PRODUCT DESCRIPTION
Table I. Truth Table
The AD8074/AD8075 are high-speed triple video buffers with
G = +1 and +2 respectively. They have a 鈥? dB full signal band-
width in excess of 450 MHz, along with slew rates in excess of
1400 V/碌s. With better than 鈥?0 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掳. 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
卤
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 鈥淥FF鈥?chan-
nel output loading. The AD8074/AD8075 are offered in a
16-lead TSSOP package.
