Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.

Applications Information

Power-Supply Sequencing and

Overvoltage Protection

Do not exceed the absolute maximum ratings becausestresses beyond the listed ratings may cause perma-nent damage to the devices.

Proper power-supply sequencing is recommended forall CMOS devices. Always apply V+ before applyinganalog signals or logic inputs, especially if the analogor logic signals are not current limited. If this sequenc-ing is not possible, and if the analog or logic inputs arenot current limited to 20mA, add a small-signal diode(D1) as shown in Figure 1. If the analog signal can dipbelow GND, add D2. Adding protection diodesreduces the analog signal range to a diode drop (about0.7V) below V+ (for D1), and to a diode drop aboveground (for D2). Leakage is unaffected by adding thediodes. On-resistance increases by a small amount atlow supply voltages. Maximum supply voltage (V+)must not exceed 6V.

Adding protection diodes causes the logic thresholdsto be shifted relative to the power-supply rails. This canbe significant when low supply voltages (+5V or less)are used. With a +5V supply, TTL compatibility is notguaranteed when protection diodes are added. DrivingIN1 and IN2 all the way to the supply rails (i.e., to a

Figure 1. Overvoltage Protection Using Two External BlockingDiodes

diode drop higher than the V+ pin, or to a diode droplower than the GND pin) is always acceptable.

Protection diodes D1 and D2 also protect against someovervoltage situations. With Figure 1’s circuit, if the sup-ply voltage is below the absolute maximum rating, andif a fault voltage up to the absolute maximum rating isapplied to an analog signal pin, no damage will result.
