DESCRIPTION:
The FCT16543T/AT/CT/ET and FCT162543T/AT/CT/ET 16-bit latched transceivers are built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independent 8-bit D-type latched transceivers with separate input and output control to permit independent control of data flow in either direction. For example, the A to-B Enable (xCEAB) must be LOW in order to enter data from the A port or to output data from the B port. xLEAB controls the latch function. When xLEAB is LOW, the latches are transparent. A subsequent LOW-to-HIGH transition of xLEAB signal puts the A latches in the storage mode. xOEABperforms output enable function on the B port. Data flow from the B port to the A port is similar but requires using xCEBA, xLEBA, and xOEBA inputs. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin.
The FCT16543T/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 FCT162543T/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 FCT162543T/AT/CT/ET are plug-in replacements for the FCT16543T/AT/CT/ET and 54/74ABT16543 for on-board bus interface applications.
