What are the key features of MAX6816EUS+?
- Single-channel contact-bounce elimination with no external RC components required
- 2.7 V to 5.5 V CMOS supply range for 3.3 V and 5 V system compatibility
- Clean logic output guaranteed within 40 ms of switch actuation
- 4-pin SOT-143 package for minimal PCB footprint on UI boards
- CMOS output directly drives logic inputs without pull-up resistor
- Low quiescent current making it suitable for battery-powered devices
What is MAX6816EUS+ used for?
MAX6816EUS+ is used in consumer electronics, industrial control panels, and medical devices wherever a mechanical pushbutton, toggle switch, or keypad contact must be debounced without a microcontroller interrupt handler or RC filter. It is particularly valuable in low-power IoT nodes and wearables where firmware-based debounce wastes CPU cycles, and the 4-pin SOT-143 package fits easily next to a switch footprint on a compact PCB.

Frequently Asked Questions
How long does MAX6816EUS+ take to produce a clean output after a switch closure, and how does that compare to a software debounce delay?
MAX6816EUS+ guarantees a settled, bounce-free logic output within 40 ms of a switch press. A typical firmware-based debounce routine uses a 20 ms to 50 ms delay loop, but ties up the MCU or requires a timer interrupt. The hardware MAX6816EUS+ handles this asynchronously, freeing all CPU cycles for other tasks.
What supply voltage does MAX6816EUS+ require, and can it coexist with a mixed 3.3 V / 5 V logic board?
MAX6816EUS+ operates from 2.7 V to 5.5 V, so it functions correctly on both 3.3 V and 5 V logic rails. Its CMOS output swings rail-to-rail, providing a valid logic-high output above 2.4 V at 3.3 V supply, which meets the VIH threshold of most 3.3 V logic-family inputs without a voltage translator.
How many external passive components does MAX6816EUS+ require to debounce a switch, and what does that mean for BOM cost?
MAX6816EUS+ requires zero external capacitors or resistors for its debounce function; only the IC and the switch are needed in the signal path. Compared to an RC debounce network using 1 resistor and 1 capacitor, the MAX6816EUS+ eliminates 2 passives and the associated PCB pads, saving roughly 2 mm² of board area per switch node.
What is the PCB footprint of the SOT-143 package of MAX6816EUS+, and why is it preferred for wearable or IoT devices?
The SOT-143 body measures approximately 2.9 mm × 1.6 mm, occupying under 5 mm² of board area with its 4 leads. At that size it can be placed directly adjacent to a tactile-switch footprint on a wearable PCB, whereas a DIP or SOIC debouncer IC would require 10× to 30× more area and through-hole pads incompatible with modern SMT assembly.
