8-Bit Shift Register (S-IN, P-OUT)
The TC74HC164A is a high speed CMOS 8-BIT SERIAL-IN
PARALLEL-OUT SHIFT REGISTER fabricated with silicon gate
C2MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
It consists of a serial-in, parallel-out 8-bit shift register with a
CK input and an overriding CLR input.
Two serial data inputs (A, B) are provided so that one may be
used as a data enable.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
