| NJM2596 5-INPUT 3-OUTPUT VIDEO SWITCH FOR S2 sGENERAL DESCRIPTION The NJM2596 is a 5-input 3-output video switch for S2. Its switches select one from five signals received from TV, VTR, DVD, TV GAME and others. The NJM2596 is designed for audio visual items, such as AV amplifier and others, because it includes DC interface for S2. sFEATURES qOperating Voltage 4.0 to 6.5V qOperating Current 16mA typ. at Vcc=5V qInternal DC Interface For S2 qInternal 6dB Amplifier qInternal 75ohm Driver qBipolar Technology qPackage Outline DMP24 sBLOCK DIAGRAM Vcc 18 Vin1 14 Vin2 16 Vin3 19 Vin4 1 SW 3 6dB Am p. 75 Driv er sPACKAGE OUTLINE NJM2596M SW 2 9 SW 1 SW 1 15 SW 5 21 SW 5 SW 2 6dB Am p. 75 Driv er 10 Vout1 SW 4 SW 1 6dB Am p. 75 Driv er 8 Vout2 Vin5 22 SW 2 5 Vout3 SDCin1 13 SDCin2 17 SDCin3 20 SDCin4 2 SW 3 SW 1 C OM P SW 2 11 SDCout1 SW 4 7 SDCout2 SDCin5 23 4 24 SW 3 3 SW 4 12 G ND 6 V EE SDCout3 Ver.1 -1- NJM2596 sABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL Vcc PD Topr Tstg RATINGS 7.0 500 -40 to +85 -40 to +125 (Ta=25C) UNIT V mW C C sELECTRICAL CHARACTERISTICS(Video System ,V+/V-=5V, RL=150ohm ,Ta=25C) PARAMETER [ Video System ] Positive Operating Current Negative Operating Current Voltage Gain Frequency Characteristics Total Harmonic Distortion Offset Output DC Voltage Between Input Crosstalk Mute Crosstalk Input Impedance [ SDC System ] Aspect Ratio Output DC Voltage 1 Aspect Ratio Output DC Voltage 2 Aspect Ratio Output DC Voltage 3 Output Resistance [ Control System ] Switch Change High Voltage Switch Change Low Voltage VcH VcL 2.0 0.0 V+ 0.8 V V VSout1 VSout2 VSout3 RSDC SDCin=0 to 0.5V SDCin=1.3 to 2.5V SDCin=3.4 to V At Mute output + SYMBOL Icc Iee Gv Gf THD Vos CT CTm Rin TEST CONDITION No signal, at SDCout=0V No signal, at SDCout=0V Vin=0.5Vpp, f=100kHz Vin=0.5Vpp, f=5MHz/100kHz Vin=0.5Vpp, f=15kHz No signal Vin=0.5Vpp, f=4.43MHz Vin=0.5Vpp, f=4.43MHz MIN. 6.0 -1.0 0.0 -40 -0.1 2.0 3.5 160 TYP. 16.0 -16.0 6.3 0.0 0.1 0.0 -65 -55 20 0.0 2.2 200 MAX. +29.0 -29.0 6.8 +1.0 1.0 +40 0.1 2.4 240 UNIT mA mA dB dB % mV dB dB k V V V k Ver.1 -2- NJM2596 sControl Signal - Output Signal (L=VCL,H=VCH, X=L or H) SW1 L H H SW2 H L H L H SW3 X X X SW4 X L L SW5 H H L H L H L H L H L H L H L L Vout1/SDCout1 Vin1/SDCin1 Vin1/SDCin1 OFF Vin2/SDCin2 OFF Vin3/SDCin3 OFF Vin4/SDCin4 OFF Vin4/SDCin4 OFF Vin5/SDCin5 OFF Vin5/SDCin5 OFF OFF Vout2/SDCout2 OFF OFF OFF Vin2/SDCin2 Vin2/SDCin2 Vin3/SDCin3 Vin3/SDCin3 Vin4/SDCin4 Vin4/SDCin4 Vin4/SDCin4 Vin4/SDCin4 Vin5/SDCin5 Vin5/SDCin5 Vin5/SDCin5 Vin5/SDCin5 OFF Vout3/SDCout2 Vin1/SDCin1 OFF Vin1/SDCin1 OFF OFF Vin3/SDCin3 Vin3/SDCin3 Vin4/SDCin4 Vin4/SDCin4 OFF OFF Vin5/SDCin5 Vin5/SDCin5 OFF OFF OFF H H H L H L L H H H H H L L L L X X * Information of [OFF] AC System : MUTE DC System: Connect to GND with High impedance Ver.1 -3- NJM2596 sTEST CIRCUIT 75 0.1uF 1 10pF 2 100pF 3 10k 4 22uF + 75 + 75 100uF 6 0.1uF 10k + 8 75 75 22uF 9 100pF + 75 75 22uF 11 10k 12 GND SDCin1 13 SDCout1 Vin1 14 10pF 10 Vout1 SW1 15 75 0.1uF SW2 Vin2 16 100pF Vout2 SDCin2 17 75 0.1uF 7 SDCout2 VCC 18 + VEE Vin3 19 0.1uF 100uF 10pF SDCout3 SW5 21 10pF 5 Vout3 SDCin3 20 0.1uF 75 SW4 Vin5 22 100pF SDCin4 SDCin5 23 75 0.1uF Vin4 SW3 24 10pF 100pF Ver.1 -4- NJM2596 sAPPLICATION CIRCUIT 75 1uF 0.1uF 1 Vin4 SW3 24 1uF 2 SDCin4 SDCin5 23 0.1uF 75 3 10k 4 75 0.1uF 5 100uF 0.1uF 6 SW4 Vin5 22 SDCout3 SW5 21 1uF Vout3 SDCin3 20 0.1uF 75 VEE Vin3 19 0.1uF 100uF 7 10k 75 8 0.1uF 9 SDCout2 VCC 18 1uF Vout2 SDCin2 17 0.1uF 75 SW2 Vin2 16 10 Vout1 75 0.1uF 11 SDCout1 10k 12 GND SW1 15 Vin1 14 0.1uF 75 SDCin1 13 1uF Ver.1 -5- NJM2596 sEQUIVALENT CIRCUIT PIN NO.
