MC74HC393ANG

Counter Dividers Overview

The MC74HC393ANG is a dual 4-bit binary counter integrated circuit manufactured by onsemi, belonging to the 74HC logic family. It features two independent counters within a single package, each capable of counting up to fifteen in binary sequence. The device utilizes negative edge-triggered flip-flops for precise timing control and includes an asynchronous reset input for immediate initialization. Designed for surface-mount applications, it operates reliably across a wide voltage range of 2 V to 6 V and supports high-speed counting rates up to 50 MHz. The component is housed in a standard 14-pin DIP package, suitable for through-hole mounting on printed circuit boards.

Counter Dividers Procurement Notes

Verify the specific suffix 'A' and package type 'N' against official datasheets to confirm pinout and electrical characteristics. Ensure the source provides valid RoHS compliance documentation as required for modern electronic assemblies. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Counter Dividers Selection Notes

Select this component when a dual-channel binary counting solution is required in a through-hole DIP package. It is appropriate for designs needing asynchronous reset capabilities and operation within the 2 V to 6 V supply range. Consider the 50 MHz maximum counting rate for speed requirements and ensure the PCB layout accommodates the 14-pin DIP footprint for reliable soldering and mechanical stability.

Counter Dividers Part Context

This part belongs to the widely adopted 74HC series of high-speed CMOS logic devices. The 74HC393 specifically addresses the need for compact, dual-stage binary counting in general-purpose digital electronics. Its compatibility with standard TTL logic levels makes it a versatile choice for interfacing with various microcontrollers and digital systems requiring simple, reliable binary counting functions.

Counter Dividers Replacement Considerations

Compatible substitutes include the MC74HC393ADTR2G (SOIC package) and MC74HC393ADTR2G (TSSOP package). Other manufacturers offer equivalent parts such as the 74HC393PW from Nexperia. Verify pin compatibility and electrical specifications before substitution.
