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.
■ Wide supply voltage range: 3.0V to 18V
■ High noise immunity: 0.45 VDD (typ.)■ Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS ■ 3-STATE outputs
