E4237 SEMTECH [Semtech Corporation], E4237 Datasheet - Page 18

• Manufacturer Part Number: E4237
• Description: Dual Channel Per-Pin Parametric Measurement Unit
• Manufacturer: SEMTECH [Semtech Corporation]

Warning: It is extremely important that the voltage on any
device pin does not exceed the range of VEE – 0.5 to VCC
+0.5V at any time, either during power up, normal
operation, or during power down. Failure to adhere to this
requirement could result in latchup of the device, which
could be destructive if the system power supplies are
capable of supplying large amounts of current. Even if
the device is not immediately destroyed, the cumulative
damage caused by the stress of repeated latchup may
affect device reliability.
