4-bit bidirectional universal shift register
Serial and parallel operation are edge-triggered on the
LOW to HIGH transition of CP. The inputs at which the
data are to be entered and S0, S1 must be stable for a
set-up time before the LOW to HIGH transition of CP.
DESCRIPTION
The HEF40194B is a 4-bit bidirectional shift register with
two mode control inputs (S0 and S1), a clock input (CP), a
serial data shift left input (DSL), a serial data shift right input
(DSR), four parallel data inputs (P0 to P3), an overriding
asynchronous master reset input (MR), and four buffered
parallel outputs (O0 to O3). When LOW, MR resets all
stages and forces O0 to O3 LOW, overriding all other input
conditions. When MR is HIGH, the operation mode is
controlled by S0 and S1 as shown in the function table.

Notes
1. H = HIGH state (the more positive voltage)
2. L = LOW state (the less positive voltage)
3. X = state is immaterial
4. tn + 1 = state after next LOW to HIGH transition of CP
