ZHCSIM9E November 2004 – August 2018 LMH6574
PRODUCTION DATA.
The LMH6574 is protected against electrostatic discharge (ESD) on all pins. The LMH6574 will survive 2000-V Human Body model and 200-V Machine model events. Under normal operation the ESD diodes have no effect on circuit performance. There are occasions, however, when the ESD diodes will be evident. If the LMH6574 is driven by a large signal while the device is powered down the ESD diodes will conduct . The current that flows through the ESD diodes will either exit the chip through the supply pins or will flow through the device, hence it is possible to power up a chip with a large signal applied to the input pins. Using the shutdown mode is one way to conserve power and still prevent unexpected operation.
