Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum rat-
ings because stresses beyond the listed ratings
may cause permanent damage to the devices.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals, especially if the analog signal is not cur-
rent limited. If this sequencing is not possible, and if the
analog inputs are not current limited to <20mA, add a
small-signal diode (D1) as shown in Figure 1. If the ana-
log signal can dip below GND, add D2. Adding protec-
tion diodes reduces the analog range to a diode drop
(about 0.7V) below V+ (for D1), and a diode drop above
ground (for D2). On-resistance increases slightly at low
supply voltages. Maximum supply voltage (V+) must not
exceed +6V.
Adding protection diode D2 causes the logic threshold
to be shifted relative to GND. TTL compatibility is not
guaranteed when D2 is added.
Protection diodes D1 and D2 also protect against some
overvoltage situations. With Figure 1
’
s circuit, if the sup-
ply voltage is below the absolute maximum rating, and
if a fault voltage up to the absolute maximum rating is
applied to an analog signal pin, no damage will result.

Logic Input (MAX4702)
The MAX4702 features a V

logic input that allows for
lower logic input thresholds down to 1.0V min for V

in
the quad SPDT configuration. Power-up V

after V+ has
been powered with a minimum of 1.5V to ensure proper
operation of the device.
