To order >>> NTE7104

Description:

The NTE7039 and NTE7104 are vertical deflection output ICs in a 13-Lead SIP type package developed for use in high-grade TVs and displays. The interlace and crosover distortion responses, in particular, have been greatly improved, allowing excellent picture quality on large size television screens and high precision interlace mode displays.

Also, pulse signals can be used for input signals due to the on-chip sawtooth wave generating circuit and driver circuit. Further, the DC and AC feedback circuits be formed with these ICs alone, simplyfing pattern design of sets and ensuring stable performance.

The NTE7104 has a maximum deflection current of 1.8A_P-P, making it appropriate for use in portable to mid-size televisions while the NTE7039 has a minimum deflection current of 2.2A_P-P, so it can be used for larger size sets, and can drive television screen sizes from 33 to 37 inches.

Features:

• Low Power Dissipation due to On-Chip Pump-Up Circuit
• On-Chip 50/60Hz Vertical Size Control Circuit
• On-Chip Sawtooth Wave Generating Circuit
• On-Chip Driver Circuit
• Vertical Output Circuit
• On-Chip Thermal Protection Circuit
• Excellent Interlace Response
• Excellent Crossover Response
