74LVT374DB

3.3V八路D型触发器;正边沿触发三态 3.3V Octal D-type flip-flop; positive-edge trigger 3-State

General description

The 74LVT374 is a high-performance product designed for VCC operation at 3.3 V.

This device is an 8-bit, edge triggered register coupled to eight 3-state output buffers. The two sections of the device are controlled independently by the clock pin CP and output enable pin OE control gates. The state of each Dn input one setup time before the LOW-to-HIGH clock transition is transferred to the corresponding flip-flops Qn output.

The 3-state output buffers are designed to drive heavily loaded 3-state buses, MOS memories, or MOS microprocessors.
