IDT74FCT163952B

The IDT74FCT163952B 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 of the IDT74FCT163952B 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 IDT74FCT163952B have series current limiting resistors.These offer low ground bounce, minimal undershoot, and controlled output fall timesreducing the need for external series terminating resistors.
