APPLICATION INFORMATION

The inputs 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 is not damaged

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

−0.2 V and 4 V to ensure proper device operation.

To ensure reliable operation, the supply should be decoupled with a capacitor (0.1 μF) that is positioned as close

to the device as possible.

The TLC3702 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.
