SC14S70FEL

Overview

The SC14S70FEL is a high-speed, low-power CMOS dual serial-to-parallel shift register manufactured by onsemi. It features independent clock inputs for each stage, allowing flexible data shifting operations. The device operates within a supply voltage range of 2.0 V to 5.5 V and supports parallel output loading directly to buses or display drivers. It includes asynchronous reset functionality and is designed for applications requiring reliable data storage and transfer in digital systems.

Feature Summary

• Dual independent clock inputs enable separate control of serial data shifting stages
• Asynchronous reset clears all flip-flops independently of clock signals
• Parallel outputs provide direct interface capability to buses and displays

Applications

• Serial-to-parallel data conversion in communication interfaces
• Display driver data latching for LED and LCD modules
• General-purpose shift register functions in embedded systems

Procurement Notes

Verify the exact suffix FEL against official onsemi documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current datasheets as manufacturing processes may update. Check for any recent lifecycle notices regarding discontinuation or alternative recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-stage serial shifting with independent clocking is required. Ensure the operating voltage matches the system's 2.0 V to 5.5 V range. Consider the package availability and thermal characteristics if high-density PCB layouts are involved. Verify input signal levels are compatible with the logic family specifications.

Part Context

This part belongs to the SCxxS70 series of shift registers, which are widely used in digital electronics for data manipulation. The series offers various configurations including single and dual shift registers with different output types. The SC14S70 variant specifically provides two independent shift stages within a single package for compact design solutions.

Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74HC595 or similar dual shift registers from other manufacturers. Verify electrical parameters like propagation delay and output drive strength match the original design requirements. Ensure the replacement supports the same voltage range and package dimensions.
