IDTQS3VH2862
PRELIMINARY
DESCRIPTION:
The QS3VH2862 HotSwitch is a high bandwidth bus switch with 10-bit
active high and low enable. The QS3VH2862, with 25Ω ON resistance and
1.35ns propagation delay, is ideal for line matching and low noise
environments. The switches are controlled by independent active low
enable (BE) and active high enable (BE) control. 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 small propagation delay, high OFF impedance, and
over-voltage tolerance makes the QS3VH2862 ideal for high performance
communication applications.
The QS3VH2862 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 1.35ns 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.
