NJM2223M

The NJM2223M is designed as a integrated bipolar video switch with 8dB amplifier which selects one signal from three different composit video signals. It has also function of superimposer and synchronous signal clipping and is suit to picture in picture configuration.

It has eight features. (1)12V operation. (2)3 input video signal. (3)2 output video signal. (4)Switch operates with CMOS level. (5)Super imposer function. (6)Internal 8dB amp. (7)Package outline is DMP16. (8)Bipolar technology. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its supply voltage would be 8V. (2)Its power dissipation would be 300mW. (3)Its operating temperature range would be from -20°C to +75°C. (4)Its storage temperature range would be from -40°C to +125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics are concluded as follow. (1)Its operating current would be typ 14mA and max 19mA. (2)Its voltage gain(1) would be min -1dB and max 1dB. (3)Its voltage gain(2) would be min 7dB and typ 8dB and max 9dB. (4)Its frequency charact would be min -1dB and max 1dB. (5)Its differential gain would be max 3%. (6)Its differential phase would be max 3 deg. (7)Its threshold level would be min 1.4V and typ 2.2V and max 3.0V. (8)Its threshold level with open collector input would be min 0.5V and typ 1.0V and max 2.0V. (9)Its clipping level would be min 32IRE and typ 40IRE and max 48IRE. (10)Its inside white level would be min 92IRE and typ 100IRE and max 108IRE. (11)Its cross-talk would be typ -50dB. It should be noted that this switch has function to make SW(2), SW(3) no working and Vout(2) output signal to the same output signal of Vout(1). It operates in CMOS level. And so on.
