8-Bit Shift Register (S-IN, P-OUT)
Note:
The TC74VHC164 is an advanced 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
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
It consists of a serial-in, parallel-out 8-bit shift register with a
CLOCK input and an overriding CLEAR input.
Two serial data inputs (A, B) are provided so that one may be
used as a data enable.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
xxxFN (JEDEC SOP) is not available in
Japan.
