SN74LV393ADBR

Counter Dividers Overview

The SN74LV393ADBR is a dual four-bit binary counter from the Texas Instruments SN74LV393A series. It operates within a supply voltage range of 2 V to 5.5 V and features asynchronous reset functionality with negative-edge triggering. The device utilizes a 14-pin SOIC package and supports surface-mount installation. It is designed for high-speed applications, offering a counting rate of 70 MHz across an operating temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Dual independent four-bit binary counters integrated into a single package
• Asynchronous reset mechanism for immediate counter initialization
• Negative-edge triggered clock inputs for precise timing control

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in embedded systems
• Timing and delay generation modules

Counter Dividers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 14-SOIC footprint matches the target PCB design constraints. Ensure compatibility with the intended supply voltage levels between 2 V and 5.5 V before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when dual independent counting channels are required within a compact surface-mount form factor. The LV logic family ensures compatibility with low-voltage digital interfaces while maintaining robust performance at higher frequencies up to 70 MHz. Consider the industrial temperature range if operation in varying environmental conditions is necessary.

Counter Dividers Part Context

This part belongs to the SN74LV393A family of binary counters manufactured by Texas Instruments. It is functionally equivalent to other variants such as the SN74LV393ADR or SN74LV393ANSR, differing primarily in packaging style and reel specifications. The device serves as a fundamental building block for sequential logic designs requiring reliable binary accumulation.
