Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 617/329-4700 World Wide Web Site: http://www.analog.com Fax: 617/326-8703 © Analog Devices, Inc., 1997 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/ µs. 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. *All trademarks are the property of their respective holders. Table I.
