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°C with V
DD
= 5 V, both inputs must remain between −0.2 V and 4 V
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.
