74HC393D/AUJ

Counter Dividers Overview

The NXP USA Inc. 74HC393D/AUJ is a dual 4-stage binary ripple counter from the 74HC CMOS logic family, housed in a 14-lead SO plastic small outline package (SOT108-1). It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range of -40 °C to +125 °C. The device contains two independent 4-bit counters, each featuring a negative-edge-triggered clock input (nCP) and an overriding asynchronous master reset input (nMR). Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Counter Dividers Feature Summary

• Dual 4-bit binary ripple counters with individual clocks
• Wide supply voltage range from 2.0 V to 6.0 V
• CMOS low power dissipation and high noise immunity
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product data sheet to confirm package type and temperature range specifications. Ensure compatibility with system voltage levels and environmental operating conditions before procurement.

Counter Dividers Selection Notes

Select this component when a dual 4-bit binary counter is required in a surface-mount SOIC package. Verify that the application utilizes CMOS-compatible input levels and operates within the specified 2.0 V to 6.0 V supply voltage range.

Counter Dividers Part Context

This part belongs to the Nexperia 74HC393 series, which includes variants such as the 74HC393PW and 74HC393BQ. These devices are standard dual 4-bit binary ripple counters designed for general-purpose digital logic applications requiring compact packaging and wide voltage operation.

Counter Dividers Replacement Considerations

Direct substitutes include the 74HCT393D for TTL-level input compatibility. Other packages like TSSOP or DHVQFN may require footprint adaptation.
