Overview
The NE555DG4 is a single precision timer integrated circuit manufactured by Texas Instruments, belonging to the NE555 series. It operates within a supply voltage range of 4.5V to 16V and supports a maximum frequency of 100kHz. The device draws a supply current of 10mA and functions reliably across an operating temperature range of 0°C to 70°C. It is housed in an 8-SOIC package with a width of 3.90mm and utilizes surface-mount installation. This component serves as a monolithic timing system capable of generating precise time delays or oscillation.
Feature Summary
- Single 555-type timer/oscillator IC
- Supply voltage range: 4.5V to 16V

Procurement Notes
The NE555DG4 is identified as obsolete and no longer manufactured by Texas Instruments. Verification of current stock availability through authorized distributors is required before procurement planning. Alternative components from the same family or compatible pin-to-pin replacements should be evaluated for new designs.
Selection Notes
Select the NE555DG4 only for legacy board maintenance or repair where original specifications are mandatory. For new designs, consider active alternatives such as the LM555CM/NOPB or other commercial-grade 555 timers that offer similar electrical characteristics but remain in production. Ensure the 8-SOIC footprint matches the target PCB layout.
Part Context
The NE555DG4 is part of the broader NE555 family of precision timers. The 'D' suffix indicates the SOIC-8 package, while 'G4' typically denotes lead-free and RoHS compliance attributes specific to Texas Instruments manufacturing standards during its production lifecycle. It shares functional compatibility with standard NE555 devices.
Replacement Considerations
Public confirmed substitute part numbers include LM555CM/NOPB and NE555DR. These alternatives provide similar timing functionality and pin configurations, facilitating potential migration from the obsolete NE555DG4.
