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 Ioff. The Ioff 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.
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.
The CY74FCT162H952T is a 24-mA balanced output part that has "bus hold" on the data inputs. The device retains the input\x92s last state whenever the input goes to high impedance. This eliminates the need for pull-up/down resistors and prevents floating inputs.
