MM74HC393M

Counter Dividers Overview

The MM74HC393M is a dual 4-bit binary counter from the 74HC logic family, manufactured by onsemi. It utilizes advanced silicon-gate CMOS technology and features two independent ripple carry counters within a single package. The device operates on a negative edge clock trigger with an independent clear input for each counter. It supports a supply voltage range of 2V to 6V and functions at typical operating frequencies up to 50 MHz. The component is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package.

Counter Dividers Feature Summary

• Contains two independent 4-bit ripple carry binary counters capable of cascading
• Negative edge triggered clocking with independent asynchronous clear inputs
• High noise immunity and low power consumption via silicon-gate CMOS technology
• Functionally and pinout compatible with standard 74LS logic families

Counter Dividers Applications

• Count truncation and divide-by-N counter configurations
• Cascaded implementations for single divide-by-256 counting
• Digital systems requiring high-speed binary counting operations

Counter Dividers Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm package type and lead-free status. Confirm availability as distribution channels may vary. Ensure the selected variant matches the required SOIC package dimensions and JEDEC standards for your PCB layout.

Counter Dividers Selection Notes

Select this component when a dual-channel binary counting solution is required within a compact surface-mount footprint. Consider the 74HC series compatibility if interfacing with legacy LS-TTL loads is necessary. Evaluate the 2V to 6V supply range requirements against your system's power architecture before finalizing the design.

Counter Dividers Part Context

This part belongs to the broader 74HC393 family of dual 4-bit binary counters. While other manufacturers produce functionally equivalent devices, the MM74HC393M specifically denotes the onsemi version in the narrow SOIC package. It serves as a fundamental building block for sequential logic circuits requiring multiple independent counting stages.

Counter Dividers Replacement Considerations

Direct substitutes include SN74HC393N from Texas Instruments. Verify pinout compatibility and electrical characteristics against the original datasheet specifications before implementation.
