Robust Switch Inputs
The switch inputs on the MAX6816/MAX6817/MAX6818
have overvoltage clamping diodes to protect against
damaging fault conditions. Switch input voltages
can safely swing ±25V to ground (Figure 3). Proprietary
ESD-protection structures protect against high
ESD encountered in harsh industrial environments,
membrane keypads, and portable applications.
They are designed to withstand ±15kV per the
IEC 1000-4-2 Air Gap Discharge Test and ±8kV per the
IEC 1000-4-2 Contact Discharge Test.
Since there are 63k
(typical) pullup resistors connect-
ed to each input, driving an input to -25V will draw
approximately 0.5mA (up to 4mA for eight inputs) from
the VCC supply. Driving an input to +25V will cause
approximately 0.32mA of current (up to 2.6mA for eight
inputs) to flow back into the VCC supply. If the total sys-
tem VCC supply current is less than the current flowing
back into the VCC supply, VCC will rise above normal
levels. In some low-current systems, a zener diode on
VCC may be required.
±15kV ESD Protection
As with all Maxim devices, ESD-protection structures
are incorporated on all pins to protect against electro-
static discharges encountered during handling and
assembly. The MAX6816/MAX6817/MAX6818 have
extra protection against static electricity. Maxim's engi-
neers have developed state-of-the-art structures to pro-
tect against ESD of ±15kV at the switch inputs without
