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.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability. No terminal voltage may exceed
VCC by +0.5V unless otherwise noted.

2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. tPLH, tPHL, tSK(t) are production tested. All other parameters guaranteed but not production tested.
4. Propagation delay range indicated by Min. and Max. limit is due to VCC, operating temperature and process parameters. These propagation delay
limits do not imply skew.
