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 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.

NOTES:
1. See test circuits and waveforms.
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.
