74HC374; 74HCT374
Octal D-type flip-flop; positive edge-trigger; 3-state
The 74HC374; 74HCT374 is an octal positive?-?edge triggered D?-?type flip?-?flop with 3?-?state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip?-?flops will store the state of their individual D?-?inputs that meet the set?-?up and hold time requirements on the LOW?-?to?-?HIGH clock (CP) transition. A HIGH on OE causes the outputs to assume a high?-?impedance OFF?-?state. Operation of the OE input does not affect the state of the flip??-?flops. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
