8-Bit Shift and Store Register (3-state)

The TC74HC4094A is a high speed CMOS 8-BIT SHIFT AND

technology.

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

It consists of an 8-bit shift register and an 8-bit latch with

3-state output buffers. Data is shifted serially though the shift

register on the positive going transition of the CK input. 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 transition of the CK input. The

data in each stage of the shift register is provided to a

corresponding latch, on the negative going transition of the

STROBE input. When STROBE is held high, data propagates

through the latch to a 3-state output buffer. This buffer is

enabled when OUTPUT ENABLE input is set high.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
