FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH126 is a high bandwidth bus switch. The QS3VH126 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 high Output Enable signals for bidirec-
tional 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 impedance,
and over-voltage tolerance makes the QS3VH126 ideal for high perfor-
mance communications applications.
The QS3VH126 is characterized for operation from -40°C to +85°C.
