3.3V HIGH SPEED 32-BIT
MULTIWIDTH BUS SWITCH
DESCRIPTION:
The QS34XV245 is a set of 32-bit high speed bus switches 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 QS34XV245 is specially designed for direct interface betweeen 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 QS34XV245 an ideal device for
hot swapping applications.
The QS34XV245 is characterized for operation from-40
°
C to +85
°
C.
