IDT74FCT163952C

The FCT163952A/B/C 16-bit registered transceivers are built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independent 8-bit D-type registered transceivers with eparate input and output control for independent control of data flow in either direction. For example, the A-to-B Enable (xCEBA) must be LOW to enter data from the A port. xCLKAB controls the clocking function.

When xCLKAB toggles from LOW-to-HIGH,the data present on the A port will be clocked into the register.xOEBA performs the output enable function on the B port.Data flow from the B port to A port is similar but requires using xCEBA, xCLKBA, and xOEBA inputs. Full 16-bit operation is achieved by tying the control pins of the independent transceivers together.The FCT163952A/B/C have series current limiting resistors.These offer low ground bounce, minimal undershoot, and controlled output fall timesreducing the need for external series terminating resistors.
