These 16-bit registered transceivers 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 is controlled by using the CEBA, CLKBA, and OEBA inputs. The output buffers are designed with a power-off disable feature to allow for live insertion of boards. The CY74FCT16952T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The CY74FCT162952T has 24-mA balanced output drivers with current-limiting resistors in the outputs. This reduces the need for external terminating resistors and provides for minimal undershoot and reduced ground bounce. The CY74FCT162952T is ideal for driving transmission lines.
