AD8187:  480 MHz, Single Supply, Triple 2:1, Buffered (G= +2) Multiplexer

Product Description

The AD8187 (G = +2) is a high-speed single supply Triple 2-to-1 multiplexer. It offers -3 dB large signal band-width of over 480 MHz along with a slew rate in excess of 1500 V/µs. With better than -78 dB of all hostile crosstalk and 95 dB isolation, it is useful in many high speed applications. The differential gain and differential phase error of 0.05% and 0.05°, along with 0.1 dB flatness to 85 MHz makes the AD8187 ideal for professional and component video multiplexing. It offers a 4 ns switching time, making it an excellent choice for switching video signals, while consuming less than 20 mA on +5 V supply voltage (100 mW).

The AD8187 has a high speed disable feature that sets the outputs into a high impedance state. This allows the building of larger input arrays while minimizing "OFF" channel output loading. The devices are offered in 24 lead TSSOP package.
