A5191HRT_11 ONSEMI [ON Semiconductor], A5191HRT_11 Datasheet - Page 2

• Manufacturer Part Number: A5191HRT_11
• Description: HART Modem
• Manufacturer: ONSEMI [ON Semiconductor]

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. CMOS devices are damaged by high−energy electrostatic discharge. Devices must be stored in conductive foam or with all pins shunted.
2. Remove power before insertion or removal of this device.
