74AUP1G57FZ4-7

Overview

The Diodes Incorporated 74AUP1G57FZ4-7 is a single, 3-input positive configurable multiple-function gate featuring a standard push-pull output. Designed for operation with a power supply range of 0.8V to 3.6V, the device allows users to select logic functions including AND, OR, NAND, NOR, XNOR, inverter, or non-inverting buffer based on eight patterns of 3-bit input. It incorporates Schmitt trigger action at all inputs and IOFF circuitry for partial power-down applications.

Feature Summary

• Configurable Logic Functionality: Supports selection of AND, OR, NAND, NOR, XNOR, inverter, or non-inverting buffer via 3-bit input patterns.
• Schmitt Trigger Inputs: Provides tolerance for slower input rise and fall times through hysteresis.
• Partial Power-Down Support: IOFF circuitry disables the output to prevent damaging current backflow when powered down.
• Low Power Consumption: Features low static power consumption (ICC < 0.9µA) and low dynamic power consumption.

Applications

• Battery and Low-Power Needs
• Voltage Level Shifting
• General Purpose Logic
• Power Down Signal Isolation

Procurement Notes

Verify the package type matches the required footprint, as the FZ4 suffix denotes the X2-DFN1410-6 package. Confirm RoHS compliance and lead-free status if required by assembly specifications. Check for any product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a single gate must perform multiple logic functions dynamically. Ensure the design accommodates the 0.8V to 3.6V supply range. Consider the X2-DFN1410-6 package dimensions for PCB layout. Verify that the input voltage levels are compatible with the 3.6V tolerant inputs for mixed-voltage environments.

Part Context

This part belongs to the 74AUP1G series of Advanced Ultra Low-Power CMOS logic devices from Diodes Incorporated. The 74AUP1G57 specifically provides a versatile configurable gate solution within a compact surface-mount package, suitable for space-constrained portable electronics and general-purpose digital logic applications requiring low power consumption.

Replacement Considerations

Check datasheets for other 74AUP1G57 variants with different package suffixes (e.g., W6, DW, FW3, FW4) if the X2-DFN1410-6 footprint is not mandatory. Ensure functional equivalence regarding configurable logic capabilities and electrical characteristics when substituting.

FAQ

How is the logic function determined?

The output state is determined by eight patterns of 3-bit input (A, B, C). Users can connect inputs to ground or Vcc to select specific functions like AND, OR, NAND, NOR, XNOR, inverter, or buffer.

What is the purpose of the IOFF feature?

The IOFF circuitry supports partial-power-down mode operation by disabling the output, which prevents damaging current backflow when the device is powered down.
