DESCRIPTION:
The QS3VH16244 HotSwitch is a 16-bit high band bus switch. The
QS3VH16244 has very low ON resistance, resulting in under 250ps propa-
gation delay through the switch. The switches can be turned ON under the
control of the LVTTL-compatible xG signal for bidirectional data flow with no
added delay or ground bounce. In the OFF and ON states, the switches are
5V-tolerant. In the OFF state, the switches offer very high impedance at the
terminals.
The combination of near-zero propagation delay, high OFF impedance, and
over-voltage tolerance makes the QS3VH16244 ideal for high performance
communications applications.
The QS3VH16244 is characterized for operation from -40°C to +85°C.
