LM1279A Datasheet | National Semiconductor

Description The LM1279A is a full featured and low cost video amplifier with OSD (On Screen Display). 8V operation for low power and increased reliability. Supplied in a 20-pin DIP package, acmodating very pact designs of the video channel requiring OSD. All video functions controlled by 0V to 4V high impedance DC inputs. This provides easy interfacing to 5V DACs used in puter controlled systems and digital alignment systems. Unique OSD switching, no OSD switching signal required. An OSD signal at any OSD input typically switches the LM1279A to the OSD mode within 5 ns. Ideal video amplifier for the low cost OSD monitor with resolutions up to 1024 x 768. The LM1279A provides superior protection against ESD. Excellent alternative for the MC13282 in new designs.
