Product details
Overview
SN74AUP1T97DBVT 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 at VCC = 2.5 V or 3.3 V, featuring Schmitt-trigger inputs (ΔVT = 210 mV), Ioff protection (0.5 µA), and ultra-low static power (0.9 µA max). It enables compact logic-level bridging in battery-powered IoT sensor nodes interfacing 1.8-V MCUs with 3.3-V peripherals.
For engineers reviewing the SN74AUP1T97DBVT datasheet, SN74AUP1T97DBVT pinout, SN74AUP1T97DBVT application, or SN74AUP1T97DBVT equivalent, key selection criteria include its 6-pin SOT-23 package, 2.3–3.6 V supply range, nine programmable gate functions via input biasing, sub-3 ns propagation delay (CL = 5 pF), and Ioff support for partial-power-down systems.
Technical Context
The SN74AUP1T97DBVT implements a single-output, three-input configurable logic block using AUP ultra-low-power CMOS technology. Its Schmitt-trigger inputs provide hysteresis (VT+ = 1.19 V / VT− = 0.5 V at VCC = 3.3 V) to reject noise on slow-rising signals and ensure clean output transitions in mixed-signal environments.
Logic configuration is achieved by hard-wiring inputs A, B, and C to VCC or GND per the Function Selection Table, enabling nine discrete functions-including 2-to-1 MUX, AND, OR, NAND, NOR, inverter, and buffer-without external components. Ioff allows safe operation with VCC = 0 V while inputs/outputs tolerate 0–3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - accommodates battery voltage droop in portable systems without functional loss |
| Input Threshold Hysteresis | 210 mV (ΔVT) - rejects noise on analog-digital interface lines and stabilizes switching in noisy PCB layouts |
| tpd (max) | 6.8 ns @ CL = 5 pF, VCC = 2.5 V, VI = 1.8 V - supports >100 MHz data rates in level-shifted control paths |
| Ioff Leakage | 0.5 µA max @ VCC = 0 V - enables hot-plug capability and prevents back-powering in powered-down subsystems |
| ICC (max) | 0.9 µA @ TA = 25°C - extends battery life in always-on sensor wake-up circuits and low-duty-cycle telemetry |
| ESD Rating | 2000 V HBM - meets industrial I/O robustness requirements without external protection diodes |
| Output Drive | ±4 mA - reduces signal overshoot/undershoot on short PCB traces without series termination |
Pinout & Package
SOT-23-6 (DBV) package: 2.9 mm × 1.6 mm body, 1.45 mm max height, JEDEC MO-178 compliant, tape-and-reel (250 pcs/reel), RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable logic input | Biasing A to VCC/GND selects one of nine logic functions; accepts 0–3.6 V regardless of VCC state |
| 2 (B) | Configurable logic input | Second logic input; shares same voltage tolerance and Schmitt-trigger behavior as Pin 1 |
| 3 (GND) | Ground reference | Primary return path for VCC current and logic thresholds; must be low-impedance for noise immunity |
| 4 (Y) | Configurable logic output | Single-ended CMOS output with 4 mA drive; VOH/VOL specified down to VCC = 2.3 V |
| 5 (C) | Configurable logic input | Third logic input; determines function mode (e.g., select line in 2:1 MUX configuration) |
| 6 (VCC) | Supply voltage | Single power rail defining output logic levels; powers internal bias network and enables Ioff when at 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Nine configurable gate functions | Eliminates need for multiple discrete logic ICs; enables hardware-programmable logic in space-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP1T98DBVT | Dual-channel version with independent A/B inputs and Y/Z outputs; identical VCC range and Ioff spec | Required when two independent level-shifted signals must be routed (e.g., I²C SDA/SCL); occupies same board area but doubles channel count | Select SN74AUP1T98DBVT only if dual-channel operation is needed; SN74AUP1T97DBVT saves cost and layout space for single-signal use cases |
| TXB0101DBVR | Auto-direction sensing; no configuration pins; higher ICC (10 µA typical); supports 1.2–3.6 V VCCA/VCCB rails | Preferred for bidirectional buses like I²C where direction changes dynamically; unsuitable for fixed-function logic configuration | Choose TXB0101DBVR for automatic bidirectional translation; SN74AUP1T97DBVT is superior for static, programmable unidirectional logic with lower power and noise immunity |
Compared with SN74AUP1T98DBVT and TXB0101DBVR, SN74AUP1T97DBVT uniquely combines ultra-low power, Schmitt-trigger noise rejection, and hardware-configurable logic in a single-channel SOT-23 package-making it optimal for deterministic, low-noise, space-constrained level-shifting tasks where direction is fixed and power budget is critical.

FAQ
What logic functions can the SN74AUP1T97DBVT implement?
The SN74AUP1T97DBVT supports nine distinct logic functions-including 2-to-1 multiplexer, 2-input AND/OR/NAND/NOR gates (some with inverted inputs), inverter, and noninverting buffer-by connecting inputs A, B, and C to VCC or GND per the Function Selection Table. Each configuration is static and hardware-defined; no programming or clock required. The SN74AUP1T97DBVT achieves this with zero external components, leveraging internal bias networks and Schmitt-trigger inputs for reliable operation.
Does the SN74AUP1T97DBVT support bidirectional voltage translation?
No, the SN74AUP1T97DBVT is a unidirectional voltage translator: inputs A/B/C accept 0–3.6 V logic levels, while output Y is referenced to VCC and swings between 0 V and VCC. It does not auto-detect direction like bus transceivers (e.g., TXB0101). However, it supports bidirectional *signal flow* in applications where the same physical line carries data in both directions under system control-provided external logic manages enable sequencing. The SN74AUP1T97DBVT maintains strict input/output isolation and Ioff protection regardless of VCC state.
What is the maximum operating temperature for the SN74AUP1T97DBVT?
The SN74AUP1T97DBVT is rated for continuous operation from –40°C to +85°C ambient temperature, validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life standards. Its thermal resistance (RθJA = 165°C/W for DBV package) ensures junction temperatures remain within safe limits under typical PCB copper pour conditions. This makes the SN74AUP1T97DBVT suitable for industrial enclosures and automotive cabin environments where ambient extremes occur.
Can the SN74AUP1T97DBVT operate with VCC = 0 V?
Yes-the SN74AUP1T97DBVT features Ioff circuitry that actively disables internal conduction paths when VCC = 0 V. Under this condition, inputs and outputs tolerate voltages from 0 V to 3.6 V without damage or excessive leakage (<0.5 µA). This enables safe "hot insertion" into live backplanes and partial-power-down modes in modular systems. The SN74AUP1T97DBVT remains electrically inert until VCC is restored, preserving signal integrity and preventing back-powering of upstream circuits.
How does the Schmitt-trigger input improve noise immunity in the SN74AUP1T97DBVT?
The SN74AUP1T97DBVT's Schmitt-trigger inputs provide 210 mV hysteresis (ΔVT = VT+ − VT−), meaning the rising threshold (e.g., 1.19 V at VCC = 3.3 V) differs significantly from the falling threshold (e.g., 0.5 V). This prevents oscillation on slowly transitioning or noisy signals-such as those from mechanical switches, analog comparators, or long PCB traces-by ensuring clean, single-event output transitions. The SN74AUP1T97DBVT thereby eliminates need for external RC filtering or debounce firmware, reducing BOM count and improving real-time response.
