The MC74HC164ADR2G part is a 8-bit serial in/parallel out shift register manufactured by ON Semiconductor. It features a 2-6V operating voltage range, a high speed operating frequency of 20 megahertz, and a maximum power dissipation of 120 milliwatts. The pinout includes 8 outputs (Q0-Q7) and 5 inputs (CLR, CLK, EN, SER, and R/L), with a low active logic level for the CLR and EN control inputs and a positive edge triggered CLK input. The device can be used as a counter, a shift register, and a storage or latch register to perform data manipulation operations such as right shift or left shift. It is also fully compatible with TTL logic family and accommodates low power Schottky, Standard TTL, and BiCMOS logic. This part is well suited for applications in computing, instrumentation, telecommunications, consumer electronics, and automotive industries.
