The FCT162823T 18-bit bus interface register is built using advanced, dual
metal CMOS technology. These high-speed, low-power registers with clock
enable (xCLKEN) and clear (xCLR) controls are ideal for parity bus interfacing
in high-performance synchronous systems. The control inputs are organized
to operate the device as two 9-bit registers or one 18-bit register. Flow-through
organization of signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
The FCT162823T 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
FCT162823T is a plug-in replacement for the FCT16823T and ABT16823 for
on-board interface applications.
