LT1205 150MHz Video Multiplexers

The LT1203 is a wideband 2-input video multiplexer designed for pixel switching and broadcast quality routing. 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 – 3dB bandwidth is 150MHz and 0.1dB 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 10M Ohm. Output capacitance when disabled is only 3pF and the LT1203 peaks less than 3dB into a 50pF load. Channel crosstalk and disable isolation are greater than 90dB up to 10MHz. An on-chip buffer interfaces to fast TTL or CMOS logic. Switching transients are only 50mV 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 complementary 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
