Overview
The SN7404NSR is a standard logic inverter manufactured by Texas Instruments, featuring six independent inverters within a single package. It operates on a bipolar process technology and utilizes a push-pull output configuration. The device is housed in a 14-pin Small Outline Package (SOP) with tape-and-reel packaging. Recommended operating conditions specify a supply voltage range of 4.75 V to 5.25 V. Electrical characteristics at VCC = 5 V indicate a typical high-level output voltage of 3.4 V and a low-level output voltage of 0.4 V. Switching performance includes a typical propagation delay of 15 ns.
Feature Summary
- Contains six independent inverter circuits for signal inversion
- Utilizes a bipolar process technology with a push-pull output structure
- Designed for surface-mount assembly using a 14-pin SOP package
Applications
- Signal inversion in digital logic circuits
- Waveform shaping and pulse generation
- Clock signal conditioning
Procurement Notes
Verify the specific ordering suffix 'SR' corresponds to the tape-and-reel packaging format rather than tube packaging. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer documentation. Ensure the procurement channel provides valid traceability for the Texas Instruments manufacturing lot. Cross-reference the datasheet revision date against the current production status to confirm availability.
Selection Notes
Select this component when a standard TTL-compatible inverter is required for general-purpose logic applications. The SN7404NSR offers a balance of speed and drive capability suitable for driving multiple loads. Consider the 14-pin SOP package dimensions for PCB layout constraints. Evaluate the power dissipation requirements against the thermal impedance specifications provided in the datasheet.
Part Context
This part belongs to the SN54/7404 series of hex inverters produced by Texas Instruments. The 'SN' prefix denotes commercial temperature range operation, while the '74' indicates standard TTL logic family compatibility. The 'NSR' suffix specifies the plastic small-outline package type and the reel-based shipping method. This series is widely used in legacy and modern digital systems requiring basic logical inversion functions.
Replacement Considerations
Compatible substitutes include SN74LS04NSR and SN74S04NSR from the same manufacturer. Verify pinout compatibility and electrical parameter alignment before substitution.
