Description

The FCT163501/A/C 18-bit registered transceivers are built using advanced dual metal CMOS technology. These high-speed, low-power 18-bit registered bus transceivers combine D-type latches and D-type flip-flops to allow data flow in transparent, latched and clocked modes. Data flow in each direction is controlled by output-enable (OEAB and OEBA), latch enable (LEAB and LEBA) and clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the device operates in transparent mode when LEAB is HIGH. When LEAB is LOW, the A data of IDT74FCT163501C is latched if CLKAB is held at a HIGH or LOW logic level.If LEAB is LOW, the A bus data is stored in the latch/flip-flop on the LOW-to-HIGH transition of CLKAB. EAB performs the output enable function on the B port. Data flow from B port to A port is similiar but requires using OEBA, LEBA and CLKBA. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin.The FCT163501/A/C have series current limiting resistors.These offer low ground bounce, minimal undershoot, and controlled output fall times-reducing the need for external series terminating resistors.
