ACCESS SHIFT REGISTER
The functional characteristics of the MC74F195 4-Bit Parallel Access Shift
Register are indicated in the Logic Diagram and Function Table. The device
is useful in a wide variety of shifting, counting, and storage applications. It per-
forms serial, parallel, serial-to-parallel, or parallel-to-serial data transfers at
very high speeds.
The MC74F195 operates in two primary modes, shift right (Q0-Q1) and par-
allel load, which 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 1 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 is made for special applications, and by tying the two pins togeth-
er the simple D-type input is made for general applications. The device ap-
pears as four common clocked D flip-flops when the PE input is LOW. After
the LOW-to-HIGH clock transition, data on the parallel inputs (D0-D3) is trans-
ferred to the respective Q0-Q3 outputs. Shift left operation (Q3-Q2) can be
achieved by tying the Qn outputs to the Dn-1 inputs and holding the PE input
LOW.
All parallel and serial data transfers are synchronous, occurring after each
LOW-to-HIGH clock transition. The MC74F195 utilizes edge-triggering;
therefore, there is no restriction on the activity of the J, K, Dn, and PE inputs
for logic operation, other than the setup and hold time requirements.
A LOW on the asynchronous Master Reset (MR) input sets all Q outputs
LOW, independent of any other input condition.
