PRODUCT DESCRIPTION
The AD8184 is a high speed 4-to-1 multiplexer. It offers –3 dB
signal bandwidth of 700 MHz along with a slew rate of 750 V/ s.
With 95 dB of crosstalk and 115 dB isolation, it is useful in
many high speed applications. The differential gain and differ-
ential phase error of 0.01% and 0.01 , along with 0.1 dB flatness
of 75 MHz, make AD8184 ideal for professional video multi-
plexing. It offers 10 ns switching time, making it an excellent
choice for pixel switching (picture-in-picture) while consuming
less than 4.5 mA on 5 V supply voltage.
The AD8184 offers a high speed disable feature allowing the
output to be put into a high impedance state. This allows mul-
tiple outputs to be connected together for cascading stages while
the “OFF” channels do not load the output bus. It operates on
voltage supplies of 5 V and is offered in 14-lead PDIP and
SOIC packages.
