Note 6) Trigger sensitivity (A), Trigger current (A) < TRIG-A, (I-TRIG-A)>

S1 A, S2 ON, S3 V (SW position)

Turn VOL gradually to increase the indication of VM from OV. In this case, pin and pin

of the muting output terminal are at

L level (about OV when output transistor is ON.). As the value of VM is increased, pin and pin are turned from L level to

H level at a certain point (about 3.5mA when output transistor is OFF. In this case, if the value of VM is VML(A) the negative

trigger sensitivity (A) is given by the following equation:

Negative trigger sensitivity (A), -TRIG-A=V1-VMH(A) If, after obtaining of the negative trigger sensitivity, the

value of VM is further increased, pin and pin are returned from H level to L level.

In this case, if the indicating value of VM is VMH(A), the positive trigger sensitivities (A) is given as follows:

+TRIG-A=VMH(A)-V1

To measure the trigger current (I-TRIG-A),read the current of pin at the measuring time of the VML(A) and VMH(A)

described above.

Note 7) Trigger sensitivity (B), trigger current (B) < TRIG-B, (I-TRIG-B)>

S1 B, S2 ON, S3 V (SW positions)

Measuring method is the same as mentioned in Note 5.

Negative trigger sensitivity, -TRIG-B=V3-VML(B)

Positive trigger sensitivity, -TRIG-B=VMH(B)-V3

Note 8) Detection sensitivity and current at power OFF (V4 OFF, I4 OFF)

S1 C, S2 OFF, S3 V (SW positions)

Turn VOL gradually to increase the indicating value of VM from OV. When pin and pin of the muting output are turned

form L level to H level, the value of VM comes to V4. In this case, the current of pin is I4 OFF.

Note 9) Saturation Voltage and maximum sink current at muting ON (VCE(sat), ICMAX)

S1 A or B, S2 ON, S3 V (SW positions)

Measure the voltage and current of pin and pin

when indicating value of VM is set to OV. (Set Rg=0 at measuring the current)

Note 10) Muting attenuation and muting time at power ON (ATT, MT) In the measuring circuit 2, the time from the instant when

S1 is ON (While S2 remains OFF) and VCC is applied to the circuit, to the moment when pin and pin are turned from L level

to H level is taken as the muting time MT.

Measure the AC voltage at pin or pin with S1 remains ON.

In addition, term S2 ON, and measure the AC voltage at pin or pin .

Muting attenuation

AC voltage at pin

ATT = 20log (

( ) at S2 OFF )
