74HC37474系列产品详情

The 74HC/HCT374 is an octal positive-edge triggered D-type flip-flop with 3-state outputs. Thedevice features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state of theirindividual 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. The 74HCT374 features reduced input threshold levels to allow interfacing to TTL logic levels.
