TimerBlox parts operate from very low frequencies up to 2MHz. They operate on a supply voltage from 2.25V to 5.5V and require no crystal or timing capacitors. Also, the 20mA source and sink capability allows for directly driving opto-isolators and transformers for electrical isolation. Furthermore, TimerBlox parts offer a fast, first cycle accurate startup and power consumption ranging from 60µA to 250µA. The TimerBlox parts are available in a SOT23 or 2mm by 3mm DFN package. Additionally, all TimerBlox parts are offered in three temperature grades: 0°C to 70°C, -40°C to 85°C, and -40°C to 125°C.
