HD74ALVCH16269 Datasheet (Hitachi Semiconductor) - 12-bit to 24-bit Registered Bus Transceivers with 3-state Outputs

HD74ALVCH16269, 12-bit to 24-bit Registered Bus Transceivers with 3-state Outputs

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

HD74ALVCH16269 Features
