DESCRIPTION:
The IDT54/74FCT807BT/CT clock driver is built using
advanced dual metal CMOS technology. This low skew clock
driver features 1:10 fanout, providing minimal loading on the
preceding drivers. The IDT54/74FCT807BT/CT offers low
capacitance inputs with hysteresis for improved noise margins.
TTL level outputs and multiple power and grounds reduce
noise. The device also features -32/48mA drive capability for
driving low impedance traces.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-

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
