The LT1205 is a dual version that is configured as a 4-input, 2-output multiplexer. These multiplexers act as SPDT video switches with 10ns transition times at toggle rates up to 30MHz. The - 3d B bandwidth is 150MHz and 0.1d B gain flatness is 30MHz. Many parts can be tied together at their outputs by using the enable feature which reduces the power dissipation and raises the output impedance to 10MΩ. Output capacitance when disabled is only 3p F and the LT1203 peaks less than 3d B into a 50p F load. Channel crosstalk and disable isolation are greater than 90d B up to 10MHz. An on-chip buffer interfaces to fast TTL or CMOS logic. Switching transients are only 50m V with a 25ns duration. The LT1203 and LT1205 outputs are protected against shorts to ground. The LT1203/LT1205 are manufactured using Linear Technology’s proprietary plementary bipolar process. The LT1203 is available in both the 8-lead PDIP and SO package while the LT1205 is available in the 16-lead narrow body SO package.
