2.5V/3.3V QUAD 2:1 MUX/DEMUX
HIGH BANDWIDTH BUS SWITCH
FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH257 HotSwitch Quad 2:1 multiplexer/demultiplexer is a high
bandwidth bus switch. The QS3VH257 has very low ON resistance,
resulting in under 250ps propagation delay through the switch. The Select
(S) input controls the data flow. The multiplexers/demultiplexers are
enabled when the Enable (E) input is low. 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 QS3VH257 ideal for high perfor-
mance communication applications.
The QS3VH257 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 CL = 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.
5. Maximum toggle frequency for S or E control input (pass voltage > VCC, VIN = 5V, RLOAD ≥ 1MΩ, no CLOAD).
