HIGH, HIGH BANDWIDTH SWITCH

DESCRIPTION:

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

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.

ance, and over-voltage tolerance makes the QS3VH126 ideal for high

performance communications applications.

The QS3VH126 is a high bandwidth bus switch. The QS3VH126 has

The combination of near-zero propagation delay, high OFF imped-

The QS3VH126 is characterized for operation from -40°C to +85°C.
