IDTQS4A210

DESCRIPTION:

The QS4A210 is a high-performance CMOS two-channel SP4T multi-

plexer/demultiplexer with individual enables. The low On-resistance of the

QS4A210allowsinputstobeconnectedtooutputswithlowinsertionlossand

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

feature prevents contention.

The QS4A210 with 700MHz bandwidth makes it ideal for high-perfor-

mance video signal switching, audio signal switching, and telecom routing

applications. Low power dissipation makes this device ideal for battery

operated and remote instrumentation applications.

The QS4A210 is offered in the QSOP package which has several

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

ing:

• Reduced signal delays due to denser component packaging on circuit

boards

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

ground bounce

The QS4A210 is characterized for operation at -40°C to +85°C.
