Product details
Overview
SN74AUP1G57DCKT from Texas Instruments is a low-power configurable multiple-function logic gate in SC70-6 package, supporting AND, OR, NAND, NOR, XNOR, inverter, and noninverter functions via 3-bit input configuration (In2/In1/In0 → Y). It operates from 0.8 V to 3.6 V, delivers 5.3 ns max propagation delay at 3.3 V, features Schmitt-trigger inputs, and supports partial-power-down mode via Ioff. It is used in portable medical devices and point-to-point signal conditioning.
For engineers reviewing the SN74AUP1G57DCKT datasheet, SN74AUP1G57DCKT pinout, SN74AUP1G57DCKT application, or SN74AUP1G57DCKT equivalent, key selection criteria include its ultra-low ICC (0.9 μA max), 1.5 pF typical input capacitance, 3.6-V I/O tolerance for mixed-voltage interfacing, and configurable logic functionality without external reprogramming.
Technical Context
The SN74AUP1G57DCKT implements a single configurable gate using CMOS technology with Schmitt-trigger inputs that provide hysteresis (ΔVT up to 1.31 V at 3 V) for noise immunity and robust handling of slow-rising signals. Its function table defines eight output states based on the binary combination of In2, In1, and In0 - enabling hardware-selectable logic behavior without firmware.
It supports partial-power-down operation: when VCC = 0 V, Ioff limits leakage to ≤0.6 μA, preventing backflow current in battery-backed or hot-swap systems. The device is optimized for 3.3-V operation but maintains full functionality down to 0.8 V, making it suitable for voltage translation between legacy 3.3-V peripherals and modern sub-1.2-V microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interface between 1.0-V SoCs and 3.3-V I/O rails without level shifters. |
| Max Propagation Delay | 5.3 ns at 3.3 V, CL = 5 pF - sufficient for high-speed point-to-point control signaling in portable instrumentation. |
| Static Current (ICC) | 0.9 μA maximum - extends battery life in always-on sensor nodes and wearable health monitors. |
| Input Capacitance (Ci) | 1.5 pF typical - minimizes loading on high-impedance sources like piezoelectric sensors or RC timing networks. |
| Ioff Leakage | 0.6 μA maximum at 0 V VCC - ensures safe isolation during power sequencing in multi-rail systems. |
| Input Hysteresis (ΔVT) | Up to 1.31 V at 3 V - rejects EMI and contact bounce in mechanical switch debouncing applications. |
| I/O Voltage Tolerance | 3.6-V tolerant inputs/outputs - allows connection to 3.3-V buses while powered from lower VCC (e.g., 1.2 V). |
Pinout & Package
SN74AUP1G57DCKT uses the SC70-6 (DCK) package, measuring 2.10 mm × 2.00 mm × 0.90 mm, with standard lead finish (NiPdAu) and moisture sensitivity level (MSL) 1 (unlimited floor life at ≤30°C/60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| In1 (Pin 1) | Logic input 1 | One of three configurable address inputs determining logic function; accepts 0–3.6 V regardless of VCC. |
| GND (Pin 2) | Ground reference | Primary return path for all internal circuitry and output current; must be low-impedance for noise immunity. |
| In0 (Pin 3) | Logic input 0 | LSB of 3-bit function select; tied to VCC/GND to fix logic mode during power-up. |
| Y (Pin 4) | Configurable logic output | Single-ended CMOS output capable of ±4 mA drive at 3 V; compatible with 1.8-V, 2.5-V, and 3.3-V receivers. |
| VCC (Pin 5) | Power supply | Supplies core logic and output drivers; requires local 0.1-μF bypass capacitor placed within 2 mm. |
| In2 (Pin 6) | Logic input 2 | MSB of 3-bit function select; determines whether output inverts, buffers, or performs combinational logic per truth table. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable logic function | Hardware-selectable AND/OR/NAND/NOR/XNOR/inverter/noninverter via static In2:In1:In0 state - eliminates need for multiple fixed-function gates. |
