MM74HCT164M

The MM74HCT164M is an 8-bit serial-in/parallel-out shift register manufactured by ON Semiconductor. It utilizes advanced silicon-gate CMOS technology, offering high noise immunity and low power consumption comparable to low-power Schottky devices.

This shift register features gated serial inputs and a clear function. Each register bit is a D-type master/slave flip-flop. The inputs allow for complete control over incoming data; a low level at either input inhibits new data entry and resets the first flip-flop. Data can be changed at the serial inputs regardless of the clock state, provided setup and hold time requirements are met. Data is serially shifted in and out during the positive-going transition of the clock pulse.

Key electrical specifications include a supply voltage range of 4.5V to 5.5V and an operating temperature range of -40°C to 85°C. The device functions as a serial-to-parallel converter and has a frequency rating of 55 MHz.

The MM74HCT164M is available in a 14-SOIC package and is designed for surface mounting. Its push-pull output type and 8-bit capacity make it suitable for various digital logic applications requiring serial data manipulation and parallel output.
