uPD46184185B Overview
The μPD46184095B and μPD46184185B integrate unique synchronous peripheral circuitry and a burst counter. All input registers controlled by an input clock pair (K and K#) are latched on the positive edge of K and K#. These products are suitable for application which require synchronous operation, high speed, low voltage, high density and wide bit configuration.
