description

This 4-bit bidirectional universal shift register features parallel (A, B, C, D) inputs, parallel (Q , Q , Q , Q , Q )

outputs, J-K serial (J, K) inputs, shift/load control (SH/LD) input, and a direct overriding clear (CLR). The

registers have two modes of operation:

•

Parallel (broadside) load

Shift (in the direction Q toward Q )

Parallel loading is accomplished by applying the four bits of data and taking SH/LD low. The data is loaded into

the associated flip-flops and appears at the outputs after the positive transition of the clock (CLK) input. During

loading, serial data flow is inhibited.

Shifting is accomplished synchronously when SH/LD is high. Serial data for this mode is entered at the J-K

inputs. These inputs permit the first stage to perform as a J-K, D-, or T-type flip-flop as shown in the function

table.

The SN74AS195 is characterized for operation from 0°C to 70°C.
