Description: 12-bit to 24-bit Registered Bus Exchanger 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 data must be transferred from a narrow high speed bus to a wide lower frequency bus. The device provides synchronous data exchange between the two ports. Data is stored in the internal registers on the low to high transition of the clock (CLK) input when the appropriate CLKEN inputs are low. T
