FAST CMOS OCTAL

D REGISTERS (3-STATE)

DESCRIPTION:

TheFCT374isan8-bitregisterbuiltusinganadvanceddualmetalCMOS

technology. These registers consist of eight D-type flip-flops with a buffered

common clock and buffered 3-state output control. When the output enable

(OE) is low, the eight outputs are enabled. When the OE input is high, the

outputs are in the high-impedance state.

Input data meeting the set-up and hold time requirements of the D inputs

is transferred to the O outputs on the low-to-high transition of the clock input.

The FCT374 has non-inverting outputs with respect to the data at the D

inputs.
