Description

The SE555DR is a precision timing circuit (555 timer IC) from Texas Instruments, packaged in an SOIC-8 surface-mount form. It operates as a monostable or astable multivibrator, generating accurate time delays or oscillations.
Key Features:
- Wide voltage range: 4.5V to 16V.
- Adjustable timing from microseconds to hours.
- High output current (200mA), suitable for driving relays/LEDs.
- Temperature stability: ±0.005%/°C.
Applications:
- Pulse generation, timers, oscillators, and LED flashers.
The "DR" suffix denotes the SOIC-8 package. Compatible with NE555 but with improved performance.
For detailed specs, refer to the datasheet.
