MC74HC393AD

Counter Dividers Overview

The MC74HC393AD is a dual 4-stage binary ripple counter manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and supports counting rates up to 50 MHz. The device features asynchronous reset functionality and negative edge triggering. It is housed in a 14-SOIC surface-mount package with an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counters
• Asynchronous reset capability
• Negative edge triggered operation
• High noise immunity CMOS technology

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting applications
• Timing sequence control systems
• Cascaded counter configurations for higher modulus division

Counter Dividers Procurement Notes

Verify the exact suffix against the datasheet, as 'MC74HC393AD' may refer to the base part number or specific packaging variants like 'ADR2G'. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Ensure the supplier provides official documentation matching the specific ordering code to avoid pinout or electrical specification mismatches.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counters are required in a single package. It is suitable for designs needing high-speed operation up to 50 MHz and wide voltage flexibility between 2 V and 6 V. Consider the 14-SOIC package for surface-mount assembly needs. Verify compatibility with downstream logic levels, as inputs are compatible with standard CMOS outputs.

Counter Dividers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally identical in pinout to the LS393 but offers improved performance characteristics typical of HC technology. The device is designed for general-purpose digital counting applications requiring reliable operation across industrial temperature ranges.

Counter Dividers Replacement Considerations

Public confirmed substitute part numbers include MC74HC393ADR2G and MC74HC393ADTR2G from onsemi. Other manufacturers such as Toshiba offer equivalent parts like the 74HC393D, though speed specifications may vary.
