Description: 12-bit to 24-bit Registered Bus Exchanger with 3-state Outputs

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

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 is designed specifically for low voltage (from 2.5 V to 3.3 V) VCC operation. Data is
