LT1203/LT1205
Note 2:
The digital inputs (pins 5, 6 for the LT1203, pins 9, 10, 13, 14 for to pin 1 and measure the time for disappearance of 0.5V at pin 7 when the LT1205) are protected against ESD and overvoltage with internal pin 5 goes from 0V to 5V. Apply 1VDC to pin 3 and measure the time for SCRs. For inputs ≤±6V the SCR will not fire. Voltages above 6V will fire the appearance of 0.5V at pin 7 when pin 5 goes from 0V to 5V. Apply the SCR and the DC current should be limited to 50mA. To turn off the 1VDC to pin 3 and measure the time for disappearance of 0.5V at pin 7 SCR the pin voltage must be reduced to less than 2V or the current when pin 5 goes from 5V to 0V. For the LT1205 the same test is reduced to less than 10mA. performed on both MUXs.

Commercial grade parts are designed to operate over the = 0V. Apply 1VDC to pin 1 and measure the time for disappearance of 0.2V temperature range of – 40°C to 85°C but are neither tested nor guaranteed at pin 7 when pin 6 goes from 5V to 0V. Pin 5 voltage = 0V. Apply 1VDC beyond 0°C to 70°C. Industrial grade parts specified and tested over to pin 3 and measure the time for the appearance of 0.5V at pin 7 when – 40°C to 85°C are available on special request, consult factory. pin 6 goes from 0V to 5V. Pin 5 voltage = 5V. Apply 1VDC to pin 3 and

For the LT1205 the same test is performed D according to the following formulas: on both MUXs. LT1203CN8: TJ = TA + (PD × 100°C/W)

V LT1203CS8: T IN = 0dBm (0.223VRMS) at 10MHz on one input with the other J = TA + (PD × 150°C/ W) input selected and RS = 10Ω. For disable crosstalk all inputs are driven LT1205CS: TJ = TA + (PD × 100°C/W) simultaneously. In disable the output impedance is very high and signal
Note 6:
Slew rate is measured at ±2.0V on a ±2.5V output signal while couples across the package; the load impedance determines the crosstalk. operating on ±15V supplies, RL = 1k.
