CD4094BC
8-Bit Shift Register/Latch with 3-STATE Outputs
General Description
The CD4094BC consists of an 8-bit shift register and a 3-
STATE 8-bit latch. Data is shifted serially through the shift
register on the positive transition of the clock. The output of
the last stage (Q
S
) can be used to cascade several
devices. Data on the Q
S
output is transferred to a second
output, Q
S
, on the following negative clock edge.
The output of each stage of the shift register feeds a latch,
which latches data on the negative edge of the STROBE
input. When STROBE is HIGH, data propagates through
the latch to 3-STATE output gates. These gates are
enabled when OUTPUT ENABLE is taken HIGH.

Note 2: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed; they are not meant to imply that
the devices should be operated at these limits. The tables of "Recom-
mended Operating Conditions" and "Electrical Characteristics" provide con-
ditions for actual device operation.
