74AXP2G3404GSH

Overview

The Nexperia 74AXP2G3404GSH is a low-power buffer and inverter featuring Schmitt-trigger inputs for tolerance to slow signal transitions. It operates across a wide supply voltage range of 0.7 V to 2.75 V with very low static power consumption (ICC = 0.6 µA max at 85°C). The device includes IOFF circuitry for partial power-down applications, preventing damaging backflow currents. It complies with JEDEC standards JESD8-12A.01 through JESD8-5A.01 and offers high noise immunity with ESD protection exceeding 2 kV HBM and 1000 V CDM.

Feature Summary

• Schmitt-trigger action on all inputs ensures tolerance to slower input rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Low input capacitance (CI = 0.5 pF typical) and low output capacitance (CO = 1.0 pF typical) support high-speed operation.
• High noise immunity compliant with multiple JEDEC voltage standards.

Applications

• Partial power-down applications requiring isolation during powered-down states
• Signal buffering and inversion in low-voltage digital systems
• Interfaces handling slow-rising or noisy input signals

Procurement Notes

Verify the specific suffix 'GSH' against the manufacturer's latest ordering information to confirm package type and tape/reel specifications. Confirm product status as the component may be subject to obsolescence notices. Ensure design compliance with the specified operating temperature range of -40°C to +85°C and supply voltage limits.

Selection Notes

Select this component for designs requiring ultra-low power consumption and operation below 1.8 V. The integrated Schmitt triggers make it suitable for noisy environments or interfaces with slow signal edges. Verify that the required drive current and propagation delay characteristics meet the system timing requirements at the target supply voltage.

Part Context

This part belongs to the 74AXP family of Si-Gate CMOS devices from Nexperia. The family is characterized by extremely low power dissipation and compatibility with various JEDEC standards across different voltage ranges. The 74AXP2G3404 specifically integrates one buffer and one inverter function within a compact XSON6 package.

Replacement Considerations

Check for direct substitutes such as 74AXP2G3404GMH or 74AXP2G3404GNH if package variations are acceptable. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
