74AHCU04PW,118

Overview

The Nexperia 74AHCU04PW,118 is a high-speed Si-gate CMOS hex unbuffered inverter specified in compliance with JEDEC standard No. 7A. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features balanced propagation delays, low power dissipation, and inputs that accept voltages higher than VCC. Static characteristics include input leakage currents up to 2.0 μA and supply currents up to 40 μA at maximum voltage. Dynamic performance shows typical propagation delays of 3.0 ns at 3.3 V and 2.4 ns at 5.0 V with 15 pF load capacitance.

Feature Summary

• High-speed Si-gate CMOS technology compatible with Low-power Schottky TTL (LSTTL) pinouts
• Robust electrostatic discharge protection exceeding 2000 V via Human Body Model and 1000 V via Charge Device Model
• Unbuffered single-stage inverter architecture allowing for linear amplifier and oscillator applications

Applications

• Linear amplifier circuits utilizing open-loop gain characteristics
• Crystal oscillator designs requiring specific feedback components
• General-purpose digital logic inversion in mixed-voltage systems

Procurement Notes

Verify the exact ordering suffix matches the required package variant, as the PW designation specifically indicates the TSSOP14 plastic thin shrink small outline package. Confirm the temperature grade corresponds to industrial specifications (-40 °C to +125 °C). Ensure compatibility with existing PCB footprints defined by SOT402-1 outlines before finalizing procurement orders.

Selection Notes

Select this component when unbuffered signal inversion is required for analog or oscillating applications rather than standard digital buffering. The device suits designs needing operation across wide supply voltages up to 5.5 V. Consider the TSSOP14 package constraints regarding thermal derating above 81 °C if operating near maximum power dissipation limits.

Part Context

This part belongs to the 74AHCU04 series of hex unbuffered inverters manufactured by Nexperia USA Inc. It represents a specialized subset of the broader 74AHC logic family, distinguished by its lack of output buffering. This configuration enables unique functionalities such as linear amplification and crystal oscillation, differentiating it from buffered counterparts like the 74AHCT04.

Replacement Considerations

The 74AHCU04D serves as a direct functional substitute housed in the SO14 package. Designers must verify footprint compatibility between the TSSOP14 and SO14 packages during replacement planning.
