DESCRIPTION:
advanced dual metal CMOS technology. The device consists of two banks
of drivers, each with a 1:5 fanout and its own output enable control. The
device has a "heartbeat" monitor for diagnostics and PLL driving. The
MON output is identical to all other outputs and complies with the output
specifications in this document. The FCT3805B offers low capacitance
inputs with hysteresis.
signal quality and skew are critical. The FCT3805B also allows single
point-to-point transmission line driving in applications such as address
distribution, where one signal must be distributed to multiple recievers with
low skew and high signal quality.
