Description

These 16-bit registered transceivers CY74FCT163H952 are high-speed, low-power devices. 16-bit operation is achieved by connecting the control lines of the two 8-bit registered transceivers together. For data flow from bus A-to-B, CEAB must be LOW to allow data to be stored when CLKAB transitions from LOW-to-HIGH. The stored data will be present on the output  when OEAB is LOW. Control of data from B-to-A is similar and CY74FCT163H952 is controlled by using the CEBA, CLKBA, and OEBA inputs.  The outputs are 24-mA balanced output drivers with current limiting resistors to reduce the need for external terminating resistors and provide for minimal undershoot and reduced  ground bounce. The CY74FCT163H952 has "bus hold" on the data inputs, which retains the input's last state whenever the source driving the input goes to high impedance. CY74FCT163H952 eliminates the need for pull-up/down resistors and prevents floating inputs.
The CY74FCT163952 is designed with inputs and outputs capable of being driven by 5.0V buses, allowing its use in mixed voltage systems as a translator.    The outputs of CY74FCT163H952 are also designed with a power off disable feature enabling its use in  applications requiring live insertion.
