LM2457 Datasheet Monolithic Triple 7.5ns Crt Driver

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. October 2000 LM2457 Monolithic Triple 7.5nS CRT Driver With Integrated Clamp and G1 Blanking LM2457 Monolithic Triple 7.

General Description

The LM2457 driver is an integrated high voltage triple CRT driver circuit designed for use in color monitor applications.

The input signal interface to the IC is a multiplexed signal containing both clamp and video signal information, relative to an external 1.7 VDC reference.

The IC contains three high gain, differential input, high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT.

Key Features

  • n 7.5ns low power driver n Three integrated active clamp circuits n Integrated 120V supply and G1 vertical blank drive circuit n Multiplexed signal interface to LM125X OSD Pre-amp minimizes pin count while increasing functionality n External System voltage reference n Convenient TO-220 staggered lead package Recommended.
