MAX4914B Maxim, MAX4914B Datasheet - Page 3

• Manufacturer Part Number: MAX4914B
• Description: The MAX4914B/MAX4915A/B/MAX4917A/B family of switches feature internal current limiting to prevent damage to host devices due to faulty load conditions
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: All parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.
Note 2: Latchoff current does not include the current flowing into FLAG.
Note 3: The on-time is defined as the time taken for the current through the switch to go from 0mA to 10mA. The off-time is defined
Note 4: Retry time is typically 15 times the blanking time.
