Applications Information
Power-Supply Sequencing
and Overvoltage Protection
Do not exceed the absolute maximum ratings, 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 or logic inputs, especially if the analog or logic
signals are not current limited. If this sequencing is not
possible, and if the analog or logic inputs are not current
limited to 20mA, add a small-signal diode (D1) as shown
in Figure 1. If the analog signal can dip below GND, add
D2. Adding protection diodes reduces the analog signal
range to a diode drop (about 0.7V) below V+ (for D1),
and to a diode drop above ground (for D2). Leakage is
unaffected by adding the diodes. On-resistance increas-
es by a small amount at low supply voltages. Maximum
supply voltage (V+) must not exceed 13V.
Adding protection diodes causes the logic thresholds to
be shifted relative to the power-supply rails. This can be
significant when low supply voltages (+5V or less) are
used. With a +5V supply, TTL compatibility is not guar-
anteed when protection diodes are added. Driving IN1
and IN2 all the way to the supply rails (i.e., to a diode
drop higher than the V+ pin, or to a diode drop lower
than the GND pin) is always acceptable.
