Discharge, and 15kV using the Human Body Model. Between All ICs:
8ns (MAX3095)
The MAX3095 operates from a +5V supply, while the
10ns (MAX3096)
MAX3096 operates from a +3.3V supply. Receiver prop-
agation delays are guaranteed to within 8ns of a pre-
Single +3V Operation (MAX3096)
determined value, thereby ensuring device-to-device
Single +5V Operation (MAX3095)
matching across production lots.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
