FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS32XV245 is a 16-bit high speed bus switch controlled by LVTTL-
compatible active low enable signal. When closed, the switches exhibit near zero
propagation delay without generating additional ground bounce or switching
noise.
The QS32XV245 is specially designed for direct interface between 3.3V and
2.5V devices without any external components. When operating from a 3.3V
supply,thelogichighlevelattheswitchoutputisclampedto2.5Vwhentheswitch
input signal exceeds 2.5V. This device can be used for switching 2.5V buses
without signal attenuation. The ON resistance at 3.3V VCC is less than 5Ω typical,
providing near zero propagation delay through the switch. Absence of DC path
from switch I/O pins to VCC or ground makes QS32XV245 an ideal device for
hot swapping applications.
The QS32XV245 is characterized for operation from -40°C to +85°C.
