DESCRIPTION

The M54/74HC4094 is a high speed CMOS 8 BIT
SIPOSHIFTLATCH REGISTERfabricatedwithsili­con gate C2MOS technology.

It has the same high speed performance of LSTTL
combined withtrue CMOSlow power consumption.
This deviceconsists of an 8-bit shiftregister 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 clockinput signal.Theoutput
of the last stage (Qs) can be used to cascadesev­eraldevices.

DataontheQs outputistransferredtoa secondout­put (Qs’) on the following negative transition of the
clockinputsignal. Thedataof eachstageoftheshift
register is provided with a latch,which latches data
on the negative going transition of the STROBE
inputsignal. When the STROBE input is held high,
datapropagatesthroughthelatchtoa3-stateoutput
buffer.

This buffer is enabled when OUTPUT ENABLE
inputistakenhigh. Allinputsare equipped with pro­tectioncircuitsagainststaticdischarge andtransient
excess voltage.
