Absolute Maximum Rating Indicates limit beyond which damage to the device may occur. 2. Operating Ratings indicate conditions for which the device is functional but do not guarantee specific performance limits. For guaranteed specifications and test conditions, See the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. 3. VCC supply pin22 must be externally wired to gether to prevent internal damage during VCC power on/off cycles. 10 KA2507 WIDE BAND ANALOG SWITCH FOR MONITORS TEST CIRCUIT 0.01uF VCC = 5 V 47uF 0.01uF R1 1 24 2 23 3 22 4 21 5 20 SW 50 4.7uF 0.01uF G1 ROUT 0.01uF 50 4.7uF 0.01uF B1 47uF SOG 1uF 50 4.7uF 6 H1 V1 GOUT 0.01uF R2 S1D2507B 19 CSYNC 470K 7 18 8 17 9 16 HOUT 10 15 VOUT 11 14 V2 12 13 H2 47uF BOUT 50 4.7uF 0.01uF G2 50 4.7uF 0.01uF B2 50 4.7uF TEST METHODS Oscilloscope S1D2507B01 R/G/B/H/V 50Ω 50§Ù 50 Output TEST POSITION 11 WIDE BAND ANALOG SWITCH FOR MONITORS KA2507 TEST SIGNAL FORMAT Table 9.
