The 74FCT162823AT/BT/CT 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 74FCT162823AT/BT/CT are 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.

The 74FCT162823AT/BT/CT have 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 FCT162823AT/BT/CT/ET are plug-in replacements for the FCT16823AT/BT/CT/ET and ABT16823 for on-board interface applications.
