description (continued)

These devices have internal electrostatic discharge (ESD) protection circuits that will prevent catastrophic

failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3105.2. However, care should be

exercised in handling these devices as exposure to ESD may result in a degradation of the device parametric

performance.

All unused inputs should be tied to an appropriate logic level to prevent false triggering.

The TLC552C is characterized for operation from 0

°C to 70°C.
