NTE7139 Integrated Circuit Video Output Amplifier
Description: The NTE7139 is a monolithic video output amplifier with a 6MHz bandwidth in a 9-Lead Staggered SIP type medium power package. This device uses high-voltage DMOS technology and is intended to drive the cathode of a CRT. To obtain maximum performance, the amplifier should be used with black current control.

Inputs and output are protected against electrostatic discharge in normal handling. However, to be totally safe, it is desirable to take normal precautions appropriate to handling MOS devices. Note 2. The cathode output is protected against peak currents (caused by positive voltage peaks during high-resistance flash) of 5mA maximum with a charge content of 100C. Note 3. The cathode output is also protected against peak currents (caused by positive voltage peaks during low-resistance flash) of 10mA maximum with a charge content of 100C. Note 4. Human body model: equivalent to discharging a 100pF capacitor through a 1.5k resistor. Note 5. Machine model: equivalent to discharging a 200pF capacitor through a 0 resistor. Note 6. External heatsink not required.
