Product details
Overview
SN74AUP1T97DBVR 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 4 mA output drive - used in battery-powered IoT sensor interfaces and mixed-voltage MCU peripheral bridging.
For engineers reviewing the SN74AUP1T97DBVR datasheet, SN74AUP1T97DBVR pinout, SN74AUP1T97DBVR application, or SN74AUP1T97DBVR equivalent, key selection criteria include its 2.3 V–3.6 V supply range, nine programmable gate functions via static A/B/C input biasing, ultra-low static current (0.9 µA max), and SOT-23-6 package compatibility with space-constrained portable designs.
Technical Context
The SN74AUP1T97DBVR implements a single-output, three-input configurable logic block with Schmitt-trigger inputs enabling noise-immune signal conditioning across voltage domains. Its internal architecture accepts LVCMOS input thresholds (e.g., VIH = 1.19 V @ VCC = 3.3 V, VIL = 0.5 V) while driving outputs compliant with the same VCC rail.
Function selection is achieved by hard-wiring inputs A, B, and C to VCC or GND per Table 7-2 - enabling modes including 2-to-1 MUX, AND, OR, NAND, NOR, inverter, and buffer without external components. Ioff support allows safe operation with VCC = 0 V while inputs/outputs tolerate 0–3.6 V signals.
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 interruption |
| Logic Translation | 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V - enables interoperability between legacy low-voltage peripherals and modern 2.5/3.3 V controllers |
| Input Hysteresis | ΔVT = 210 mV - rejects high-frequency noise and stabilizes output during slow-rising/falling analog-coupled signals |
| Ioff Leakage | 0.5 µA max at VCC = 0 V - prevents back-powering and ensures safe partial power-down in hot-swap or sleep-mode applications |
| tpd (max) | 6.8 ns @ CL = 5 pF, VCC = 2.5 V, VI = 1.8 V - supports >100 MHz data rates in low-capacitance digital links |
| Output Drive | ±4 mA - reduces overshoot/undershoot on PCB traces up to 10 cm without series termination |
| ICC (max) | 0.9 µA @ TA = 25°C - extends battery life in always-on sensor nodes beyond 10 years at 1 µA average system current |
Pinout & Package
SOT-23-6 package (DBV), 2.9 mm × 1.6 mm body, 1.45 mm max height, lead-free NiPdAu finish, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Configurable logic input | Bias to VCC/GND to select function per Table 7-2; Schmitt-triggered for noise immunity |
| 2 (B) | Configurable logic input | Second control input for MUX, AND/OR/NAND/NOR configurations; same threshold specs as A |
| 3 (GND) | Ground reference | Return path for all internal circuitry; must be low-impedance to maintain noise margin |
| 4 (C) | Configurable logic input | Third input for full function selection (e.g., select line in 2:1 MUX); shares hysteresis and VIH/VIL |
| 5 (VCC) | Supply voltage | Single power rail (2.3–3.6 V); powers all logic and output stages; bypass capacitor required |
| 6 (Y) | Configurable logic output | Active-drive output (±4 mA); level-shifted to VCC; supports capacitive loads ≤30 pF |
Key Features
| Feature | Design Value |
|---|---|
| Nine configurable gate functions | Hardware-selectable logic (MUX, AND, OR, NAND, NOR, inverter, buffer) eliminates need for multiple discrete gates or FPGA resources |
| Schmitt-trigger inputs | 210 mV hysteresis ensures clean output transitions even with slow or noisy inputs from sensors or long traces |
| Ioff partial-power-down | 0.5 µA leakage at VCC = 0 V enables safe isolation of powered-off subsystems without signal contention |
| Ultra-low power consumption | 0.9 µA max ICC + 5 pF Cpd enables sub-µW dynamic power at 1 MHz - critical for coin-cell–powered devices |
| Wide voltage translation support | Validated 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V operation per JEDEC JESD8-12 - no external resistors or level-shifter ICs needed |

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 |
|---|---|---|---|
| SN74AUP1T98DBVR | Same AUP family, but implements dual independent translators (Y1/Y2) with shared A/B/C configuration - no single-output mode | Requires redesign if only one translated signal is needed; adds unnecessary channel complexity and 20% higher quiescent current | Select only when two simultaneous level-shifted signals are required; not a drop-in replacement for SN74AUP1T97DBVR |
| TXS0102DCUR | Auto-direction sensing, 2-channel, open-drain outputs; no Schmitt inputs; higher ICC (10 µA) and larger SC70-8 package | Cannot replace SN74AUP1T97DBVR in push-pull or noise-sensitive applications; lacks configurable logic functions | Choose only for I²C bus extension where direction control is automatic and noise immunity is secondary |
Compared with SN74AUP1T97DBVR, SN74AUP1T98DBVR offers dual-channel flexibility at the cost of increased layout area and static power, while TXS0102DCUR provides auto-direction capability but sacrifices Schmitt noise rejection and logic configurability - making SN74AUP1T97DBVR optimal for deterministic, low-noise, single-signal translation in space- and power-constrained designs.

