• Guaranteed low skew < 600ps (max.)
• Very low duty cycle distortion < 700ps (max.)
• Low CMOS power levels
• TTL compatible inputs and outputs
• TTL level output voltage swings
• High drive: –32mA IOH, 48mA IOL
• Two independent output banks with 3-state control

DESCRIPTION:
The IDT54/74FCT810BT/CT is a dual bank inverting/ non-
inverting clock driver built using advanced dual metal CMOS
technology. It consists of two banks of drivers, one inverting
and one non-inverting. Each bank drives five output buffers
from a standard TTL-compatible input. The IDT54/
74FCT810BT/CT have low output skew, pulse skew and
package skew. Inputs are designed with hysteresis circuitry
for improved noise immunity. The outputs are designed with
TTL output levels and controlled edge rates to reduce signal
noise. Theparthasmultiplegrounds, minimizingtheeffectsof
ground inductance.
– One 1:5 Non-Inverting bank
• ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
• Available in DIP, SOIC, SSOP, QSOP, CERPACK and

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.
