74VHC393MTC

Counter Dividers Overview

The onsemi 74VHC393MTC is a dual 4-bit binary counter housed in a 14-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 2.0V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features asynchronous clear inputs and negative-edge triggered counting. Propagation delays vary by output stage, ranging from 14.5 ns to 23.2 ns at 5.0V with 50pF load. Maximum clock frequencies reach up to 170 MHz at 5.0V.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counters integrated into a single package
• Negative-going transition clock triggering for state changes
• Asynchronous high-level clear function resets outputs to low
• Input protection circuitry allows interfacing between mismatched supply voltages

Counter Dividers Applications

• Frequency division circuits
• Binary counting applications
• Digital system timing control

Counter Dividers Procurement Notes

Verify the specific MTC suffix confirms the TSSOP-14 package variant. Confirm RoHS compliance status as the component may be obsolete or subject to production changes. Check current availability as distribution channels may list discontinued stock. Ensure design-in documentation matches the 74VHC logic family specifications.

Counter Dividers Selection Notes

Select this component when dual 4-bit counting is required in a compact surface-mount footprint. The VHC series offers speed comparable to Bipolar Schottky TTL while maintaining CMOS power efficiency. Verify that the 2V to 5.5V operating range aligns with the target system supply rails and signal levels.

Counter Dividers Part Context

This part belongs to the 74VHC logic family, representing advanced high-speed CMOS technology. It serves as a functional equivalent to the 74HC393 but with optimized performance characteristics. The device integrates two separate counters, allowing efficient management of multiple bit streams within limited board space constraints.

Counter Dividers Replacement Considerations

Direct substitutes include the MM74HC393N and MC74HC393ADTR2G. These alternatives maintain pin and function compatibility. Verify package type differences, such as DIP versus TSSOP, before implementation.
