... 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. V RED ...

... Differential Phase (Note 11) Insertion Loss The denotes specifications which apply over the specified temperature range. Note 1: The analog inputs (pins 1, 3 for the LT1203, pins for the LT1205) are protected against ESD and overvoltage with internal SCRs. CONDITIONS V = 15V, V ...

... LT1203/LT1205 Note 2: The digital inputs (pins 5, 6 for the LT1203, pins 9, 10, 13, 14 for the LT1205) are protected against ESD and overvoltage with internal SCRs. For inputs 6V the SCR will not fire. Voltages above 6V will fire the SCR and the DC current should be limited to 50mA. To turn off the SCR the pin voltage must be reduced to less than 2V or the current reduced to less than 10mA ...

... It is not necessary to use equal value supplies however, the output offset voltage will change. The offset will change about 300 V per volt of supply mismatch. The LT1203/LT1205 have a very wide bandwidth yet are tolerant of power supply bypassing. The power supplies should be by- passed with a 0 ...

... The slight rise time degradation at the RGB MUX output is due to the bandwidth of the LT1260 current feedback amplifier used to drive the 75 cable. In Figure 2b, the LT1203 switches to an input at zero at the end of the first pixel and removes the following pixels. LT1203/05 • AI03 ...

... U LT1203/05 • F02a Figure 4. RGB MUX Frequency Response of Demonstration Board #041 Input Expansion The output impedance of the LT1203/LT1205 is typically 20 when enabled and 10M selected. This high disabled output impedance allows the output of many LT1205s to be shorted together to form large crosspoint arrays. With their outputs shorted to- gether, shoot-through current is low because the “ ...
