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 (QS) can be used to cascade several
devices. Data on the QS 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.
Features
s Wide supply voltage range: 3.0V to 18V
s High noise immunity: 0.45 VDD (typ.)
s Low power TTL compatibility:
Fan out of 2 driving 74L or 1 driving 74LS
s 3-STATE outputs
