74AHC374; 74AHCT374
Octal D-type flip-flop; positive edge-trigger; 3-state
The 74AHC374; 74AHCT374 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 are overvoltage tolerant. The 74AHCT374 device features TTL compatible inputs that are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
