Product details

Each timer can be configured for astable (oscillator) or monostable (one-shot) operation using external R and C components. The 4.5V to 16V supply range covers 5V logic, 12V industrial, and 15V analog rails. With a maximum oscillation frequency of 100 kHz, it handles audio tones, PWM generation, pulse-width modulation, relay timing delays, and missing-pulse detection in commercial-temperature (0°C to 70°C) environments. The 14-SSOP body (5.30 mm width) saves board area compared to the legacy 14-DIP or 14-SOIC packages.

The 4.5V to 16V supply range means this part can be dropped into a 5V TTL/CMOS design or a 12V/15V analog system without a separate regulator. The 20 mA supply current (per timer, typical) is the budget for the entire dual device — factor that into the rail's total load. If the board sees an engine bay, outdoor enclosure, or factory floor, you need the industrial-range sibling (NE556N or SA556).

Frequently asked questions

What is the difference between NE556DBR and NE556?

The NE556DBR is the surface-mount variant in a 14-SSOP package (5.30 mm width), while the NE556 typically refers to the 14-DIP through-hole package. The die and electrical specifications — dual 555 timer, 100 kHz, 4.5V to 16V supply, 0°C to 70°C — are the same. The DB suffix in the order code indicates the SSOP package.
