SN74HC04NE4

Overview

The SN74HC04NE4 is a hex inverter manufactured by Texas Instruments, featuring six independent inverters within a single package. It operates on a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device utilizes standard CMOS inputs and balanced push-pull outputs, providing high-level output currents up to -4 mA and low-level output currents up to 4 mA at 4.5 V. Propagation delay ranges from 8 ns to 20 ns depending on the supply voltage. It is housed in a 14-pin PDIP package.

Feature Summary

• Contains six independent inverters performing Boolean function Y = A
• Features buffered standard CMOS inputs with high impedance characteristics
• Provides balanced CMOS push-pull outputs for similar sourcing and sinking capabilities
• Supports fanout up to 10 LSTTL loads

Applications

• Synchronizing inverted clock inputs
• Debouncing switches
• Inverting digital signals

Procurement Notes

Verify the component matches the SN74HC04NE4 designation specifically, as ordering suffixes like 'E4' indicate lead-free status but do not alter the functional logic. Confirm the package type is PDIP-14 and that the manufacturer is Texas Instruments. Ensure the datasheet revision aligns with current specifications before finalizing procurement orders.

Selection Notes

Select this component when a design requires multiple independent signal inversion stages within a single integrated circuit. It is suitable for applications needing wide voltage operation between 2 V and 6 V. Consider the propagation delay limits and input transition rates to ensure compatibility with the system's timing requirements and signal integrity standards.

Part Context

This part belongs to the SNx4HC04 family of hex inverters produced by Texas Instruments. It is designed as a general-purpose logic gate for digital circuits. The device is part of the broader 74HC series, which offers significant power reduction compared to older LSTTL logic families while maintaining compatible pinouts and logical functions.

FAQ

How should unused inputs be handled?

Unused inputs must be terminated to either VCC or ground to prevent undefined operational states caused by floating voltages.

What is the maximum capacitive load recommended?

The device can drive a load with a total capacitance less than or equal to the maximum load listed in the Switching Characteristics, typically ensuring optimal performance with loads under 70 pF.
