FEATURES
Buffered clock and control inputs
Shift right, shift left, and parallel load capability
Asynchronous Master Reset
DESCRIPTION
The 74F198 Bidirectional Universal Shift Register is designed to
incorporate virtually all of the features a system designer may want
in a shift register. This circuit features parallel inputs and outputs,
shift right and shift left serial inputs, operating mode select inputs,
and direct overriding master reset input. The register has four
distinct modes of operation:
Parallel (broadside) load
Shift right (in the direction Q0 toward Q7)
Shift left (in the direction Q7 toward Q0)
Inhibit clock (do nothing).
Synchronous parallel loading is accomplished by applying the 8 bits
of data and taking both mode control inputs, S0 and S1, High. The
data is loaded into the associated flip-flop and appears at the
outputs after the positive transition of the clock inputs. During
loading, serial data flow is inhibited.
Shift right is accomplished synchronously, with the rising edge of the
clock pulse when S0 is High and S1 is Low. Serial data for this
mode is entered at the right data input (D
SR
). When S0 is Low and
S1 is High, data shifts left synchronously and new data is entered at
the shift-left serial input (D
SL
).
Clocking of the flip-flops is inhibited when both mode control inputs
are Low.

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V

= 5V, T

C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
