DESCRIPTION:
The 49FCT805 is a non-inverting buffer/clock driver built using ad-
vanced dual metal CMOS technology. Each bank consists of two banks of
drivers. Each bank drives five output buffers from a standard TTL
compatible input. These devices feature a “heart-beat” 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 49FCT805 offers low capacitance inputs and hysteresis. Rail-to-rail
output swing improves noise margin and allows easy interface with CMOS
inputs.

NOTE:
1. Pin 8 is not internally connected on devices with a "K" prefix in the date code. On older
devices, pin 8 is internally connected to GND. To insure compatibility with all products,
pin 8 should be connected to GND at the board level.
