Additional Details:
The HD74HC164FPTR is typically available in a surface-mount package (e.g., SOP or TSSOP). It requires a clock signal to shift data through the register, a serial data input pin, and a clear pin for resetting the register. The parallel outputs are available on 8 separate pins. The operating temperature range is typically -40°C to +85°C. The device is suitable for applications where serial-to-parallel data conversion is required, and where high-speed operation and low power consumption are important considerations.
