SN74S05N

Inverter Gates Overview

The SN74S05N is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74S Schottky TTL logic series. It features six independent inverters with open-collector outputs housed in a 14-pin PDIP package. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum low-level output current of 20mA. Propagation delay is specified at 7.5ns under conditions of 5V supply and 50pF load capacitance. Logic thresholds define a low level at 0.8V and a high level at 2V. The component functions reliably across an operating temperature range of 0°C to 70°C.

Inverter Gates Feature Summary

• Incorporates Schottky TTL technology for high-speed switching performance.
• Provides open-collector outputs suitable for wired-logic configurations and voltage level shifting.
• Contains six independent inverting channels within a single package.

Inverter Gates Applications

• Wired-AND logic implementation via open-collector interconnection
• Voltage level translation between different logic families

Inverter Gates Procurement Notes

Verify that the ordered part number matches SN74S05N exactly, ensuring the 'N' suffix indicates the plastic DIP package variant. Confirm compliance with RoHS3 specifications as stated in official documentation. Check datasheet revisions to ensure compatibility with specific design requirements regarding propagation delay and electrical characteristics. Validate supplier authenticity through authorized distribution channels to guarantee component reliability.

Inverter Gates Selection Notes

Select this component when high-speed inversion is required within standard TTL voltage constraints. The open-collector architecture allows flexibility in interfacing with loads requiring higher voltages or currents than standard TTL outputs provide. Consider the 7.5ns propagation delay for timing-critical applications. Ensure the design accommodates the 20mA sink capability of the open-collector outputs without exceeding thermal limits.

Inverter Gates Part Context

The SN74S05N is part of the broader 74S family, which utilizes Schottky diodes to prevent transistor saturation, thereby reducing storage time and improving switching speed compared to standard 74 series logic. It serves as a functional equivalent to other hex inverters but offers distinct performance characteristics due to its bipolar construction. This component is widely used in legacy and industrial systems requiring robust TTL-compatible logic inversion.

Inverter Gates Replacement Considerations

SN74S05NE4 and SN74S05NG4 are confirmed lead-free and green variants of the same functional device. These substitutes maintain identical pinouts and electrical specifications while adhering to updated environmental standards. Verify package compatibility when substituting, as these variants may also be available in SOIC packages (e.g., SN74S05D) which require layout adjustments.
