APPLICATION INFORMATION

The input should always remain within the supply rails in order to avoid forward biasing the diodes in the electrostatic

discharge (ESD) protection structure. If either input exceeds this range, the device will not be damaged as long as

the input current is limited to less than 5 mA. To maintain the expected output state, the inputs must remain within

the common-mode range. For example, at 25

to assure proper device operation.

To assure reliable operation, the supply should be decoupled with a capacitor (0.1-

µF) positioned as close to the

device as possible.

The TLC393 has internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested

under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling these devices, as exposure

to ESD may result in the degradation of the device parametric performance.
