Automotive Catalog Octal Edge-Triggered D-Type Flip-Flop With 3-State Outputs

The SN74LVC574A octal edge-triggered D-type Flip-Flop is designed for 2.7-V to 3.6-V VCC operation. This device features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing Buffer Registers I/O ports, bidirectional bus drivers, and working Registers On the positive transition of the Clock (CLK) input, the Q outputs are set to the Logic levels at the data (D) inputs. A buffered output-enable (OE) input CAN be used to place the eight outputs in either a normal Logic state (high or low Logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without Interface or pullup components. OE does not affect the internal operations of the Flip-Flops Old data CAN be retained or new data CAN be entered while the outputs are in the high-impedance state. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Inputs CAN be driven from either 3.3-V or 5-V devices. This feature allows the use of thIs device as a translator in a mixed 3.3-V/5-V system environment.
