SN74LS27DRE4

Inverter Gates Overview

The SN74LS27DRE4 is a triple 3-input positive-NOR gate manufactured by Texas Instruments. It belongs to the LS (Low-power Schottky) logic family and operates within a supply voltage range of 4.75 V to 5.25 V. The device features a propagation delay of 10 ns at 5 V, with a low-level output current of 8 mA and a high-level output current of -400 µA. It is housed in a 14-pin SOIC package.

Inverter Gates Feature Summary

• Triple 3-input NOR logic functionality
• Low-power Schottky technology for reduced power consumption
• High noise immunity characteristics

Inverter Gates Applications

• Digital logic circuits requiring NOR operations
• Microprocessor systems interface logic
• General-purpose digital signal processing

Inverter Gates Procurement Notes

Verify the specific suffix 'RE4' against official Texas Instruments documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the component is not obsolete or discontinued before finalizing procurement plans, as availability may be limited for older LS series parts.

Inverter Gates Selection Notes

Select this component when designing circuits requiring three independent 3-input NOR gates with low-power dissipation. Ensure the design environment supports the standard 5V logic level requirements of the LS family. Consider pin compatibility if replacing existing designs using standard SOIC-14 packages.

Inverter Gates Part Context

This part is part of the Texas Instruments SN74xx series of logic gates. The SN74LS27 specifically provides triple 3-input NOR functions. It is designed for use in various digital applications where reliable logic switching is required under standard operating conditions.

Inverter Gates Replacement Considerations

Check for direct pin-compatible replacements such as other manufacturers' SN74LS27 variants. Verify electrical specifications match exactly, particularly propagation delay and output drive capabilities, to ensure circuit integrity during substitution.
