Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs

These 8-bit Flip-Flops feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing Buffer Registers I/O ports, bidirectional bus drivers, and working Registers
The eight Flip-Flops of the ?HC374 devices are edge-triggered D-type Flip-Flops On the positive transition of the Clock (CLK) input, the Q outputs are set to the Logic levels that were set up at the data (D) inputs.
An output-enable (OE) input places 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.
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.
