Description

The ST3DV520 is a 16-to-8 bit bidirectional multiplexer/demultiplexer low RON and high bandwidth switch suitable for analog video applications. The ST3DV520 supports high definition (HD) analog video switching standards and is also suitable for general purpose switching that requires high signal integrity. The device is designed for very low crosstalk, low bit-to-bit skew and low I/O capacitance. The signal from each input is multiplexed into one of two selected outputs while the unselected switch goes to HI-Z status. QFN56 Table 1. Device summary

  1. Measured by voltage drop between channels at indi cated current trough the switch. ON resistance is

determined by the lower of the voltage.

  1. Flatness is defined as the difference between the R ONMAX and RONMIN of ON resistance over the specified
  2. ΔRON measured at same VCC, temperature and voltage level.
