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.
