BA7623F

Multimedia ICs 75Ω driver IC with 3 internal circuits BA7623F The BA7623F is a 75Ω driver-IC developed for use in video equipment. Since the input is coming directly with no bias at the base pin, the DC potential for the previous stage can be used for direct DC coupling. Each output can drive two loads (75Ω × 2). Applications Video cassette recorders, televisions and camcorders Features 1) Can be directly coupled to the previous circuit. 2) Each output can drive two loads. Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature Symbol VCC Pd Topr Tstg Limits 8.0 550∗ – 25 ~ + 75 – 55 ~ + 125 Unit V mW °C °C ∗ Reduced by 5.5mW for each increase in Ta of 1°C over 25°C.
