectional data flow like bus transceivers. Signal direction must be architecturally fixed in the system design.

What is the maximum operating temperature range for the SN74AUP1T58DSFR?

The SN74AUP1T58DSFR is rated for continuous operation from –40°C to +85°C ambient temperature, as confirmed in the Recommended Operating Conditions table (Section 6.2) of the SCES612H datasheet. This range applies to the DSF package variant and is validated across production lots per TI's quality assurance protocols.

How does the I_off feature of the SN74AUP1T58DSFR protect system integrity during power-down?

When V_CC = 0 V, the SN74AUP1T58DSFR limits I_off leakage to ≤0.5 µA per input/output terminal, preventing parasitic power paths and back-powering of disabled subsystems. This allows safe connection of A/B/C/Y pins to live 3.6-V signals even with V_CC unpowered - a requirement for USB-C detachable accessories and hot-swap I/O modules using the SN74AUP1T58DSFR.

Can the SN74AUP1T58DSFR replace discrete logic gates such as 74AUP1G04 or 74AUP1G32?

Yes - the SN74AUP1T58DSFR can replace multiple discrete gates by configuring its A/B/C inputs to emulate specific functions: e.g., tying A=V_CC, B=GND, C=GND configures it as an inverter (replacing 74AUP1G04), while A=GND, B=GND, C=V_CC yields a 2-input OR gate (replacing 74AUP1G32). This consolidation reduces bill-of-materials count and PCB footprint without sacrificing performance or power efficiency.
