计数器移位寄存器 IC BUS REG TRE-ST 8STG
The MC74HCT4094A is a high speed CMOS 8bit serial shift and storage register. This device consists of an 8bit shift register and latch with 3state output buffers. Data is shifted on positive clock CP transitions. The data in the shift register is transferred to the storage register when the Strobe STR input is high. The output buffers are enabled when the Output Enable OE input is set high. Two serial outputs QS1, QS2 are available for cascading multiple devices. The MC74HCT4094A can be used to interface TTL or CMOS outputs to high speed CMOS inputs.
