Product details
Overview
SN74AUP1T58DCKR from Texas Instruments is a single-supply voltage-level translator IC with configurable logic 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), Ioff protection (0.5 µA at VCC = 0 V), 4 mA output drive, and operates across 2.3 V–3.6 V supply range. Used in mixed-voltage I/O interfacing between microcontrollers and peripherals in portable IoT sensors.
For engineers reviewing the SN74AUP1T58DCKR datasheet, SN74AUP1T58DCKR pinout, SN74AUP1T58DCKR application, or SN74AUP1T58DCKR equivalent, key selection criteria include its nine programmable gate configurations (NAND, OR, XOR, inverter, buffer), ultra-low static power (0.5 µA ICC), 2.5 ns typical propagation delay at 3.3 V/15 pF, SC-70-6 package footprint, and Ioff-enabled partial-power-down capability for battery-backed systems.
Technical Context
The SN74AUP1T58DCKR implements AUP ultra-low-power logic architecture optimized for battery-operated devices. Its Schmitt-trigger input stage provides 210 mV hysteresis (VT+ = 1.19 V / VT− = 0.5 V at VCC = 3.3 V), rejecting noise on slow-rising signals and ensuring clean output transitions in mixed-signal environments.
Logic configuration is achieved by hardwiring inputs A, B, and C to VCC or GND per the Function Selection Table - enabling nine discrete gate functions without external components. The device supports true bidirectional level translation without direction control pins, leveraging input threshold compatibility across 1.8 V, 2.5 V, and 3.3 V logic families.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation and configurable logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T57DBVR | Same AUP family, 2-input configurable gate (A/B only); no C input - supports only 6 logic functions | Lacks third input for complex gate selection; not suitable for XOR or noninverted buffer configurations | Select when only basic NAND/OR/AND/NOR functions needed and board space allows SOT-23-6 instead of SC-70-6 |
| SN74LVC1T45DBVR | Bidirectional auto-direction-sensing translator; no configurable logic; higher drive (32 mA); no Schmitt inputs | Requires no pin strapping but adds direction ambiguity risk on floating buses; lacks noise immunity for analog-adjacent use | Prefer for high-speed digital-only buses where direction sensing is acceptable and noise immunity is secondary |

FAQ
What logic functions can the SN74AUP1T58DCKR implement?
The SN74AUP1T58DCKR supports nine distinct logic functions determined by strapping inputs A, B, and C to VCC or GND: 2-input NAND, OR (both inputs inverted), AND (one input inverted), NOR (one input inverted), NAND (both inputs inverted), OR, XOR, inverter, and noninverted buffer. Each configuration is defined in the Function Selection Table of the SCES612H datasheet, and no external components are required to set the function.
Does the SN74AUP1T58DCKR require a direction-control signal?
No, the SN74AUP1T58DCKR does not require a direction-control signal. It performs bidirectional voltage translation inherently through its input threshold design - accepting 1.8-V LVCMOS inputs while operating from either 2.5-V or 3.3-V VCC, and driving compatible output levels without external control pins. This simplifies routing and eliminates timing constraints associated with direction strobes.
What is the maximum capacitive load the SN74AUP1T58DCKR can drive reliably?
The SN74AUP1T58DCKR is characterized up to 30 pF load capacitance, with typical propagation delay of 4.4 ns at VCC = 3.3 V and CL = 30 pF. Its 4 mA output drive strength ensures clean edges and minimal overshoot on PCB traces under this load. For loads exceeding 30 pF, external buffering or reduced slew-rate design is recommended to maintain signal integrity.
How does the Ioff feature of the SN74AUP1T58DCKR protect system-level power domains?
The Ioff feature limits input/output leakage to ≤0.5 µA when VCC = 0 V, preventing back-powering of inactive power rails and eliminating contention on shared buses during partial power-down. This allows subsystems like sensors or radios to remain powered while the host MCU sleeps - a critical capability for battery longevity in SN74AUP1T58DCKR-based wearable and remote monitoring designs.
Is the SN74AUP1T58DCKR pin-compatible with other members of the SN74AUP1Txx family?
No, the SN74AUP1T58DCKR is not pin-compatible with most other SN74AUP1Txx variants. While it shares the SC-70-6 (DCK) package with SN74AUP1T57DCKR, the pin assignments differ: SN74AUP1T58DCKR uses pins 1–2–4 for A–B–C inputs and pin 5 for Y output, whereas SN74AUP1T57DCKR assigns A–B–Y to pins 1–2–5. Always verify pinout against the specific device's datasheet before layout.
