DESCRIPTION

The M54/74HC4094 is a high speed CMOS 8 BIT SIPOSHIFT LATCH REGISTERfabricated with silicon gate C2MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption. This device consists of an 8-bit shift register and an 8-bit latch with 3-state output buffer. Data is shifted serially through the shift register on the positive going transition of the clock input signal. The output of the last stage Qs can be used to cascade sev eral devices.
