74HC93DB,118

Counter Dividers Overview

The 74HC93DB,118 is a high-speed silicon-gate CMOS dual 4-bit binary ripple counter manufactured by NXP USA Inc. It operates within a supply voltage range of 2V to 6V and features an asynchronous master reset input for immediate clearing of counter stages. The device utilizes a 14-pin SSOP package suitable for surface mount applications. It advances on the HIGH-to-LOW transition of the clock input and includes buffered parallel outputs. This component complies with JEDEC standard no. 7A and maintains pin compatibility with low power Schottky TTL (LSTTL) logic families.

Counter Dividers Feature Summary

• Dual independent 4-bit binary ripple counting capability
• Asynchronous master reset function for immediate stage clearing
• Standard output drive capability compatible with LSTTL interfaces

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in digital systems
• Timing control logic requiring asynchronous reset

Counter Dividers Procurement Notes

Verify the specific ordering code 74HC93DB,118 against current Nexperia or NXP distribution channels as product availability may vary. Confirm that the SSOP-14 package matches your PCB footprint requirements. Ensure the operating voltage range of 2V to 6V aligns with your system design before procurement.

Counter Dividers Selection Notes

Select this component when a dual 4-bit binary counter is required with LSTTL pin compatibility. The HCT series offers faster switching speeds compared to standard HC logic. Verify that the asynchronous reset behavior meets the timing requirements of your specific application design.

Counter Dividers Part Context

This part belongs to the 74HC/HCT93 family of dual 4-bit binary ripple counters. It is designed for general-purpose digital logic applications requiring reliable counting functions. The device is part of the broader Nexperia/NXP portfolio of high-speed CMOS logic integrated circuits.

Counter Dividers Replacement Considerations

The 74HCT393DB,118 serves as a functional substitute within the same logic family. Other variants such as the 74HC393 or 74LV393 may also be considered depending on voltage and speed requirements.
