uPD46185084B Overview
The μPD46185084B, μPD46185094B, μPD46185184B and μPD46185364B 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.
uPD46185084B Key Features
- 1.8 ± 0.1 V power supply
