HD74ALVCH16269 Overview
The HD74ALVCH16269 is used in applications where two separate ports must be multiplexed onto, or demultiplexed from, a single port. The device is particularly suitable as an interface between synchronous DRAMs and high speed microprocessors. Data is stored in the internal B port registers on the low to high transition of the clock (CLK) input when the appropriate clock enable (CLKENA) inputs are low.
