MM74C164 8-Bit Parallel-Out Serial Shift Register
October 1987 Revised January 1999
MM74C164 8-Bit Parallel-Out Serial Shift Register
General Description
The MM74C164 shift registers are a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. These 8-bit shift registers have gated serial inputs and clear. Each register bit is a D-type master/slave flip-flop. A high-level input enables the other input which will then determine the state of the flip-flop. Data is serially shifted in and out of the 8-bit register during the positive going transition of clock pulse. Clear is independent of the clock and accomplished by a low level at the clear input. All inputs are protected against electrostatic effects.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. Except for "Operating Temperature Range" they are not meant to imply that the devices should be operated at these limits. The table of "Electrical Characteristics" provides conditions for actual device operation.
