This device contains circuits protect inputs outputs against damage high static voltages electrostatic fields. These circuits have been qualified protect this device against electrostatic discharges (ESD) according MIL-STD-883C, Method 3015; however, precautions should taken avoid application voltage higher than maximum-rated voltages these high-impedance circuits. During storage handling, device leads should shorted together device should placed conductive foam. circuit, unused inputs should always connected appropriate logic voltage level, preferably either ground. Specific guidelines handling devices this type contained publication Guidelines Handling (ESDS) Devices Assemblies available from Texas Instruments.
PRODUCTION DATA information current publication date. Products conform specifications terms Texas Instruments standard warranty. Production processing does necessarily include testing parameters.
