APPLICATIONS:
• High-speed video signal switching/routing
• HDTV-quality video signal multiplexing
• Audio signal switching/routing
• Data acquisition
• ATE systems
• Telecomm routing
• Switch between multiple video sources
• Token Ring transceivers
• High-speed networking
DESCRIPTION:
The QS4A215 is a high-performance CMOS six-channel multiplexer/
demultiplexer with individual enables. The low ON-resistance of the QS4A215
allows inputs to be connected to outputs with low insertion loss and high
bandwidth. TTL-compatible control circuitry with “Break-Before-Make”
feature prevents contention.
The QS4A215 with 700MHz bandwidth makes it ideal for high-perfor-
mance video signal switching, audio signal switching, and telecom routing
applications. High performance and low power dissipation makes this
device ideal for battery operated and remote instrumentation applications.
The QS4A215 is offered in the QVSOP 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 QS4A215 is characterized for operation at -40°C to +85°C.
