QS4A101

4-Channel Analog Switch

The QS4A101 is a high-performance CMOS analog four-channel SPST switch with individual enables. The QS4A101, with 1.4GHz 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 QS4A101 operates at -40C to +85C.

Features

  • Low ON resistance: rDS(ON) = 5 ohm
  • Wide bandwidth: 1.4GHz (-3dB point)
  • Crosstalk: -122dB at 50KHz, -80dB at 5MHz, -65dB at 30MHz
  • Off-isolation: -100dB at 50KHz, -75dB at 5MHz, -45dB at 30MHz
  • Single 5V supply
  • Bidirectional signal flow
  • TTL-compatible control inputs
  • Ultra-low quiescent current: 3 uA
  • Switch turn on time of 6.5ns
  • Available in 16 pin QSOP package
