说明

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.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

The CY74FCT16952T is ideally suited for driving high-capacitance loads and low-impedance backplanes.
