QS4A110

10-Channel Analog Switch

The QS4A110 is a high-performance CMOS two-channel 5PST switch with 3-state outputs. The QS4A110, with 1.8GHz 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 QS4A110 operates at -40C to +85C.

Features

  • Low ON resistance: rDS(ON) = 5 ohm
  • Wide bandwidth: 1.8GHz (-3dB point)
  • Crosstalk: -100dB at 50KHz, -70dB at 5MHz, -50dB at 30MHz
  • Off-isolation: -70dB at 50KHz, -45dB at 5MHz, -40dB at 30MHz
  • Single 5V supply
  • Bidirectional
  • TTL-compatible control inputs
  • Ultra-low quiescent current: 3 uA
  • Switch turn on time of 6.5ns
  • Available in 24 pin QSOP package
