CD74HCT390M96

Counter Dividers Overview

The CD74HCT390M96 is a high-speed CMOS logic integrated circuit manufactured by Texas Instruments. It contains two independent synchronous decade counters, each featuring four bits of storage and asynchronous reset functionality. The device utilizes negative-edge triggering for clock inputs and supports up-counting operations. It operates within a supply voltage range of 4.5 V to 5.5 V and is rated for an extended industrial temperature range from -55°C to +125°C. The component is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package with a width of 3.90 mm.

Counter Dividers Feature Summary

• Dual independent decade counter architecture
• Asynchronous reset capability for both counters
• Negative-edge triggered clock input mechanism
• Extended industrial temperature rating

Counter Dividers Applications

• Digital frequency division circuits
• Decimal counting systems
• Timing control modules
• Sequential logic state machines

Counter Dividers Procurement Notes

Verify the specific suffix M96 indicates reel packaging configuration distinct from tube variants. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the procurement order matches the required package style and moisture sensitivity level specifications for surface mount assembly processes.

Counter Dividers Selection Notes

Select this component when dual independent decimal counting is required within a single package footprint. The HCT logic series ensures compatibility with standard TTL voltage levels while maintaining CMOS power efficiency. Verify that the 4.5 V to 5.5 V operating range aligns with the system power supply constraints and that the SOIC-16 package fits the available board space.

Counter Dividers Part Context

This part belongs to the Texas Instruments CD74HCT390 family of high-speed CMOS logic devices. The 'M' designation specifies the SOIC surface-mount package, while the '96' suffix typically denotes tape-and-reel packaging for automated assembly. It serves as a digital logic solution for sequential processing tasks requiring decade counting capabilities.

Counter Dividers Replacement Considerations

Compatible substitutes include the CD74HC390M96 for HC series operation and the CD74HCT390E for through-hole DIP packaging. Cross-reference datasheets to ensure pinout compatibility and verify that electrical characteristics such as propagation delay and drive current meet the specific application requirements.
