DESCRIPTION:

The FCT16374T/AT/CT/ET and FCT162374T/AT/CT/ET 16-bit edge-triggered D-type registers are built using advanced dual metal CMOS technology. These high-speed, low-power registers are ideal for use as buffer registers for data synchronization and storage. The Output Enable (xOE) and clock (xCLK) controls are organized to operate each device as two 8-bit registers or one 16-bit register with common clock. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin.

The FCT16374T/AT/CT/ET 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 FCT162374T/AT/CT/ET 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 FCT162374T/AT/CT/ET are plug-in replacements for the FCT16374T/AT/CT/ET and ABT16374 for on-board bus interface applications.
