DESCRIPTION:
The FCT162652T 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 bus transceivers with 3-state D-type registers. For example, the xOEAB and xOEBA signals control the transceiver functions. The xSAB and xSBA control pins are provided to select either real time or stored data transfer. The circuitry used for select control will eliminate the typical decoding glitch that occurs in a multiplexer during the transition between stored and real time data. A low input level selects real-time data and a high level selects stored data. Data on the A or B data bus, or both, can be stored in the internal D-flip-flops by low-to-high transitions at the appropriate clock pins (xCLKAB or xCLKBA), regardless of the select or enable control pins. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin. The FCT162652T has balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times-reducing the need for external series terminating resistors. The FCT162652T is a plug-in replacement for the FCT16652T and ABT16652 for on-board bus interface applications.

NOTES: 1. The data output functions may be enabled or disabled by various signals at the xOEAB or xOEBA inputs. Data input functions are always enabled, i.e., data at the bus pins will be stored on every LOW-to-HIGH transition on the clocks inputs. 2. Select control = L: clocks can occur simultaneously. Select control = H: clocks must be staggered to load both registers. 3. H = HIGH Voltage Level L = LOW Voltage Level X = Don't care = LOW-to-HIGH Transition
