Truth Table PRODUCT DESCRIPTION The AD8074/AD8075 are high-speed triple video buffers with OE OUT0, 1, 2 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 0 IN0, IN1, IN2 1400 V/ s. With better than 80 dB of all hostile crosstalk and 1 High Z 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. Rev.
