Programmable Timers and Oscillators

NE555DRG4 Description

The NE555DRG4 from Texas Instruments is a highly reliable 555-type single timer/oscillator IC designed for precision timing and pulse generation applications. Packaged in an 8-SOIC surface-mount format, it operates within a 4.5V to 16V supply range and delivers stable performance across a 0°C to 70°C temperature range. With a 10 mA supply current and a 100kHz frequency capability, this IC is optimized for low-power yet high-accuracy timing tasks. Although marked as Obsolete, it remains widely used due to its proven durability and compliance with ROHS3 and REACH Unaffected standards.

NE555DRG4 Features

• Wide Voltage Range (4.5V–16V): Ensures compatibility with diverse power supplies.
• Low Supply Current (10 mA): Enhances energy efficiency in battery-operated systems.
• High Frequency (100kHz): Suitable for rapid timing and oscillation requirements.
• Surface-Mount (8-SOIC): Compact and ideal for space-constrained PCB designs.
• Robust Compliance: Meets ROHS3 and REACH environmental standards.
• Moisture Sensitivity Level (MSL 1): Unlimited shelf life under typical storage conditions.

NE555DRG4 Applications

The NE555DRG4 excels in applications demanding precise timing control, such as:

• Pulse Width Modulation (PWM) Circuits: For motor speed control or LED dimming.
• Precision Oscillators: In clock generation for microcontrollers or sensors.
• Delay Timers: Used in industrial automation and safety systems.
• Waveform Generation: For square, triangular, or sawtooth waveforms in test equipment.
• Consumer Electronics: Timers in appliances, toys, and audio devices.

Conclusion of NE555DRG4

Despite its obsolete status, the NE555DRG4 remains a cornerstone in timing solutions due to its versatility, reliability, and ease of integration. Its wide voltage range, low power consumption, and high-frequency performance make it a preferred choice for engineers working on legacy systems or cost-sensitive designs. While newer alternatives exist, the NE555DRG4’s proven track record ensures its continued relevance in industrial, consumer, and prototyping applications.
