SN74S08D

Inverter Gates Overview

The SN74S08D is a quad 2-input positive-AND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74S (Schottky) logic series and is housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical characteristics include a maximum propagation delay of 7.5 ns at 5 V with a 50 pF load, a low-level output current capability of 20 mA, and a high-level output current of 1 mA. The component supports an operating temperature range from 0°C to +70°C.

Inverter Gates Feature Summary

• Integrates four independent 2-input AND gates within a single 14-pin SOIC package for space-efficient designs.
• Utilizes Schottky transistor technology to achieve high-speed switching performance with a typical propagation delay of 7.5 ns.
• Provides robust output drive capabilities with a low-level sink current of 20 mA suitable for standard TTL loads.

Inverter Gates Applications

• High-speed digital logic circuits requiring fast processing times
• Parallel data processing systems utilizing multiple logic channels
• Industrial control equipment operating within standard commercial temperature ranges

Inverter Gates Procurement Notes

Verify the specific suffix 'D' confirms the 14-pin SOIC package configuration. Confirm that the procurement channel provides original manufacturer documentation or traceability records. Ensure the component lot meets RoHS3 compliance standards if required by the final assembly specifications. Check for any obsolescence notices as this part may be subject to discontinuation.

Inverter Gates Selection Notes

Select the SN74S08D when Schottky speed is required alongside standard 5V operation. Compare against SN74LS08D for lower power consumption needs or SN74AS08D for faster propagation delays. Ensure the application board layout accommodates the SOIC footprint dimensions. Verify input logic levels match the source driver outputs within the specified 0.8V and 2V thresholds.

Inverter Gates Part Context

This component is part of the broader SN54/74S08 family of quadruple 2-input AND gates. It shares functional compatibility with other 74S series devices but offers distinct speed-power trade-offs compared to LS or HC variants. The device serves as a fundamental building block for complex combinational logic networks in legacy and industrial electronic systems.

Inverter Gates Replacement Considerations

SN74S08DR is a tape-and-reel variant of the same die and function. SN74S08DRE4 is the lead-free compliant version of the through-hole equivalent, though package differs. Parametric equivalents are available from Rochester Electronics.

Inverter Gates FAQ
