DESCRIPTION

The M74HC4094 is an high speed CMOS 8 BIT

SIPO SHIFT LATCH REGISTER fabricated with

This device consists of an 8 bit shift register and

an 8 bit latch with 3 state output buffer. Data is

shifted serially trough the shift register on the

positive going transition of the clock input signal.

Theoutput of thelast stage (Qs) canbeusedto

cascade several devices.

Data on the Qs output is transferred to a second

output (Qs’) on the following negative transition of

the clock input signal. The data of each stage of

the shift register is provided with a latch, which

latches data on the negative going transition of the

STROBE input signal. When the STROBE input is

held high, data propagates through the latch to a

3-state output buffer.

This buffer is enabled when OUTPUT ENABLE

input is taken high.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
