74HC393N,652

Counter Dividers Overview

The 74HC393N,652 is a dual 4-bit binary ripple counter manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and features two independent counters with individual clock inputs (nCP) and asynchronous master reset inputs (nMR). The device advances on the HIGH-to-LOW transition of the clock signal. It includes input clamp diodes for interfacing with voltages exceeding VCC. The component is housed in a 14-pin SO14 plastic small outline package.

Counter Dividers Feature Summary

• Dual 4-bit binary counters with individual clocks
• Asynchronous master reset functionality
• Input clamp diodes for high-voltage interfacing

Counter Dividers Applications

• Binary counting applications
• Frequency division circuits
• Digital timing systems

Counter Dividers Procurement Notes

Verify the specific ordering suffix '652' against the manufacturer's current documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a dual 4-bit binary counter is required. Verify that the CMOS input levels match the system logic requirements. Confirm the SO14 package fits the PCB layout constraints. Check if the HCT variant is needed for TTL-level input compatibility instead.

Counter Dividers Part Context

This part belongs to the 74HC/HCT series of logic integrated circuits. It is produced by Nexperia, which acquired the standard product business from NXP Semiconductors. The datasheet revision history indicates updates to ESD specifications and package alignment standards over time.

Counter Dividers Replacement Considerations

Direct substitutes include the 74HCT393N,652 for TTL-compatible input levels. Other manufacturers may offer equivalent parts such as the SN74HC393 or MC74HC393, but pinout and electrical characteristics must be verified.
