Description
The CD40104BMS is a universal shift register featuring parallel
inputs, parallel outputs, SHIFT RIGHT and SHIFT LEFT serial
inputs, and a high impedance third output state allowing the device
to be used in bus organized systems.
In the parallel load mode (S0 and S1 are high), data is loaded into
the associated flip-flop and appears at the output after the positive
transition of the CLOCK input. During loading, serial data flow is
inhibited. Shift right and shift left are accomplished synchronously
on the positive clock edge with serial data entered at the SHIFT
RIGHT and SHIFT LEFT serial inputs, respectively. Clearing the
register is accomplished by setting both mode controls low and
clocking the register. When the output enable input is low, all outputs
assume the high impedance state.
The CD40194BMS is a universal shift register featuring parallel inputs,
parallel outputs SHIFT RIGHT and SHIFT LEFT serial inputs, and a
direct overriding clear input. In the parallel load mode (S0 and S1 are
high), data is loaded into the associated flip-flop and appears at the out-
put after the positive transition of the CLOCK input. During loading,
serial data flow is inhibited. Shift right and shift left are accomplished
synchronously on the positive clock edge with data entered at the
SHIFT RIGHT and SHIFT LEFT serial inputs, respectively. Clocking of
the register is inhibited when both mode control inputs are low. When
low, the RESET input resets all stages and forces all outputs low. The
CD40194BMS is similar to industry types 340194 and MC40194.