| Schmitt-trigger inputs | Hysteresis (ΔVT ≥ 0.53 V at 2.3 V) enables reliable switching with slow or noisy inputs - ideal for pushbutton interfaces and analog sensor thresholds. |
| Ultra-low power consumption | ICC ≤ 0.9 μA max across full VCC range - reduces quiescent load in battery-powered field transmitters and CPAP controllers. |
| Partial-power-down support | Ioff ≤ 0.6 μA at VCC = 0 V - prevents back-current damage when SN74AUP1G57DCKT is unpowered but connected to active bus lines. |
| Mixed-voltage I/O tolerance | Inputs and outputs tolerate up to 3.6 V independent of VCC - simplifies voltage translation in heterogeneous subsystems (e.g., 1.1-V MCU + 3.3-V display interface). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G57DCKT | Higher ICC (max 10 μA), no Schmitt inputs, 1.65–5.5-V VCC range, no Ioff | Not suitable for partial-power-down or noisy input environments; better for 5-V legacy systems | Select only if operating above 1.65 V and noise immunity is not required. |
| 74AHC1G57SE-7 | Same 3.3-V optimized performance, but SOT-353 (SC-70-5) package lacks dedicated GND pin - shares pin with In0 | Requires board redesign due to different pinout and reduced noise margin from shared pin | Use only when footprint compatibility is confirmed and ground integrity can be maintained. |
Compared with SN74LVC1G57DCKT and 74AHC1G57SE-7, the SN74AUP1G57DCKT uniquely combines ultra-low ICC, Schmitt-trigger inputs, and Ioff in a standard SC70-6 footprint - making it the only choice for battery-critical, noise-prone, or multi-rail hot-swap designs.

FAQ
What logic functions does the SN74AUP1G57DCKT support?
The SN74AUP1G57DCKT supports seven configurable logic functions - AND, OR, NAND, NOR, XNOR, inverter, and noninverter - selected by the static voltage states of its three inputs (In2, In1, In0). Each unique 3-bit combination maps to a defined output in the function table. No external programming or clocking is needed; configuration is purely hardware-based at power-up or runtime.
Does the SN74AUP1G57DCKT require external pull-up or pull-down resistors?
No - the SN74AUP1G57DCKT does not require external pull-up or pull-down resistors on its inputs. All inputs (In2, In1, In0) may be directly tied to VCC or GND to establish a stable logic state for function selection. This eliminates BOM cost and board space associated with discrete resistors, and ensures deterministic behavior during power-up and brownout conditions.
Can the SN74AUP1G57DCKT operate with a 1.2-V supply?
Yes, the SN74AUP1G57DCKT is fully specified to operate at 1.2 V, with guaranteed performance including propagation delay (≤9.5 ns at CL = 5 pF), input thresholds (VT+ = 0.53 V, VT− = 0.26 V), and output drive (±1.1 mA). Its 0.8–3.6-V VCC range makes it ideal for interfacing with modern ultra-low-voltage microcontrollers and sensors commonly found in wearables and IoT edge nodes.
How does the Ioff feature of the SN74AUP1G57DCKT protect system-level circuits?
The Ioff feature of the SN74AUP1G57DCKT limits input/output leakage to ≤0.6 μA when VCC = 0 V, preventing damaging back-current flow through the device when it is unpowered but connected to live buses. This protects upstream drivers and downstream receivers during power sequencing, hot-swap events, or partial system shutdown - a critical capability in modular medical equipment and industrial control systems.
Is the SN74AUP1G57DCKT pin-compatible with other SC70-6 logic gates?
Yes, the SN74AUP1G57DCKT uses the standard SC70-6 (DCK) footprint and pinout defined by JEDEC MO-203, matching SN74AUP1G00DCKT, SN74AUP1G02DCKT, and other TI AUP single-gate variants. Pin 1 = In1, Pin 2 = GND, Pin 3 = In0, Pin 4 = Y, Pin 5 = VCC, Pin 6 = In2 - enabling drop-in replacement in existing layouts where logic function flexibility is added post-design.
