CGS74LCT2524
1 to 4 Minimum Skew (300 ps) 3V Clock Driver
General Description
This minimum skew clock driver is a 3V option of the current
CGS74CT2524 Minimum Skew Clock Driver and is designed
for Clock Generation and Support (CGS) applications oper-
ating at low voltage, high frequencies. This device guaran-
tees minimum output skew across the outputs of a given
device.
Skew parameters are also provided as a means to measure
duty cycle requirements as those found in high speed clock-
ing systems. This minimum skew clock driver with one input
driving four outputs, is specifically designed for signal gen-
eration and clock distribution applications.
Logic Symbol
The output pins act as a single entity and will follow the state of the CLK
when the clock distribution chip is selected.
