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.

NOTES:
1. See Test Conditions under TEST CIRCUITS AND WAVEFORMS.
2. This parameter is guaranteed but not production tested.
3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone
is of the order of 0.2ns at C
L
= 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the
system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on
the driven side.
4. Minimums are guaranteed but not production tested.
