NE555DRG4

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.
