74HCT393BQ-Q100X

Counter Dividers Overview

The Nexperia 74HCT393BQ-Q100X is a dual 4-bit binary ripple counter housed in a DHVQFN14 (SOT762-1) package. It contains two independent counters, each featuring 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. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The component meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Counter Dividers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Wide operating temperature range specified from -40 °C to +125 °C
• CMOS low power dissipation with high noise immunity
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Counter Dividers Applications

• Automotive electronic systems requiring binary counting
• Frequency division circuits utilizing binary modules up to 2^8
• Digital timing and sequencing logic designs

Counter Dividers Procurement Notes

Verify that the ordering suffix matches the required package type and tape/reel configuration. Confirm the specific grade aligns with project requirements. Ensure compatibility with the intended supply voltage and temperature ranges before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counters are required in a compact surface-mount form factor. The HCT series ensures TTL-compatible input levels suitable for 5 V logic systems. Verify that the DHVQFN14 package dimensions fit the available PCB space constraints.

Counter Dividers Part Context

This part belongs to the Nexperia 74HCT393-Q100 family of dual 4-bit binary ripple counters. It shares functional characteristics with other variants in the series but differs in packaging. The 'BQ' designation specifically indicates the DHVQFN14 package with side-wettable flanks, facilitating automatic optical inspection of solder joints.

Counter Dividers Replacement Considerations

Direct replacements include other packages of the same logical function such as 74HCT393PW-Q100 or 74HCT393D-Q100. Cross-vendor equivalents must be verified for pinout compatibility and electrical specifications.
