IDTQS4A105 HIGH-PERFORMANCE CMOS TWO-CHANNEL 4PST SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS4A105 HIGH-PERFORMANCE CMOS TWO CHANNEL 4PST SWITCH FEATURES: DESCRIPTION: Low ON resistance: rDS(ON) = 5 The QS4A105 is a high-performance CMOS two-channel 4PST switch Wide bandwidth: 1.3GHz (-3dB point) with 3-state outputs. The low ON resistance of the QS4A105 allows inputs Crosstalk: 100dB at 50KHz, -70dB at 5MHz, -50dB at 30MHz to be connected to outputs with low insertion loss and high bandwidth. Off-isolation: -90dB at 50KHz, -60dB at 5MHz, -55dB at The QS4A105, with 1.3GHz bandwidth, is ideal for high-performance 30MHz video signal switching, audio signal switching, and telecomm routing Single 5V supply applications. Low power dissipation makes this device ideal for battery Bidirectional signal flow operated and remote instrumentation applications. TTL-compatible control inputs The QS4A105 is offered in the QSOP package which has several Ultra-low quiescent current: 3A advantages over conventional packages such as PDIP and SOIC, includ- Switch turn on time of 6.5ns ing: Available in QSOP package Reduced signal delays due to denser component packaging on circuit boards Reduced system noise due to less pin inductance APPLICATIONS: High-speed video signal switching/routing The QS4A105 is characterized for operation at -40C to +85C. HDTV-quality video signal routing Audio signal switching/routing Data acquisition ATE systems Telecomm routing Token Ring transceivers High-speed networking FUNCTIONAL BLOCK DIAGRAM A1 C1 A2 C2 A3 C3 A4 C4 B1 D1 B2 D2 B3 D3 B4 D4 E1 CONTROL LOGIC E2 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
