500 MHz, G=+1 and +2 Triple Video Buffers with Disable

The AD8074 /AD8075 are high-speed triple video buffers with a G = +1 and +2 respectively. They operate on ±5V and have a -3dB full signal bandwidth in excess of 500MHz, along with slew rates in excess of 1350V/µs. With better than -80dB of all hostile crosstalk and 90dB isolation, they are useful in many high-speed applications. The differential gain and differential phase error are 0.01% and 0.01°. Gain Flatness of 0.1dB up to 70MHz make the AD8074/75 ideal for RGB buffering or driving. They consume less than 30mA on a ±5V supply voltage.

Both devices offer a high-speed disable feature that allows the outputs to be put into a high impedance state. This allows the building of larger input arrays while minimizing "OFF" channel output loading. The AD8074/75 are offered in a 16 lead TSSOP package.
