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. ## Supply range and temperature grade — what they mean for your BOM 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. The 0°C to 70°C commercial temperature grade limits this part to indoor, office, or appliance environments. If the board sees an engine bay, outdoor enclosure, or factory floor, you need the industrial-range sibling (NE556N or SA556). ## Active lifecycle — no LTB risk, standard channel sourcing The NE556DBR carries an Active product status with ROHS3 compliance. For a BOM line that needs a dual 555 timer in a surface-mount SSOP footprint, this is a low-risk, long-horizon selection.","metaTitle":"NE556DBR Dual 555 Timer, 100 kHz, 14-SSOP","metaDescription":"NE556DBR is a dual 555-type timer/oscillator in a 14-SSOP package. 100 kHz max frequency, 4.5V to 16V supply, 0°C to 70°C.
