8-Bit Shift and Store Register (3-state)
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74HC4094A is a high speed CMOS 8-BIT SHIFT AND
STROBE REGISTER fabricated with silicon gate C2MOS
TC74HC4094AP
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
TC74HC4094AF
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.
