74HC166FP-E

Shift Registers Overview

The CD74HC166FP-E is an 8-bit parallel-in/serial-out shift register manufactured by Renesas Electronics Corporation. It utilizes high-speed CMOS technology and operates within a supply voltage range of 2 to 6 volts. The device features a serial data input, serial data output, and eight parallel data inputs. It includes dedicated clock, clear, and parallel load control inputs. The component is housed in a 16-pin SSOP package.

Shift Registers Feature Summary

• Provides parallel-to-serial data conversion functionality for digital logic applications
• Operates using high-speed CMOS technology for efficient power consumption
• Includes asynchronous clear input to reset all flip-flops simultaneously

Shift Registers Applications

• Data acquisition systems requiring parallel input buffering
• Serial communication interface expansion circuits
• Digital display scanning and multiplexing logic

Shift Registers Procurement Notes

Verify the specific suffix 'FP-E' against official Renesas documentation to confirm the exact package type and environmental compliance status. Ensure the ordering code matches the required pin configuration and lead finish specifications before procurement.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial converter is required in a compact surface-mount form factor. Confirm that the operating voltage range aligns with the system's power supply rails and that the CMOS logic levels are compatible with the interfacing microcontroller or processor.

Shift Registers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by Renesas Electronics. The 74HC family is designed for compatibility with standard TTL logic levels while offering improved speed and lower power consumption compared to older HC technologies. The FP-E designation indicates a specific plastic small-outline package variant.

Shift Registers Replacement Considerations

Compatible substitutes include the SN74HC166 from Texas Instruments and the MC74HC166A from ON Semiconductor. Verify pinout compatibility and electrical characteristics such as propagation delay and supply current before implementing any cross-manufacturer replacement.
