74HCT393DB,118

Counter Dividers Overview

The Nexperia 74HCT393DB,118 is a dual 4-stage binary ripple counter housed in an SSOP-14 package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. Each counter features a clock input (nCP), an asynchronous master reset input (nMR), and four buffered parallel outputs (nQ0 to nQ3). The device advances on the HIGH-to-LOW transition of the clock signal.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counters with individual clocks
• Asynchronous master reset inputs for immediate clearing
• TTL-compatible input levels

Counter Dividers Applications

• Digital counting circuits
• Frequency division applications
• Timing sequence generation

Counter Dividers Procurement Notes

Verify component authenticity through authorized channels. Confirm the specific ordering suffix matches the required package variant. Check current product status as discontinuation notices may apply. Ensure environmental compliance requirements align with project specifications before finalizing procurement.

Counter Dividers Selection Notes

Select this component when dual independent binary counting is required in a compact surface-mount package. Verify that the TTL input logic levels match the driving circuitry. Ensure the operating temperature range covers the intended application environment. Consider power dissipation limits during thermal analysis.

Counter Dividers Part Context
