DESCRIPTION:
LVTTL-compatible active low enable signal. When closed, the switches exhibit
near zero propagation delay without generating additional ground bounce or
switching noise.
2.5V devices without any external components. When operating from a 3.3V
supply, the logic high level at the switch output is clamped to 2.5V when the switch
input signal exceeds 2.5V. This device can be used for switching 2.5V buses
without signal attenuation. The ON resistance at 3.3V V
providing near zero propagation delay through the switch. Absence of DC path
from switch I/O pins to V
hot swapping applications.
