FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3V245 is an 8-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 QS3V245 is specially designed for direct interface between 3.3V and
2.5V devices without any external components. When operating froma 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
CC
is less than
5
typical, providing near zero propagation delay through the switch.
Absence of DC path fromswitch I/O pins to V
CC
or ground makes QS3V245
an ideal device for hot swapping applications.
The QS3V245 is characterized for operation from-40
°
C to +85
°
