The FCT16823T 18-bit bus interface registers are 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 FCT16823T is ideally suited for driving high-capacitance loads and
low-impedance backplanes. The output buffers are designed with power off
disable capability to allow "live insertion" of boards when used as backplane
drivers.
