DESCRIPTION
The M74HC194 is an high speed CMOS 8 BIT
PIPO SHIFT REGISTER fabricated with silicon
gate C2MOS technology. This SHIFT REGISTER
is designed to incorporate virtually all of the
features a system designer may want in a shift
register.
It
features
parallel
inputs,
parallel
outputs, right shift and left shift serial inputs, clear
line. The register has four distinct modes of
operation : PARALLEL (Broadside) LOAD ; SHIFT
RIGHT(SR) (in the direction QA QD); SHIFT
LEFT(SL);
INHIBIT
CLOCK
(do
nothing).
Synchronous parallel loading is accomplished by
applying the four data bits and taking both mode
control inputs, S0 and S1 high. The data are
loaded into their respective flip-flops and appear
at the outputs after the positive transition of the
CLOCK input. 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 SHIFT RIGHT data
input. When S0 is low and S1 is high, data shift left
synchronously and new data is entered at the
SHIFT LEFT serial input. Clocking of the flip-flops
is inhibited when both mode control inputs are low.
The mode control inputs should be changed only
when the CLOCK input is high.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
