2.5V/3.3V QUAD 2:1 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 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.

– 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 QS3VH257 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 QS3VH257 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, SOIC, and TSSOP packages

APPLICATIONS:

• Hot-swapping

• Multiplexing/demultiplexing

• Low distortion analog switch

• Replaces mechanical relay

• ATM 25/155 switching
