PRODUCT DESCRIPTION
The AD8074/AD8075 are high-speed triple video buffers with
G = +1 and +2 respectively. They have a –3 dB full signal band-
width in excess of 450 MHz, along with slew rates in excess of
1400 V/µs. With better than –80 dB of all hostile crosstalk and
90 dB isolation, they are useful in many high-speed applica-
tions. The differential gain and differential phase error are 0.01%
and 0.01°. Gain flatness of 0.1 dB up to 50 MHz makes the
AD8074/AD8075 ideal for RGB buffering or driving. They
consume less than 30 mA on a ± 5 V supply.
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” chan-
nel output loading. The AD8074/AD8075 are offered in a
16-lead TSSOP package.
