NE555 SMD Package Timer IC

NE555 SD Package Timer IC 

The NE555 is one of the most popular and versatile timer ICs ever produced, widely used in timing, pulse generation, oscillation, and delay circuits. In the SMD (surface-mount) package, it is ideal for compact and modern electronic designs while retaining the same reliable performance as the classic through-hole version.

The NE555 can operate in monostable, astable, and bistable modes, allowing it to generate accurate time delays, square waves, pulse-width modulation (PWM), and clock signals. It works over a wide supply voltage range and can both source and sink relatively high output current, making it suitable for directly driving LEDs, buzzers, and small loads.
