ISL59420

400MHz Multiplexing Amplifier

OVERVIEW

The ISL59420 is a 420MHz bandwidth 2:1 multiplexing amplifier designed primarily for video switching. This Mux-amp has user-settable gain and also feature a high speed three-state function to enable the output of multiple devices to be wired together. All logic inputs have pull-downs to ground and may be left floating. The ENABLE pin, when pulled high, sets the ISL59420 to the low current power-down mode for power sensitive applications - consuming just 5mW.

KEY FEATURES

  • 420MHz (-3dB) Bandwidth (AV = 1, VOUT = 400mVP-P)
  • 165MHz (-3dB) Bandwidth (AV = 2, VOUT = 2VP-P)
  • Slew Rate (AV = 1, RL = 500Ω, VOUT = 4V): 966V/µs
  • Slew Rate (AV = 2, RL = 500Ω, VOUT = 5V): 1462V/µs
  • Selectable Gain
  • High Speed Three-State Output (HIZ)
  • Low Current Power-Down: 5mW
  • Pb-Free (RoHS Compliant)
