SN74ABT574ADW

Триггер, неинвертированный на 3 состояния, положительный фронт, D, 3.9 нс, 200 МГц, 64 мА, SOIC.

The SN74ABT574ADW is an octal edge-triggered D-type Flip-flop with 3-state outputs. It is 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. On the positive transition of the clock input, the Q outputs are set to the logic levels set up at the data (D) inputs. A buffered 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 need for interface or pull-up 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.
