The FCT16827T 20-bit buffer is 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 FCT16827T 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.
