SN7404NE4

Overview

The SN7404NE4 is a standard TTL hex inverter manufactured by Texas Instruments. It contains six independent inverters housed in a 14-pin PDIP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 70°C. Electrical characteristics include a high-level output current of -0.4 mA, a low-level output current of 16 mA, and a typical propagation delay of 15 ns at 5 V.

Feature Summary

• Contains six independent inverter circuits for signal inversion
• Standard TTL logic family with defined input/output voltage thresholds
• Totem-pole output configuration for active drive states

Applications

• Digital logic signal inversion
• Clock signal generation and conditioning
• Logic level translation between stages

Procurement Notes

Verify the part number suffix NE4 indicates lead-free composition and RoHS compliance. Confirm the manufacturer is Texas Instruments and the package type matches the required PCB footprint. Ensure the orderable status is Active as listed in the official documentation.

Selection Notes

Select this component when six independent inverters are required in a single package. Verify that the circuit design accommodates the specific TTL input and output current limits. Ensure the operating environment remains within the specified commercial temperature range.

Part Context

This device belongs to the SNx404 series of hex inverters from Texas Instruments. It is functionally compatible with other variants such as SN74LS04 and SN74S04, though electrical parameters differ. The 'N' suffix denotes the plastic dual-in-line package.
