TEXAS INSTRUMENTS SN74HC374PWT 触发器, 三态非反相, 正沿, D, 19 ns, 70 MHz, 7.8 mA, TSSOP, 20 引脚
The 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. It is 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 that were set up at the data D inputs. An 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 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.
