TLC552C
DUAL LINCMOS™ TIMER
SLFS046 – FEBRUARY 1984 – REVISED MAY 1988
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.
