DESCRIPTION:
The IDT49FCT805BT/CT and IDT49FCT806BT/CT are
clock drivers built using advanced dual metal CMOS technol-
ogy. The IDT49FCT805BT/CT is a non-inverting clock driver
and the IDT49FCT806BT/CT is an inverting clock driver. Each
device consists of two banks of drivers. Each bank drives five
output buffers from a standard TTL compatible input. The
805BT/CT and 806BT/CT have extremely low output skew,
pulse skew, and package skew. The devices has 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 805BT/CT and
806BT/CT offer low capacitance inputs with hysteresis.
