CD74HC195 高速 CMOS 逻辑 4 位并行存取寄存器

The device is useful in a wide variety of shifting, counting and storage applications. It performs serial, parallel, serial to parallel, or parallel to serial data transfers at very high speeds.

The two modes of operation, shift right (Q0-Q1) and parallel load, are controlled by the state of the Parallel Enable (PE)\ input. Serial data enters the first flip-flop (Q0) via the J and K\ inputs when the PE\ input is high, and is shifted one bit in the direction Q0-Q1-Q2-Q3 following each Low to High clock transition. The J and K\ inputs provide the flexibility of the JK-type input for special applications and by tying the two pins together, the simple D-type input for general applications. The device appears as four common-clocked D flip-flops when the PE\ input is Low
