Figure 6. Shift Right/Shift Left with Parallel Inputs
A “High” (“Low”) on the Shift Left/Shift Right input allows serial data on the Shift Left Input (Shift Right Input) to enter the register
on the positive transition of the lock signal. A “high” on the “A” Enable Input disables the “A” parallel data lines on Reg. 1 and 2
and enables the “A” data lines on registers 3 and 4 and allows parallel data into registers 1 and 2. Other logic schemes may be
used in place of registers 3 and 4 for parallel loading.
When parallel inputs are not used, Reg. 3 and 4 and associated logic are not required.
*Shift left input must be disabled during parallel entry.
