Standard 3-output Video Driver
BA7622F, BA7623F
No.09065EAT04
Description The BA7622F and BA7623F are video driver ICs with three built-in circuits, developed for video equipment. The three circuits in the BA7622F, two sync-tip clamp inputs and one bias input, are terminated by internal resistances of 20 k. The BA7623F output pins cab be connected directly in a DC coupling mode. Each output can drive 2 lines of load (75x2). Suitable to connect to a 2Vpp output type signal processing LSI and DAC.
Features Common 1) 2 lines can be driven from each output 2) Can be operated by Vcc=4.5 V BA7622F 1) Large output dynamic range (3.3 Vpp, Vcc=5 V) 2) Built-in, 2 clamp input circuits and1 bias input circuit 3) Y signal, C signal, and composite video signal can be driven simultaneously by this particular IC. BA7623F 1) Wide output dynamic range (3.3 Vpp, Vcc=5 V) 2) Can be directly connected to previous stage circuit
Applications TV, VCR, camcorder, and other video equipment.

Operation Notes 1. 2.
Technical Note
Numbers and data in entries are representative design values and are not guaranteed values of the items. Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits may cause variations in both static and transient characteristics for external components as well as this Rohm IC. Allow for sufficient margins when determining circuit constants. Absolute maximum ratings Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr), may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at times where the absolute maximum ratings may be exceeded. GND potential Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND at any time, regardless of whether it is a transient signal or not. Thermal design Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in actual states of use. Short circuit between terminals and erroneous mounting Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other components on the circuits, can damage the IC. Operation in strong electromagnetic field Using the ICs in a strong electromagnetic field can cause operation malfunction.
