Product details
Overview
SN74AUP1G97DCKRE4 from Texas Instruments is a low-power configurable multiple-function logic gate in SC-70 (DCK) package, supporting 0.8 V to 3.6 V operation with Schmitt-trigger inputs, 5.6 ns max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and Ioff partial-power-down capability - used in battery-powered sensor interfaces and level-shifting control logic.
For engineers reviewing the SN74AUP1G97DCKRE4 datasheet, SN74AUP1G97DCKRE4 pinout, SN74AUP1G97DCKRE4 application, or SN74AUP1G97DCKRE4 equivalent, key selection criteria include configurable logic function selection (MUX/AND/OR/NAND/NOR/inverter/buffer), ultra-low static current (0.9 mA max ICC), 3.6-V I/O tolerance for mixed-voltage systems, and validated SC-70 thermal performance (θJA = 259°C/W).
Technical Context
The SN74AUP1G97DCKRE4 implements a 3-input configurable logic cell where inputs A, B, and C select one of eight output functions via truth table mapping. Its Schmitt-trigger inputs provide hysteresis (ΔVT = 0.27–1.31 V across VCC range) enabling robust noise immunity for slow or noisy digital signals.
It features Ioff circuitry that disables outputs during partial power-down, preventing backflow current when VCC = 0 V, and supports 3.6-V tolerant I/Os for seamless interfacing between 1.8-V, 2.5-V, and 3.3-V domains without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables single-supply operation across ultra-low-voltage microcontrollers and mixed-voltage I/O systems. |
| tpd (Max) | 5.6 ns at 3.3 V, CL = 5 pF - ensures timing-critical point-to-point signal routing in portable device control paths. |
| ICC (Max) | 0.9 mA at VCC = 3.6 V - delivers sub-1-mA static power for multi-year battery life in always-on IoT endpoints. |
| CI (Typ) | 1.5 pF - minimizes capacitive loading on driving gates and preserves signal integrity in high-speed, low-current traces. |
| ΔVT (Hysteresis) | 0.27 V (at 1.65 V) to 1.31 V (at 3 V) - rejects >100 mV of input noise without external filtering in industrial sensor nodes. |
| Ioff (Max) | 0.6 mA at VCC = 0 V - blocks damaging back-current during hot-swap or partial system shutdown in modular electronics. |
| IOH/IOL | ±4 mA at VCC = 3 V - drives standard CMOS loads directly without buffer amplification in compact PCB layouts. |
Pinout & Package
SN74AUP1G97DCKRE4 uses the SC-70 (DCK) 6-pin surface-mount package (2.0 mm × 1.25 mm, 0.95 mm height), optimized for space-constrained portable designs and compatible with standard reflow profiles (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Logic input A | Primary data or control input; participates in 3-bit function selection per truth table. |
| 2 (B) | Logic input B | Secondary data/control input; combined with A and C to define output logic behavior. |
| 3 (GND) | Ground reference | Return path for all internal logic and I/O currents; must be low-impedance for noise immunity. |
| 4 (C) | Function select input C | Configures logic mode (e.g., C=L selects MUX mode Y=B; C=H selects Y=A). |
| 5 (Y) | Configurable output | Single-ended CMOS output delivering selected logic function; supports 3.6-V I/O tolerance. |
| 6 (VCC) | Power supply | Supplies core logic and I/O buffers; decoupling capacitor (0.1 µF) required within 2 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable logic function | Selects MUX, AND, OR, NAND, NOR, inverter, or noninverting buffer via A/B/C inputs - eliminates need for multiple discrete gates. |
| Schmitt-trigger inputs | Input hysteresis (ΔVT ≥ 0.27 V) enables reliable switching with slow-rising signals from mechanical switches or analog comparators. |
