DESCRIPTION
The M54/74HCT164 is a high speed CMOS 8 BIT
SIPO SHIFT REGISTER fabricated in silicon gate
C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low
power consumption.
The HCT164 is an 8 bit shift register with serial data
entry and an output from each of the eight stages.
Data is entered serially through one of two inputs (A
or B), either of these inputs can be used as an active
high enable for data entry through the other input.
An unused input must be high, or both inputs connected together. Each low-to-high transition on the
clock input shifts data one place to the right and
enters into QA, the logic NAND of the two data inputs
(A ωB), the data that existed before the rising clock
edge. A low level on the clear input overrides all
other inputs and clears the register asynchronously,
forcing all Q outputs low.
All inputs are equipped with protection circuits
against static discharge and transient excess voltage.
This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL
logic families. M54/74HCT devices are designed to
directly interface HSC2MOS systems with TTL and
NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of
power consumption.
