BA7626F

TECHNICAL NOTE High performance video signal switcher Five inputs Dual Circuits Video Signal Switchers BA7626F/FS ●Description The BA7626F/FS is a 5-input video signal switching circuit with a broadband 6 dB amplifier that was developed for AV amplifier input switching. Just by devising a transistor buffer in the output, player switching of two VCR or other videotape players and three DVD players or other playback devices is possible. Moreover, input switching and switching of recording to a VCR or other device also can be performed independently. Since the input circuit of the BA7626F/FS is terminated by 20kΩ impedance, it is suited to not only video signal but also chroma signal or audio signal switching. ●Features 1) 5 input line, 3 output line switching 2) Built-in 6 dB amplifier 3) 5V operating voltage 4) 20kΩ input impedance ●Use AV amplifiers, Video selectors, etc. ●Lineup Part No. Package Input type BA7626F BA7626FS SOP16 SSOP-A16 Bias (R=20kΩ) ●Absolute Maximum Ratings(Ta=25℃) Parameter Supply voltage Power dissipation BA7626F BA7626FS Symbol Vcc Pd Topr Limits 9 300 ※1 600 ※2 -25～+70 Unit V mW ℃ Operating temperature Storage temperature Tstg -55～+125 ℃ ※1 Deratings is done at 3.0mW/℃ above Ta=25℃.（BA7626F） ※2 Deratings is done at 6.0mW/℃ above Ta=25℃.（BA7626FS） ●Operating Range(Ta=25℃) Parameter Power supply voltage Symbol Vcc Min 4.5 Typ 5.0 Max 5.5 Unit V Aug.2008 ●Electrical characteristics (Unless otherwise noted Ta=25℃, Vcc=5.0V) Parameter Symbol Min.

When modifying externally attached component constants before use, determine them so that they have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only for static characteristics but also including transient characteristics. 3) Absolute maximum ratings If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may be damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you think of a case in which absolute maximum ratings are exceeded, enforce fuses or other physical safety measures and investigate how not to apply the conditions under which absolute maximum ratings are exceeded to the LSI. 4) GND potential Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the voltage of each pin does not become a lower voltage than the GND pin, including transient phenomena. 5) Thermal design Perform thermal design in which there are adequate margins by taking into account the allowable power dissipation in actual states of use. 6) Shorts between pins and misinstallation When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by a foreign substance coming between pins of the LSI or between a pin and a power supply or a pin and a GND. 7) Operation in strong magnetic fields Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction. 2/4 ●Pin descriptions（Ta=25℃, VCC=5V） Equivalent circuit BA7626F/FS IN VCC Pin No. Pin name 3 5 7 12 16 IN5 IN4 IN3 IN2 IN1 QN 200 QN 20k QN 4.3V 30k 100μA CTL VCC 6 8 9 11 15 CTL E CTL D CTL C CTL B CTL A 50k 2k D QP 50k QN 30k VCC QN3 17k 100 QN20 1 MONOUT MONOUT QN2 QN QN6 VCC QN5 200μA 40k 100 10 14 VOUT2 VOUT1 600μA QN20 D VOUT QN QN15 ●Selection of order type B A 7 6 ２ ６ F E 2 Part.
