NE555DRE4

Overview

The NE555DRE4 is a single timer integrated circuit manufactured by Texas Instruments, belonging to the NE555 family. It operates as a precision timer generator capable of producing accurate time delays or oscillation frequencies up to 100kHz. The device functions within a supply voltage range of 4.5V to 16V and draws a typical supply current of 10mA. It is housed in an 8-SOIC surface-mount package with a width of 3.90mm. The component is rated for operation within a temperature range of 0°C to 70°C and remains in active production status.

Feature Summary

• Single-channel 555-type timer/oscillator IC
• Operating frequency up to 100kHz
• Supply voltage range: 4.5V to 16V
• 8-SOIC (0.154", 3.90mm wide) surface-mount package

Applications

• Time delay generation
• Pulse generation circuits
• Logic clock signals

Part Context

The NE555DRE4 is the tape-and-reel variant of the NE555DR, sharing identical electrical specifications and pinout. The 'E4' suffix typically denotes specific packaging or environmental compliance attributes defined by Texas Instruments for bulk distribution. It serves as a direct functional equivalent to other NE555 series timers in standard timing applications.

Replacement Considerations

Compatible substitutes include the NE555DR and LM555 variants, provided they meet the 8-SOIC package requirement and operate within the 4.5V-16V supply range. Verify that replacement parts support the required 100kHz frequency and 0°C to 70°C operating temperature.
