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-performance 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, including: • Reduced signal delays due to denser component packaging on circuit boards • Reduced system noise due to less pin inductance, resulting in lower ground bounce APPLICATIONS: • • • • • • • • • IDTQS4A215 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 The QS4A215 is characterized for operation at -40°C to +85°C.

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.
