The FCT162827T 20-bit buffers are built using advanced dual metal CMOS
technology. These 20-bit bus drivers provide high-performance bus interface
buffering for wide data/address paths or buses carrying parity. Two pair of
NAND-ed output enable controls offer maximum control flexibility and are
organized to operate the device as two 10-bit buffers or one 20-bit buffer. Flowthrough organization of signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
The FCT162827T 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
FCT162827T is a plug-in replacement for the FCT16827T and ABT16827 for
on-board interface applications.
