• 100MHz operation
• Military product compliant to MIL-STD-883, Class B
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
capacitanceinputswithhysteresisforimprovednoisemargins.
TTL level outputs and multiple power and grounds reduce
noise. The device also features -32/48mA drive capability for
driving low impedance traces.
• TTL compatible inputs and outputs

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.
