2.5V / 3.3V DUAL 4:1 MUX/DEMUX

HIGH BANDWIDTH BUS SWITCH

FEATURES:

DESCRIPTION:

• N channel FET switches with no parasitic diode to VCC

– Isolation under power-off conditions

– No DC path to VCC or GND

The QS3VH253 HotSwitch Dual 4:1 multiplexer/demultiplexer is a high

bandwidth bus switch. The QS3VH253 has very low ON resistance,

resulting in under 250ps propagation delay through the switch. The Select

(Sx) inputs control the data flow. The multiplexers/demultiplexers are

enabled when the Enable (EA, EB) inputs are low. In the ON state, the

switchescanpasssignalsupto5V. IntheOFFstate,theswitchesoffervery

high impedance at the terminals.

– 5V tolerant in OFF and ON state

• 5V tolerant I/Os

• Low RON - 4Ω typical

• Flat R^ONcharacteristics over operating range

• Rail-to-rail switching 0 - 5V

The combination of near-zero propagation delay, high OFF impedance,

and over-voltage tolerance makes the QS3VH253 ideal for high perfor-

mance communication applications.

• Bidirectional dataflow with near-zero delay: no added ground

bounce

• Excellent R^ONmatching between channels

• VCC operation: 2.3V to 3.6V

The QS3VH253 is characterized for operation from -40°C to +85°C.

• High bandwidth - up to 500MHz

• LVTTL-compatible control Inputs

• Undershoot Clamp Diodes on all switch and control Inputs

• Low I/O 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
