General Description
The MAX7456 single-channel monochrome on-screen
display (OSD) generator lowers system cost by elimi-
nating the need for an external video driver, sync sepa-
rator, video switch, and EEPROM. The MAX7456 serves
all national and international markets with 256 user-pro-
grammable characters in NTSC and PAL standards.
The MAX7456 easily displays information such as com-
pany logo, custom graphics, time, and date with arbi-
trary characters and sizes. The MAX7456 is preloaded
with 256 characters and pictographs and can be repro-
grammed in-circuit using the SPI
TM
port.
The MAX7456 is available in a 28-pin TSSOP package
and is fully specified over the extended (-40°C to
+85°C) temperature range.