FAQ
What voltage translation combinations does the SN74AUP1T97DBVR support?
The SN74AUP1T97DBVR supports 1.8 V ↔ 2.5 V and 1.8 V ↔ 3.3 V bidirectional translation when operated at VCC = 2.5 V or VCC = 3.3 V respectively. It does not support 2.5 V ↔ 3.3 V translation. Input thresholds are validated per JEDEC JESD8-12: VIH = 1.10 V min at VCC = 2.5 V and VIH = 1.19 V min at VCC = 3.3 V. The SN74AUP1T97DBVR achieves this using internal Schmitt-trigger input circuitry referenced to its single VCC rail.
How is logic functionality configured on the SN74AUP1T97DBVR?
Logic functionality on the SN74AUP1T97DBVR is configured by hard-wiring its three inputs - A, B, and C - to either VCC or GND. This static biasing selects among nine functions including 2-to-1 MUX, AND, OR, NAND, NOR, inverter, and noninverting buffer, as defined in Table 7-2 of the datasheet. No external clock or programming interface is required. The SN74AUP1T97DBVR retains its selected function until the biasing is physically changed.
Does the SN74AUP1T97DBVR support partial power-down operation?
Yes, the SN74AUP1T97DBVR supports partial power-down via its Ioff feature. When VCC = 0 V, the device blocks current flow between inputs and outputs, limiting leakage to ≤0.5 µA while allowing input/output voltages from 0 V to 3.6 V. This prevents back-powering of powered-down sections and ensures safe hot-insertion in modular systems. The SN74AUP1T97DBVR maintains this behavior across –40°C to 85°C.
What is the maximum capacitive load the SN74AUP1T97DBVR can drive reliably?
The SN74AUP1T97DBVR is characterized up to 30 pF load capacitance, with propagation delay specified at 5 pF, 10 pF, 15 pF, and 30 pF. At CL = 30 pF and VCC = 3.3 V, tpd remains ≤9.8 ns (–40°C to 85°C). Driving loads >30 pF may increase delay unpredictably and risk signal integrity degradation. For reliable operation, keep total trace + pin + receiver capacitance ≤30 pF. The SN74AUP1T97DBVR's 4 mA drive strength is optimized for this range.
Is the SN74AUP1T97DBVR pin-compatible with other packages in the AUP1T97 family?
No - the SN74AUP1T97DBVR uses the SOT-23-6 (DBV) package with 2.9 mm × 1.6 mm body size and Q3 pin-1 quadrant orientation. Other variants like SN74AUP1T97DCKR (SC-70) and SN74AUP1T97DRYR (SON) have different footprints, thermal characteristics, and tape-and-reel dimensions. While all share identical logic functionality and electrical specs, PCB layout must be redesigned for each package. The SN74AUP1T97DBVR requires its specific land pattern per TI DBV0006A outline.
