description

The CDC340 is a high-performance clock-driver circuit that distributes one (A) input signal to eight (Y) outputs

with minimum skew for clock distribution. Through the use of the control pins (1G and 2G), the outputs can be

placed in a high state regardless of the A input.

The propagation delays are adjusted at the factory using the P0 and P1 pins. These pins are not intended for

customer use and should be strapped to GND.

The CDC340 is characterized for operation from 0

°C to 70°C.
