IDT74FCT807BT/CT

FAST CMOS 1-TO-10 CLOCK DRIVER

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.
