Diodes Incorporated 74AUP1G57DW-7

Overview

74AUP1G57DW-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in SOT363 package, supporting AND, OR, NAND, NOR, XNOR, inverter, and non-inverting buffer configurations via input pin states. It operates from 0.8V to 3.6V, features ±4mA output drive at 3.0V, Schmitt-trigger inputs (950mV typical hysteresis), and IOFF partial power-down protection. It is used in voltage-level shifting and battery-powered signal conditioning circuits.

For engineers reviewing the 74AUP1G57DW-7 datasheet, 74AUP1G57DW-7 pinout, 74AUP1G57DW-7 application, or 74AUP1G57DW-7 equivalent, key selection criteria include supply voltage flexibility (0.8–3.6V), input tolerance to 3.6V in mixed-voltage systems, low ICC (<0.9µA), and verified Schmitt-trigger noise immunity for slow-rising signals.

Technical Context

The device implements a 3-bit truth table with eight possible output states determined by A, B, and C inputs, enabling user-selectable logic functions without external programming. Its CMOS AUP process delivers ultra-low static and dynamic power consumption across the full operating voltage range.

IOFF circuitry actively disables outputs during power-down to prevent backflow current, while Schmitt-trigger inputs provide robust noise rejection-hysteresis ranges from 0.07V at 0.8V VCC to 1.31V at 3.0V VCC-making it suitable for interfacing with noisy or slow-edge microcontroller GPIOs.

FAQ

What logic functions can the 74AUP1G57DW-7 implement?

The 74AUP1G57DW-7 supports eight output states defined by its three inputs (A, B, C), enabling user-configurable implementation of AND, OR, NAND, NOR, XNOR, inverter, and non-inverting buffer functions. Configuration is achieved by hardwiring inputs to VCC or GND per the function selection table in DS36852; no external programming or clock is required.

Does the 74AUP1G57DW-7 support partial power-down operation?

Yes-the device integrates IOFF circuitry that automatically disables the output when VCC = 0V, preventing damaging back-current flow from live inputs into a powered-down system. Measured IOFF leakage is ≤±0.6µA over –40°C to +125°C, meeting stringent requirements for modular power architectures.

Can the 74AUP1G57DW-7 interface between different voltage domains?

Yes-its inputs tolerate up to 3.6V regardless of VCC setting (0.8V–3.6V), enabling direct connection to higher-voltage signals (e.g., 3.3V UART TX) while operating from a lower supply (e.g., 1.8V). This eliminates external level-shifting components in mixed-voltage designs.

Is the SOT363 package thermally adequate for continuous operation?

The SOT363 package has θJA = 371°C/W (JEDEC-standard test board), limiting max power dissipation to ~14mW at ΔT = 50°C ambient rise. With typical ICC < 1µA and dynamic CPD = 4.8pF, actual power remains well below this limit-even at 10MHz toggle rates-ensuring safe operation without heatsinking.
