信号线保护IC-Maxim-MAX6816信号线保护IC
业内首款SOT开关去抖器，具有±15kV ESD保护和±25V故障容限
说明
The MAX6816/MAX6817/MAX6818 are single, dual, and octal switch debouncers that provide clean interfacing of mechanical switches to digital systems. They accept one or more bouncing inputs from a mechanical switch and produce a clean digital output after a short, preset qualification delay. Both the switch opening bounce and the switch closing bounce are removed. Robust switch inputs handle ±25V levels and are ±15kV ESD-protected for use in harsh industrial environments. They feature single-supply operation from +2.7V to +5.5V. Undervoltage lockout circuitry ensures the output is in the correct state upon power-up.
The single MAX6816 and dual MAX6817 are offered in SOT packages and require no external components. Their low supply current makes them ideal for use in portable equipment.
The MAX6818 octal switch debouncer is designed for data-bus interfacing. The MAX6818 monitors switches and provides a switch change-of-state output (active-low CH), simplifying microprocessor (μP) polling and interrupts. Additionally, the MAX6818 has three-state outputs controlled by an enable (active-low EN) pin, and is pin-compatible with the LS573 octal latch (except for the active-low CH pin), allowing easy interfacing to a digital data bus.
