HIGH-PERFORMANCE CMOS

SIX CHANNEL SP4T MUX/DEMUX

FEATURES:

DESCRIPTION:

• Low ON resistance: rDS(ON) = 5Ω

The QS4A215 is a high-performance CMOS six-channel multiplexer/

demultiplexerwithindividualenables.ThelowON-resistanceoftheQS4A215

allows inputs to be connected to outputs with low insertion loss and high

bandwidth. TTL-compatible control circuitry with “Break-Before-Make”

featurepreventscontention.

• Fast transition time: t^TRAN= 6ns

• Wide bandwidth: 700MHz (-3dB point)

• Crosstalk: -110dB at 50KHz, -68dB 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 QS4A215 with 700MHz bandwidth makes it ideal for high-perfor-

mancevideosignalswitching, audiosignalswitching, andtelecomrouting

applications. High performance and low power dissipation makes this

deviceidealforbatteryoperatedandremoteinstrumentationapplications.

The QS4A215 is offered in the QVSOP package which has several

advantages over conventional packages such as PDIP and SOIC, includ-

ing:

• Reducedsignaldelaysduetodensercomponentpackagingoncircuit

boards

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

ground bounce

• Ultra-low quiescent current: 9μA

• Available in QSOP package

APPLICATIONS:

• High-speed video signal switching/routing

• HDTV-quality video signal multiplexing

• Audio signal switching/routing

• Data acquisition

• ATE systems

The QS4A215 is characterized for operation at -40°C to +85°C.

• Telecomm routing

• Switch between multiple video sources

• Token Ring transceivers

• High-speed networking

NOTES:

1. Typical values are at VCC = 5.0V, TA = 25°C.

2. Max value is guaranteed but not production tested.

3. Measured by voltage drop between A and C pins or B and D pins at indicated current through the switch. ON resistance is determined by the lower of the voltages on the

two (I, Y) pins.

4. The bus switch contributes no group delay other than the RC delay of the ON resistance of the switch and load capacitance. Group 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.
