ANALOG FOUR-CHANNEL

SPDT MUX/DEMUX

DESCRIPTION:

FEATURES:

The QS4A205 is a high-performance CMOS analog Four-Channel

SPDT multiplexer/demultiplexer with individual enables. The low On-

resistanceoftheQS4A205allowsinputstobeconnectedtooutputswithlow

insertion loss and high bandwidth. TTL-compatible control circuitry with

“Break-Before-Make” feature prevents contention.

• Low ON resistance: rDS(ON) = 5Ω

• Fast transition time: t^TRAN= 6ns

• Wide bandwidth: 830MHz (-3dB point)

• Crosstalk: -115dB at 50KHz, -100dB at 5MHz, -66dB at 30MHz

• Off-isolation: -90dB at 50KHz, -60dB at 5MHz, -50dB at 30MHz

• Single 5V supply

• Can be used as multiplexer or demultiplexer

• TTL-compatible control inputs

The QS4A205 with 830MHz bandwidth makes it ideal for high-perfor-

mancevideosignalswitching,audiosignalswitching,andtelecommrouting

applications. High performance and low power dissipation makes this

deviceidealforbatteryoperatedandremoteinstrumentationapplications.

The QS4A205 is offered in the QSOP package and has several advan-

tages over conventional packages such as PDIP and SOIC including:

• Reducedsignaldelaysduetodensercomponentpackagingoncircuit

boards

• Ultra-low quiescent current: 3μA

• Available in QSOP package

APPLICATIONS:

• High-speed video signal switching/routing

• HDTV-quality video signal routing

• Audio signal switching/routing

• Data acquisition

• Reduced system noise due to less pin inductance resulting in lower

ground bounce

The QS4A205 is characterized for operation at -40°C to +85°C.

• ATE systems

• Telecomm routing

• Switch between multiple video sources

• Token Ring transceivers

• High-speed networking
