WIDE BAND ANALOG SWITCH

note17, note18) The condition is as table 1. Set SW15 to GND (OPEN), SG7 is as the input signal of

input terminal, measure the waveform of output. Rising delay time is as Trd1 (Trd2).

Falling delay time is as Tfd1(Tfd2). Reference to the Fig. as shown below.

note19) 1. The condition is as table 1. SG1 is as the input signal of Pin1, Pin3, Pin5, and SG7 is as the

input signal of Pin6, Pin7. There is no input at another pins.

2. Input 0V at Pin15, confirm that there are signals output from T.P.29, T.P.26, T.P.23, T.P.21,

T.P.18,T.P.17.

3. Increasing gradually the voltage of terminal Pin15. Read the voltage when there is no signal

output from the terminals listed as above. The voltage is as Vsth1.

4. SG1 as the input signal of Pin8, Pin10, Pin12, and SG7 as the input signal of Pin13, Pin14.

There is no input at another pins.

5. Inputs 5V at Pin15, confirm that there is no signal output from T.P29, T.P.26, T.P.23, T.P.21,

T.P.18,T.P.17.

6. Decreasing gradually the voltage of terminal Pin 15. Read the voltage when there are signals

output from the terminals listed as above. The voltage is as Vsth2.

note20) The condition is as table 1. SG8 of luminance 0% is the input signal of Pin20. Increase sync level

from 0Vp-p to 0.02Vp-p. Confirm outputting no pluse.

note21) The condition is as table 1. SG8 of luminance 100%(or 0%) is the input signal of Pin20. Decrease

sync level from 0.3Vp-p to 0.2Vp-p. Confirm no malfunction produced by noise.

note22) The condition is as table 1. SG8 of luminance 100%(or 0%) is the input signal of Pin20. Measure

the high(low) at SyncOUT. The measured value is treated as VSH(VSL).

note23) The condition is as table 1. SG8 of luminance 100%(or 0%) is the input signal of Pin20. SyncOUT

becomes High with sync part of SG8. Measure the time needed for the front(rear) edge of SG8

sync to fall(rise) from 50% and for SyncOUT to rise(fall) from 50% with an active prove. The

measured value is treated as Tdsf(Tdsr).
