HD74ALVCHR162269A Datasheet (Hitachi Semiconductor) - 12-bit to 24-bit Registered Bus Exchanger with 3-state Outputs

HD74ALVCHR162269A, 12-bit to 24-bit Registered Bus Exchanger with 3-state Outputs

The HD74ALVCHR162269A is a 12-bit to 24-bit registered bus exchanger, which is intended for applications where two separate ports must be multiplexed onto, or de-multiplexed from, a single port.

It is particularly suitable as an interface between synchronous DRAMs and high speed microprocessors.

The

HD74ALVCHR162269A Features

* All outputs have equivalent 26 Ω series resistors, so no external resistors are required.

* Bus hold on data inputs eliminates the need for external pullup / pulldown resistors. HD74ALVCHR162269A Function Table Inputs CLK ↑ ↑ ↑ OEA H H L OEB H L H Outputs A Z Z Active 1B, 2B Z Act
