NE555 / NE555D — SOP-8 SMD Timer IC
The NE555 is the world's most popular timer IC, and this listing provides the SOP-8 SMD surface-mount version (NE555D) — new and original parts. Ideal for compact PCB designs where the classic DIP-8 package is too large. Operates in astable, monostable, and bistable modes.

Why Choose NE555D SOP-8?
- ✅ SMD form factor — saves PCB space vs DIP-8, compatible with reflow soldering
- ✅ 200mA output — directly drives LEDs, small relays, and buzzers
- ✅ Wide voltage range — works from 4.5V to 16V (3.3V systems use TLC555)
- ✅ New & original — genuine NE555 grade, not SA555 or LM555 substitutes
- ✅ Industry-standard pinout — drop-in compatible with all NE555 circuit designs
Compatible With / Works With
- Arduino PWM signal generation (external oscillator for precise frequency)
- IR remote control carrier generation (38kHz astable)
- Servo motor PWM signal (1–20ms period monostable)
- LED flasher and blinker circuits
- Debounce circuits for mechanical switches
Typical Applications
- PWM Generation — motor speed control, LED dimming (astable mode)
- Pulse Generation — single-shot timer for relay control (monostable mode)
- Oscillator — clock signal for logic circuits, 38kHz IR carrier
- Missing Pulse Detector — watchdog timer for embedded systems
- Tone Generator — audio frequency buzzer and alarm circuits
FAQ
Q: What is the difference between NE555 and NE555D?
A: NE555D is the SOP-8 surface-mount package variant of the NE555. Electrically identical — only the package differs (DIP-8 vs SOP-8).
Q: Can NE555D work at 3.3V for Arduino/ESP32 circuits?
A: The NE555 minimum Vcc is 4.5V, so it is not suitable for 3.3V-only systems. Use TLC555 (1V–15V) or LMC555 (1.5V–15V) for 3.3V operation.
Q: What is the maximum frequency for NE555 in astable mode?
A: Approximately 500kHz–1MHz with small RC values. For higher frequencies, use a dedicated oscillator IC like NE556 or a crystal oscillator.
