FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH125 is a high bandwidth, Quad bus switch. The QS3VH125
has very low ON resistance, resulting in under 250ps propagation delay
through the switch. The switches can be turned ON under the control
of individual LVTTL-compatible active low Output Enable signals for
bidirectional data flow with no added delay or ground bounce. In the ON
state, the switches can pass signals up to 5V. In the OFF state, the
switches offer very high impedence at the terminals.
The combination of near-zero propagation delay, high OFF imped-
ance, and over-voltage tolerance makes the QS3VH125 ideal for high
performance communications applications.
The QS3VH125 is characterized for operation from -40°C to +85°C.
