Description
The QS4A210 is a high-performance CMOS two-channel SP4T multiplexer/demultiplexerwith individual enables. The low On-resistance of theQS4A210 allows inputs to be connected to outputs with low insertion loss andhigh bandwidth. TTL-compatible control circuitry with “Break-Before-Make”feature prevents contention. The QS4A210 with 700MHz bandwidth makes it ideal for high-performancevideo signal switching, audio signal switching, and telecom routingapplications. Low power dissipation makes this device ideal for batteryoperated and remote instrumentation applications. The QS4A210 is offered in the QSOP package which has severaladvantages over conventional packages such as PDIP and SOIC, including:• Reduced signal delays due to denser component packaging on circuitboards• Reduced system noise due to less pin inductance, resulting in lowerground bounce The QS4A210 is characterized for operation at -40°C to +85°C.
