HIGH BANDWIDTH BUS SWITCH
IDTQS3VH251
FEATURES:
• N channel FET switches with no parasitic diode to VCC
– Isolation under power-off conditions
– No DC path to VCC or GND
– 5V tolerant in OFF and ON state
• 5V tolerant I/Os
• Low RON - 4Ω typical
• Flat RON characteristics over operating range
• Rail-to-rail switching 0 - 5V
• Bidirectional dataflow with near-zero delay: no added ground
bounce
• Excellent RON matching between channels
• VCC operation: 2.3V to 3.6V
• High bandwidth - up to 500MHz
• LVTTL-compatible control Inputs
• Undershoot Clamp Diodes on all switch and control Inputs
• Low Demux capacitance, 4pF typical
• Available in QSOP and TSSOP packages
APPLICATIONS:
• Hot-swapping
• Multiplexing/demultiplexing
• Low distortion analog switch
• Replaces mechanical relay
• ATM 25/155 switching

DESCRIPTION:
The QS3VH251 HotSwitch Quad 2:1 multiplexer/demultiplexer is a high
bandwidth bus switch. The QS3VH251 has very low ON resistance,
resulting in under 250ps propagation delay through the switch. The Select
(Sx) 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 QS3VH251 ideal for high perfor-
mance comminucation applications.
The QS3VH251 is characterized for operation from -40°C to +85°C.
