SN74LS30D

Inverter Gates Overview

The SN74LS30D is an open-collector NAND gate integrated circuit manufactured by onsemi. It operates within a TTL logic family and accepts an 8-input configuration per gate. The device is housed in a SOIC-14 surface-mount package. It functions with a DC supply voltage range of 4.75V to 5.25V, supporting a maximum propagation delay of 20ns at 5V. The component is rated for commercial operation between 0°C and 70°C.

Inverter Gates Feature Summary

• Provides high-speed logic switching capabilities through Low Power Schottky (LSTTL) circuitry
• Features open-collector outputs suitable for wired-AND configurations and interfacing with different logic families
• Designed for robust performance in commercial temperature environments

Inverter Gates Applications

• Digital logic circuits requiring multi-input NAND operations
• Wired-AND bus implementations
• Interface adapters between different voltage logic levels

Inverter Gates Procurement Notes

Verify the manufacturer marking matches onsemi specifications rather than Texas Instruments part numbers. Confirm the suffix 'D' indicates the SOIC-14 package type. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference datasheets from authorized distributors to confirm current production status.

Inverter Gates Selection Notes

Select this component when an 8-input NAND function is required in a compact surface-mount format. The open-collector output allows flexibility in pull-up resistor selection for various load conditions. Consider thermal dissipation limits and ensure adequate PCB layout for the SOIC-14 footprint during design integration.

Inverter Gates Part Context

This device belongs to the standard 74LS series of digital logic gates, widely used in general-purpose computing and control systems. The SN74LS30 variant specifically provides eight inputs into a single NAND gate structure, distinguishing it from lower-input variants like the SN74LS21 or SN74LS10.

Inverter Gates Replacement Considerations

Compatible substitutes include the SN74LS30N (PDIP package) and generic equivalents such as MC74LS30D. Verify pinout compatibility and electrical characteristics before substitution.
