... Bus level translation between a very wide range of bus voltages, from 1 supported. This feature provides enormous flexibility in interfacing systems of different technologies. The unique operation of the PCA9521 provides one of the fastest response times of such bidirectional buffers, ensuring any glitches (common to other buffers) are kept well within the accelerators’ ...

... The system shown here uses FET switches, however a valid alternative is to simply use 24 PCA9521’s without FET switches. Long track runs on the ShMC board and backplane can sometimes result in high frequency tuned circuits on either side of the PCA9521. If your layout is prone to forming such tuned circuits perfectly acceptable to use a ‘traditional’ damping resistor (Rd) across the PCA9521. ...

... NXP Semiconductors Peripheral cards (or FRU (Field Replaceable Units)) and backplanes operating at a range of voltages can be interfaced together using a minimum of components. The PCA9521 can be teamed with the PCA9522 to achieve substantial noise margin gains across a system. Multiplexers such as the PCA9544A are simple analog switches which provide no capacitive load isolation between connected branches ...
