IDT74FCT163646C

The FCT163646 16-bit registered transceiver is built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independant 8-bit bus transceivers with 3-state D-type registers. The control circuitry is organized for multiplexed transmission of data between A bus and B bus either directly or from the internal storage registers. Each 8-bit transceiver/register features direction control (xDIR), over-riding Output Enable control (xOE) and Select lines (xSAB and xSBA) to select either real-time data or stored data. Separate clock inputs are provided for A and B port registers. Data on the A or B data bus, or both, can be stored in the internal registers by the low-to-high transitions at the appropriate clock pins. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin.

The FCT163646 has series current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall timesreducing the need for external series terminating resistors.
