ESCRIPTIO
The LT1203 is a wideband 2-input video multiplexer
designed for pixel switching and broadcast quality rout-
ing. 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
. Output capaci-
tance 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.
