DESCRIPTION:
The IDT54/74FCT810BT/CT is a dual bank inverting/ noninverting clock driver built using advanced dual metal CMOS
technology. It consists of two banks of drivers, one inverting
and one non-inverting. Each bank drives five output buffers
from a standard TTL-compatible input. The IDT54/
74FCT810BT/CT have low output skew, pulse skew and
package skew. Inputs are designed with hysteresis circuitry
for improved noise immunity. The outputs are designed with
TTL output levels and controlled edge rates to reduce signal
noise. The part has multiple grounds, minimizing the effects of
ground inductance.
