Product Summary
The SAA5261PS117 is a single-chip ten page 625-line World System Teletext decoder with a high-level command interface, and is SAFARI compatible. The SAA5261PS117 is a single-chip one page version of the SAA5261PS117. Both devices are designed to minimize the overall system cost, due to the high-level command interface offering the benefit of a low software overhead in the TV microcontroller.
