MC74HC393AFEL

Counter Dividers Overview

The MC74HC393AFEL is a dual 4-bit binary counter from the onsemi 74HC logic family, housed in a 20-SOIC surface-mount package. It operates within a supply voltage range of 2 V to 6 V and supports an up-counting sequence with asynchronous reset functionality. The device utilizes negative-edge-triggered flip-flops for precise timing control. Designed for robust performance, it functions reliably across an extended industrial temperature range of -55°C to +125°C, ensuring stability in demanding electronic environments.

Counter Dividers Procurement Notes

Verify the specific suffix 'AFEL' against current manufacturer documentation to confirm package type and RoHS compliance status. Cross-reference the part number with official onsemi databases to ensure availability and check for any recent product change notices or lifecycle updates before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when a dual-channel binary counter with wide voltage tolerance is required. Ensure the design accommodates the 20-SOIC footprint and validates signal integrity for negative-edge triggering. Confirm that the operating environment remains within the specified -55°C to +125°C thermal limits for optimal reliability.

Counter Dividers Part Context

This part belongs to the 74HC series, known for high-speed CMOS operation compatible with standard TTL logic levels. The MC74HC393 variant specifically provides two separate 4-bit counters in a single package, offering space efficiency compared to using individual single-counter ICs in complex digital designs.
