IDTQS4A105 HIGH-PERFORMANCE CMOS TWO-CHANNEL 4PST SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-PERFORMANCE CMOS TWO CHANNEL 4PST SWITCH IDTQS4A105 FEATURES: DESCRIPTION: • • • • The QS4A105 is a high-performance CMOS two-channel 4PST switch with 3-state outputs. The low ON resistance of the QS4A105 allows inputs to be connected to outputs with low insertion loss and high bandwidth. The QS4A105, with 1.3GHz bandwidth, is ideal for high-performance video signal switching, audio signal switching, and telecomm routing applications. Low power dissipation makes this device ideal for battery operated and remote instrumentation applications. The QS4A105 is offered in the QSOP 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 Ω Low ON resistance: rDS(ON) = 5Ω Wide bandwidth: 1.3GHz (-3dB point) Crosstalk: 100dB at 50KHz, -70dB at 5MHz, -50dB at 30MHz Off-isolation: -90dB at 50KHz, -60dB at 5MHz, -55dB at 30MHz Single 5V supply Bidirectional signal flow TTL-compatible control inputs µA Ultra-low quiescent current: 3µ Switch turn on time of 6.5ns Available in QSOP package • • • • • • APPLICATIONS: • • • • • • • • High-speed video signal switching/routing HDTV-quality video signal routing Audio signal switching/routing Data acquisition ATE systems Telecomm routing Token Ring transceivers High-speed networking The QS4A105 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 (A, C, or B, D) 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.
