The MAX6818EAP+T from Maxim Integrated Products is a ±15KV ESD protected, octal, CMOS switch debouncers in 20 pin SSOP package. It provides clean interfacing of mechanical switches to digital systems. It accepts one or more bouncing inputs from a mechanical switch and produces a clean digital output after a short, preset qualification delay. Both switch opening bounce and switch closing bounce are removed. Robust switch inputs handle ±25V levels and are ±15KV ESD protected for use in harsh industrial environments. It features single supply operation from +2.7V to +5.5V. Undervoltage-lockout circuitry ensures the output is in correct state upon power-up. The MAX6818 monitors switches. Additionally, the MAX6818 has three state outputs controlled by an enable (active-low EN) pin. Typical applications include µP switch interfacing, industrial instruments, PC based instruments, portable instruments and membrane keypads.

• Switch debouncer integration simplifies system interface to mechanical switches
• No external components required, designed for data bus interfacing
• 6µA supply current, 40ms debounce duration
• Built-in protection circuitry improves system reliability
• Inputs can exceed power supplies up to ±25V
• ±15KV human body model, ±8KV IEC 1000-4-2 contact discharge, ±15KV IEC 1000-4-2 air gap discharge
• Direct data bus interface
• Pin compatible with LS573 octal latch (except for the CH pin)
• Switch change of state output (active-low CH), simplifying microprocessor polling and interrupts
• Operating temperature range form -40°C to +125°C
