SN74AHC04QPWRQ1

Overview

The SN74AHC04QPWRQ1 is an automotive-grade hex inverter utilizing Texas Instruments' EPIC CMOS process. It operates within a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature from -40°C to +125°C. The device provides six independent inverters with high noise immunity and low static power consumption. Switching characteristics vary by voltage, with propagation delays ranging from approximately 3.8 ns to 13 ns depending on load capacitance and supply conditions.

Feature Summary

• Qualified for automotive applications using enhanced-performance implanted CMOS technology
• Provides six independent logic inverters for signal inversion functions
• Operates across a broad supply voltage range from 2 V to 5.5 V
• Supports extended industrial temperature environments up to 125°C

Applications

• Synchronizing inverted clock inputs
• Switch debounce circuits
• Digital signal inversion

Procurement Notes

Verify the specific package variant (PW, D, or BQA) matches the design requirements, as thermal resistance and pinout dimensions differ significantly between TSSOP, SOIC, and WQFN options. Confirm RoHS compliance and lead finish specifications against the orderable addendum. Ensure ESD handling protocols are strictly followed during assembly due to the sensitivity of CMOS inputs.

Selection Notes

Select this component when designing automotive systems requiring reliable digital inversion across wide voltage and temperature ranges. The AHC series offers superior speed compared to standard HC logic while maintaining compatibility with 5-V systems. Consider the specific package's thermal performance if multiple gates are active simultaneously, as junction-to-ambient resistance varies by housing type.

Part Context

This part belongs to the SN74AHC04-Q1 family of automotive hex inverters. It is functionally equivalent to the commercial SN74AHC04 but meets stricter automotive reliability standards. The 'Q1' suffix indicates qualification for automotive use, while 'PWR' specifically denotes the TSSOP-14 package variant.

FAQ

How should unused inputs be handled?

All unused inputs must be connected to either VCC or GND to prevent floating states that could cause undefined operation or excessive current consumption.

What is the maximum input transition rate?

The maximum input transition rise or fall rate is 20 ns/V at 5 V supply and 100 ns/V at 3.3 V supply to ensure proper switching characteristics.
