NE555D SOP-8 Timer IC — SMD Version of the Classic NE555
The NE555D is the surface-mount (SOP-8) version of the legendary NE555 timer IC. Operating from 4.5V to 16V with a 200mA output drive, it supports astable (oscillator), monostable (one-shot), and bistable (flip-flop) configurations — making it one of the most versatile ICs ever designed.

Operating Modes
- Astable — Free-running oscillator; frequency set by R1, R2, C: f = 1.44 / ((R1 + 2×R2) × C)
- Monostable — One-shot pulse; pulse width t = 1.1 × R × C
- Bistable — SR flip-flop using TRIG and RESET pins
Why Choose NE555D?
- SOP-8 SMD Package — Compact footprint for modern PCB designs
- 200mA Output — Directly drives LEDs, relays, and small motors
- Wide Supply Range — 4.5V–16V covers 5V, 9V, and 12V systems
- Proven Reliability — Billions deployed; extensive community support and reference designs
- Pack of 10 — Ideal for prototyping, kits, and small production
Typical Applications
- PWM signal generation for motor speed control and LED dimming
- Debounce circuits for mechanical switches
- Tone generators and audio oscillators
- Missing pulse detectors and watchdog timers
- Voltage-controlled oscillator (VCO) with control voltage on pin 5
- Delay timers for relay activation
FAQ
Q: What's the difference between NE555D and NE555P?
A: NE555D is SOP-8 (SMD); NE555P is DIP-8 (through-hole). Electrically identical.
Q: Can NE555D run at 3.3V?
A: No — minimum supply is 4.5V. Use TLC555 or LMC555 for 3.3V operation.
