Diodes Incorporated 74AUP1G57FW4-7

Overview

74AUP1G57FW4-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in X2-DFN1010-6 package, supporting AND, OR, NAND, NOR, XNOR, inverter, and buffer functions via input pin configuration. It operates from 0.8V to 3.6V, delivers ±4mA output drive at 3.0V, features Schmitt-trigger inputs (950mV typical hysteresis at V_CC = 3.0V), and supports partial power-down via IOFF. It is used in battery-powered portable electronics for voltage-level shifting and signal conditioning.

For engineers reviewing the 74AUP1G57FW4-7 datasheet, 74AUP1G57FW4-7 pinout, 74AUP1G57FW4-7 application, or 74AUP1G57FW4-7 equivalent, key selection criteria include supply voltage range (0.8–3.6V), IOFF-enabled power-down isolation, Schmitt-trigger noise immunity, ultra-low static current (<0.9µA), and DFN1010 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a programmable 3-input combinational logic cell where the output Y is determined by all eight possible input combinations of A, B, and C - enabling user-selectable Boolean functions without external components. Its Schmitt-trigger inputs provide robust noise rejection for slow-rising/falling signals, with hysteresis ranging from 0.07V (0.8V supply) to 1.31V (3.0V supply).

The IOFF circuit actively disables the output during partial power-down, blocking back-current flow when V_CC = 0V while inputs remain biased at 0–3.6V. Input tolerance up to 3.6V enables mixed-voltage interfacing between 1.2V, 1.8V, 2.5V, and 3.3V domains without level shifters.

FAQ

What logic functions can be implemented with the 74AUP1G57FW4-7?

The 74AUP1G57FW4-7 supports eight distinct logic configurations via its three inputs: 2-input AND, OR, NAND, NOR, XNOR, inverter, non-inverting buffer, and AND with both inputs inverted. The specific function is selected by hardwiring A, B, and C to V_CC or GND per the Function Selection Table in DS36852 Rev. 1–2, page 4.

Does the 74AUP1G57FW4-7 require external pull-up or pull-down resistors?

No. Unused inputs may be tied directly to V_CC or GND per Recommended Operating Conditions (DS36852 p.4). The device has no internal weak pull-ups/pull-downs, but Schmitt-trigger inputs tolerate floating conditions poorly - direct connection is mandatory for predictable operation.

Can the 74AUP1G57FW4-7 operate reliably at 0.8V supply?

Yes. It is fully characterized down to 0.8V: propagation delay is 28ns (typ) at CL=5pF, output drive is ±20µA, and input thresholds are VT+ = 0.3–0.65V / VT− = 0.1–0.6V. Static current remains <0.9µA, making it suitable for energy-harvesting and coin-cell applications.

Is the X2-DFN1010-6 package compatible with standard reflow profiles?

Yes. The X2-DFN1010-6 package complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and supports standard Pb-free reflow profiles (peak 260°C, 60s max above 217°C). Diodes' recommended pad layout (AP02001) ensures solder joint reliability and thermal dissipation.