| Ioff partial-power-down | Outputs enter high-impedance state when VCC = 0 V, preventing backfeed into powered subsystems during firmware updates or sleep modes. |
| 3.6-V I/O tolerance | Accepts inputs up to 3.6 V regardless of VCC (0.8–3.6 V), simplifying voltage translation in multi-rail embedded systems. |
| NanoStar™ packaging option | Available in YFP/YZP DSBGA packages (0.89 mm × 1.29 mm) for ultra-dense wearable and medical PCBs - not applicable to DCK variant. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G97DCKR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ vs. 0.5 µA typ at 1.8 V); no Ioff support. | Preferred for 5-V legacy systems; unsuitable for partial-power-down or sub-1-V operation. | Choose when interfacing with 5-V peripherals and lowest quiescent current is not critical. |
| 74AHC1G97SE-7 | Higher drive strength (±8 mA); faster tpd (3.5 ns @ 3.3 V); no Schmitt-trigger inputs; no Ioff. | Better for high-speed clock distribution but lacks noise immunity for sensor inputs. | Choose for timing-critical combinatorial logic where input slew rate exceeds 1 V/ns and power-down isolation is unnecessary. |
Compared with SN74LVC1G97DCKR and 74AHC1G97SE-7, the SN74AUP1G97DCKRE4 uniquely balances ultra-low power (0.9 mA max ICC), Schmitt-trigger noise rejection, and Ioff-enabled system-level power sequencing - making it optimal for battery-constrained, noise-prone, and modular power architectures.

FAQ
What logic functions does the SN74AUP1G97DCKRE4 support?
The SN74AUP1G97DCKRE4 supports eight configurable logic functions determined by its three inputs (A, B, C): 2-to-1 multiplexer, 2-input AND, 2-input OR with one inverted input, 2-input NAND with one inverted input, 2-input AND with one inverted input, 2-input NOR with one inverted input, 2-input OR, inverter, and noninverted buffer. The exact function is selected per the truth table in the official datasheet, and all inputs may be tied to VCC or GND to fix functionality.
Does the SN74AUP1G97DCKRE4 support partial power-down operation?
Yes, the SN74AUP1G97DCKRE4 includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow through the device during partial system shutdown. This feature is explicitly verified in the datasheet's ELECTRICAL CHARACTERISTICS table under Ioff (max 0.6 mA at VCC = 0 V), making SN74AUP1G97DCKRE4 suitable for hot-swap and modular power architectures.
What is the maximum propagation delay of the SN74AUP1G97DCKRE4 at 3.3 V?
The maximum propagation delay (tpd) of the SN74AUP1G97DCKRE4 is 5.6 ns at VCC = 3.3 V ± 0.3 V with CL = 5 pF and TA = –40°C to 85°C, as specified in the SWITCHING CHARACTERISTICS table. This value applies to transitions at any input (A, B, or C) to output Y and is measured under standardized load and waveform conditions defined in Figure 10 of the datasheet.
Can the SN74AUP1G97DCKRE4 operate below 1.0 V?
Yes, the SN74AUP1G97DCKRE4 is fully specified for operation down to 0.8 V VCC, with guaranteed performance including VIH/VIL thresholds, tpd, and ICC across the entire 0.8 V to 3.6 V range. At 0.8 V, the device delivers 23.1 ns max tpd (CL = 5 pF) and maintains 0.5 mA typical ICC - enabling compatibility with emerging sub-1-V microcontrollers and energy-harvesting power supplies.
Is the SN74AUP1G97DCKRE4 pin-compatible with other SC-70 logic gates?
No, the SN74AUP1G97DCKRE4 has a unique 6-pin SC-70 pinout (A-B-GND-C-Y-VCC) that differs from standard 6-pin SC-70 logic gates like SN74LVC1G08 (A-GND-Y-VCC-A-B). Pin assignments are confirmed in the "DCK PACKAGE (TOP VIEW)" diagram in the datasheet. Layout reuse requires verification against the specific SN74AUP1G97DCKRE4 footprint and land pattern.
