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

Features

* VCC = 2.3 V to 3.6 V
* Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
* Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
* High output current ±24 mA (@VCC = 3.0 V)
* Bus hold on data inputs eliminates the need for external pullup / pull

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) inpu
